As many had already mentioned, you need to press the by-pass button on that GB40 if you want to crank the engine on a completely flat/dead battery. If you open the door and still see interior lights on, then you don’t have to “bypass” safety.
As a mechanic of twenty years I want to clarify the reason you connect the positive leads first. The entire vehicle metal structure is the return path or ground for current flow. When you connect the negative cable first you increase your chances of creating an arc by accidently touching the body of the car with the positive lead that can cause an explosion if the battery still emitting hydrogen as a byproduct of charging a lead acid battery. Keeping this in mind when you disconnect the battery it should always be the negative lead first. Also, if you are every working around an ancient conventional wiring system i.e. red lead to ground then you would do the opposite of this procedure to be safe. I appreciate the info about the jumper batteries I've been eyeing one myself.
My Dad Told me to Connect the Positive Cable First, but was Confused When He Connected the Negative, I thought I had remembered Wrong... Good Follow up 😉👍
You can't create a spark with these...They have protection built in... And had he used the bypass feature of the NOCO.. He would have started it in no time flat....Maybe they should read the instructions. As I started 6 liter diesel with a GB40....
@@WizzRacing this is what I was just thinking. The noco gb40 is rated 3lt diesel. What size is the jeep? Like you say the guy never mentioned the by pass feature so either he is thick and doesn't know about it when he owns 2 models or he is on the pay role from the other model
There is a red button (exclamation point) on the NOCO that overrides the safety system and lets you boost a battery that has less than 2 amps of power. If you press that button for a couple of seconds, the lights will come on and you can boost a car with a dead battery. I have the G B40 and it works fine.
you would think that someone doing a review would read the how to use it book that comes with it or they just trying to make them look bad because they getting paid to do that ethier way not worth watching
So the GB40 jumped the 5.7L? I also have 5.7L Charger am on the fence with the GBX45 (as stated it should be good up to 6.5L)... but after this video, do not really know if i should skip the GBX45 and go for larger size.
I have a GB70 and it has saved me several times... I wasn't going to waste my time with the GB40, solely because of the battery size... I have even jumped completely dead batteries and other people's batteries... The GB70 is the best buy out of all of those in my opinion... The GB70 also holds a charge for a very long time...
I bought the gb40 for my daughter's corolla, she has not needed to use it yet. But has jumped a handful of friends and always worked as advertised. Zero complaints. p.s. always buy when there on sale.
One that I've used for about a year now is SCOSCHE PBJ700-1 PowerUp 700 Portable Car Jump Starter with 15,000 mAh 700A Portable Battery, Dual USB Ports and Built-in LED Flashlight for use with Vehicles, Boats, Motorcycles or ATV/UTV’s. I don't mean this to be an ad for it, but It works great for my Jeep grand Cherokee. Granted, it's only a 6 cylinder, but it starts it from a damn near dead battery instantly. Surprised me the first time I used it at how well it did. Supposedly, it handles 8 cylinders also, but never had the chance to test that. It would start my jeep 5 or 6 times before even getting down to 50% charge. Haven't had to use it for about 4 monthes now, but it still shows all 4 bars of charge after sitting in the back of the jeep all this time. Looks like there are few of these out there that don't stack up. Glad I made the right choice for mine.
I’ve had my GB 40 for a few years now I have started cars that were totally dead or no battery at all. If you have a fully dead battery all you have to do is hit the bypass switch on the GB40 to give it full power. Instructions come with this unit on how to operate when jumpstarting a fully dead battery also if you go on their website they do show you a video on the proper operating procedures for the GB 40.
Most of these reviews of the NOCO have not read the instructions. I have started my Cherokee several times with a GB40 on one charge. It also says to let the unit charge your vehicle battery before you try to start if the battery is dead.
I recently bought the GOOLOO 1500A Peak 20800mAh SuperSafe Car Jump Starter with USB Quick Charge 3.0 (Up to 8.0L Gas, 6.0L Diesel Engine) 12V Auto Battery Booster Portable Charger Power Pack Built-in Smart Protection and I am extremely happy with it so far. It is rated at Starting current 500a(3s), 400a(5s). My daily driver is a 2010 Ford Escape with a 3 liter. I purposely drained the battery completely dead and it started it with no issues at -20c. The battery was warm(it is a new battery so I did not want to ruin it leaving it dead outside overnight) but the vehicle was not plugged in at -20c. That is all I need.
Maybe you have tested the GB40 before this video but otherwise, you can't say it doesn't work when you didn't try once to check if it just was due to a bad connection. Adjusting the clamps and then try again maybe will get a better result. There are lots of amps going through so just a slightly poorly clamped connection will fail the starting test.
i think if you push the red button on the GB40 it does a power override thing and it will actually give you all the power instead of just some of it. Try that and see if it changes your opinion of the product at all.
I bought the Type S from Costco mainly for my 4-stroke snowmobile. -30C here yesterday morning, the brand new battery wouldn’t crank the sled fast enough so I hooked the type s up. 2 slow cranks then all of a sudden it cranked much faster and started right up! The display indicated 99% power left, again this was on a brand new fully charged battery that couldn’t crank the snowmobile fast enough to start in -30C. Also compact enough to carry in my small storage bag on the sled. Type S is rated 200-400AMP 8000mAH at 3.7V. My sled is a ZR7000 fwiw.

I have a BESTEK 600A Peak, got it on amazon about 5 years ago.. it was the best price and had good reviews.. I used it about 6 times. Worked every time on my 2004 rav4. I had a parasitic power drain and i had to use my booster for almost a full week each morning until i could figure out the issue.. Love it.. plus the added flashlight and usb ports are nice..power went out last week and used it to charge my cell phone! As for the genius, it always had mixed reviews even 5 years ago.. Cheers
I have a rather large older jump box with none of the bells and whistles these units have. I've had it for almost 10 years with no issues to date. The only way to recharge it is by plugging it into a 110V outlet which takes about 1 1/2 hours to fully charge but holds the charge for a long period of time between jumps. I live in a very cold environment during the winter months here in northeastern Vermont and has never let me down where CCA's are king! Thanks for sharing. Cheers!
@@boosted2.4_sky Actually, I keep it in my F-350 Super Duty, inside a bolted down tool box in the extended cab area. behind my seat. I removed the jump seats just for a large interior tool box since I never transport passengers.
I now own 3 jump starters. #1 The Nekteck Car Jump Starter Portable External Battery Charger 500A Peak with 12000mAh - Emergency Jump Pack. 500A Peak current and 250A Starting current. #2 The GOOLOO 1500A Peak 20800mAh Super Safe Car Jump Starter with USB Quick Charge 3.0 (Up to 8.0L Gas, 6.0L Diesel Engine) 12V Auto Battery Booster Portable Charger Power Pack. 1500A peak current, Starting current 500A(3sec) 400A(5sec). #3 The TrekPow TJ2500 2500A Peak 18000mAh 12V Auto Battery Booster (Engines up to 9.0L Gas/8.0L Diesel). 2500A peak current and 1000A starting current. I only bought the GOOLOO jump starter. The other 2 were sent to me for reviews. I am really excited to see which one will last the longest and promised the rated specs. The 2 review units were just delivered this week.
I have the gb40 and gb70 and there is a reason I have both. The gb40 did not have the stones and I had to buy the gb70. Thinking about the 150 but I'll be working for free for a couple days
Excellent video. Been looking all afternoon at reviews. This included everything I wasted my time on looking at other reviews, part about lights especially helpful, man just a lot of good tips, good job!
Thanks for the video. 9:45 I believe the 19V is for laptops as this is still a very common power supply voltage for laptops. Interesting to see the GB40 fail. Other videos show great results vith this item but even the GB70 brick did not crank it over any better than the small iClever. I will try a Supercap battery-less starter . It is true that the livespan and the tolerances of LiPo batteries are not so great and this may also be the reason for very different results with this very popular GB*** NOCO units.
A little tip which worked for me. My battery was dead as a dodo. My jump starter pack would not work unless I disconnected the leads ....hooked up to only the leads and then turned the key. Once car is started carefully replace leads to battery and you are good to go. These units will only work hooked up to the battery, if there is a slight charge left in the battery.
If I filing any product that makes false statements on their packages I wouldn't buy their product line at all even if they made a good one. Ashole companies like that. That got me skeptical buying any of these. I'm in the market for one of these or maybe one over the larger ones. Thanks for taking the time
I got one and they work great, way better than a lead-acid battery or charger. I got the BEATIT B10 QDSP 800A and it starts my truck with no problem. Another great thing is they are lightweight and can be taken along on camping and canoe trips to recharge lights, phones, etc.
Awesome video!! I had to laugh though at the fact that you said the NOCO Boost Plus GB40 doesn't work, but were nice enough to link it in the discription. 🤣
In my opion when i buy things like these i go bigger than i will think i need. That way it works for my needs and i have something large enuff for helping someone else out if need. Keep all my basis covered. I have the NOCO GB 150 and love it. Starts my pickups which are gas and diesel in the winter time and also will jump my S300 bobcat when Its 40 below zero in the winter
@@WorkshopAddict i agree it is a pretty penny but the cost of a tow truck or being stranded somewhere in the middle of winter is worth the price tag after 1 use. I consider it my life blood😃
@@bakkencutter189 I have a file that I got from my father that is flat on one side and rounded on the other for the different areas of the chain. I am unsure of it's size. Its been around since I was a kid.
Use it correctly, and the Noco 40 will do what you need it to do. But I second, that the drawbacks of having the 70 (or in my case the GTX75) are so small, that it's just not worth going for the small one. Both fit easily in any trunk, but one of them will work even after being used a couple of times or after being forgotten in the trunk for a year, or if the connections are not optimal. Most importantly, one of them can't loose the leads, whereas the other probably won't have them if you need it, since someone used it as a powerbank and dropped the leads somewhere.
Interestingly my GB40 NOKO works perfect two times I needed:::: on a five year old Interstate , 4:CYL GMC ENGINE AT SOME 20 BELOW ZERO OUTSIDE( NOKO was in 45 DEG Garage= quick start. AND, a second start on Discharged headlights battery in ten year small v8= instant start ( after spooling up,for few seconds).. I run NOKO , XOMPUTER USB CHARGE EVERY YEAR or TWO.. anyways, prob need second Starter in second Vehicle someday, thanks,
Was going to buy a jump starter from Harbor Freight. Saw a bad review of it from Project Farm. Have a couple questions: 1. How does these starters compare to other non lithium ion chargers? 2. Saw someone use a starter in an auction for 100 cars. Is this one a different really high end expensive model? 3. How does the charger compare to just jumping with another car? 4. If harbor freight starter is not good, where should I buy one, that’s cheap. Thanks in advance.
This is already the second faulty GB40 I'm seeing on RUclips. It's interesting how you, guys, get it. As for me, I've been using the GB40 for several years now and started various stranded cars with drained batteries, including my 3.7 V6 MDX one. Effortlessly.
Acura Addicted- He's the SECOND reviewer I've seen to not use the GB40 correctly. Project Farm did the same thing in his review of the GB40, and DIDN'T hit the boost button. Reading the manual first helps, and secondly, intuition should kick in when you see a button with an exclamation point on it.. They are a safer product. Built well. GREAT customer service. Not saying that the other ones don't work, just observing two reviews where they fail to use the Noco correctly.
My gb40 will start my 3.5L v6 like 6-7 times at least. I found out when my alternator failed. I could (and did) jump it over and over, but it wouldn't stay running, or go into drive and go anywhere. So these are great for dead batteries, but on a modern car with a bad alternator, you're still probably screwed. Albeit, you would probably have more warning of charging problems when an alternator is dying. DON'T assume it is the battery and that a booster will always get you home..
I have a GB150 started everything from a diesel RV to my v10 truck boat etc it will do literally everything. Cost more but going on 3 years now and I'd rather have too big of a unit than not enough. Thanks for the tip on not leaving them fully charged I'll take mine down hopefully will last another few years more
Thanks for mentioning the life expectancy of the unit. There is also the need to recharge those things regularly if you want them to be ready when you need them.
That is more of a lead acid thing. Lithium has a much lower discharge rate. Storing at 50% charge supposed to be the best if used infrequently. The noco claims you can store down to -30°C but I bring all my lithium batteries in out of my work truck when it's going below -20°C.
Old video, but I was able to start my 4.0 grand Cherokee several times over with no battery installed in the vehicle and the GB40 started the vehicle with sorta slower than average cranking speed but still popped right off. Kinda odd that it wasn’t able to start this 4.0 in the video
I just use an M12/12v or even in a pinch use an m18/20vMAX battery pack from a tool kit. Relatively simple for people who are carrying tools or have tools around them. I could see those packs for the "average joe" who may not have tool batteries around them or just the normal consumer.
The GB40 sells well here in the UK/Europe where we have a lot of smaller engines cars, typically 1.0 to 1.6 litre petrol and up to around 2 litre diesel for family cars. Small turbo petrols are common. The GB40 is more than sufficient for most. Its true though that the marketing is headline grabbing numbers, making it sound capable of starting 2 or 3 times engine capacity. I'm still using old tech, my Clarke Jumpstart 4000. Stupidly heavy but does the job.
I’ve watched a couple other videos that show you have to push the boost over ride button if the battery is to low, it’s the “!” button. Maybe that’s why it won’t work for you.
I wanted to comment the same thing. He should try reading the directions. I have that exact model and have started diesel tractors with it in the field.
You should read the operating instructions on the Noco boosters before using. If the battery is lower than 2v you need to press and hold the override button for three seconds and then proceed. Instructions are not difficult to read.
@Gregg Sinini I like Project Farm reviews. He is totally unsponsored. He buys all the products just to do the testing. Consider helping him out on patreon.
@Gregg Sinini I bought the Audew based off of Project Farm's testing. It started my 6.6L Duramax in the cold without issue. Turned out I had a bad alternator diode, which has been fixed. The truck would be dead if left to sit for more than 12 hours. Audew battery showed 98% after it started it. 10/10 would recommend.
Agree. The battery is completely dead and he purposely did not push the override button so that the jeep would not start on GB40. Obviously he is promoting iclever. Basically, blowing out someone's candle to make his shine brighter. Hahaha!
The dude said these are usually good for two years. I have a PowerNow jumper that I think is 3 or 4 years old now. Should I be worried about replacing it soon? It still works provided it's charged up.
Yep marketing guys got me again. They went in the trash. Thanks for the tips. Off to get one that will work for our harsh conditions in northern MN. Huge thank you. S
on the iclever (Same a autogen) what does it mean when all LEds blink at the same time when u push the button or connect/disconect the charger? the unit does not produce any function in this error. thank you in advance
Thanks for the video. I’ve owned several of these. I prefer the slow charge rate of the USB input only because I never have to worry about losing a dedicated charger. Thanks for the detail on not leaving it on charge constantly. Of course, like a flashlight, it isn’t doing you any good if it isn’t with you.
I bought a GB40 first unit was not working for me contacted customer service and received a replacement. So far so good. Also if the batteries to low hold down the I button it goes into some type of mode not sure of the name The unit starts blinking and it works with no problem
I have a TackLife T6 which puts out 450 CCA for normal battery boosting and will provide 600 CCA if battery is completely drained and dead. Nice feature! Designed in Taiwan and made in China. American marketing hype and access to the North American advertising market has given jump-starters like the Genius NOCO way too much credit for a product that just performs so-so. I bought my TackLife T6 off Amazon so I could at least see some user reviews and with 4.5 STARS and +100 plus reviews it was worth it to give the TackLife T6 a try. The TackLife T6 performed great and build quality was top notch. Jump--starters are great to have around when you need a boost but make sure you check out the reviews before buying.
Bought the gb 70. Jumped 3 cars in 1 minute in a ferry lineup. One month later it never took a charge again. Look at the 1 star reviews. It’s all the same issue. It works a couple times then wont accept a charge again. It doesn’t last long. Its an expensive throw away gadget. If you buy one. Good luck. Keep jumper cables handy.
I bought a 4s lipo battery that is 5500mah for remote control hobby applications. I have started the cars over 20 times without charging. I have a high compression 4 cylinder that takes a lot of current to start. A v6 honda van. and a v8 range rover classic. Only issue for average user is that it does not have a built in charger. BTW that battery cost me $19 and $10 for ebay clamps.
Thanks for your video very important, so for me the genius noco, gb70, And genius noco gb150 are the best jump started I use both I'm my shop, I recommend!! Thanks!
I see plemty of vids on the 40 showing it works great . One guy had a truck with a complete dead batt that was sitting 6 months and the 40 started it . Sooooo
@@mike7044863 That funny. You need to do a little more watching. Unhooking the battery is the only way to mimic a fully dead battery. Hence, it will not work on a fully dead, or even a battery with one bad cell like the one in my jeep in this video. Doing my best to be truthful here. Maybe I have a bad GB40, but IMHO, it is worth buying the GB70 or something else.
@@WorkshopAddict ....Watch the junkyard vid . That guy starts 6 cars on almost total dead and some had no lights on dash . Looks lagit to me . Just sayin
@@mike7044863 I had light on the dash of the Jeep. No start, boost or not. Maybe I have a bad one, but all the other NOCO stuff I have that is larger works great. Not the 40
I have a gb70. I managed to barely turn over an e-450 with a completely flat group 65 and the v10 motor. It was flat to the point the lights wouldn't race unless I turned off the safety on it. One big jump, and it took about 25% of the packs charge. I'm on the fence about a gb150 now.
I doubt he did that on the video, but I suspect he would have known about the feature, but the disappointing end result would have been the same due to the flaw in the circuitry design.
@@MatthewTaylor3 Many demonstrations of the GB-40 have been successful. It would help if you explain what you mean by a flaw in the circuitry design, rather than just say it.
Not a bad idea. BUT, I would have to mention those Lithium polymer cells are a fire hazard just waiting to go off if they are used wrong. I've seen in the NoCo GB40 the pack puff up and really when you think about it - Well need I say more?. This is where a person needs a better tool to use from time to time - and that is a battery analyzer like the Top Don 100 or the Top Don 200 or the Top Don 300P - This tool sees and when used properly reports the state of health of your battery and can also test how and if your charging system is working properly. I would say that is a far better way to know before hand - before you get stranded by a weak battery. If really needed then use a booster with a AGM pack which is far safer.
I have a generic battery pack ( Chinese ) cost about £30 in Britain $40 in the states and this pack works fine firing up my 1.9 diesel van . So don't have to spend a fortune to get good results.
I had a GB 40 It worked until it was stolen. Then I got the GB 70. after 8 months it swelled like a balloon when I was charging it. I have since gotten a Tacklife T8 Max. It has USB charging, 12Volt output built in. So I got another. What does that say? See you NOGO!

I have the GB40 and you must press the boost button for it to work. It has never failed me.
ruclips.net/video/YB-w_BX1zk4/видео.html
When you used the GB40, you should have press and hold the ! button to activate the max power mode. It will definitely have enough power to start.
😂😂 guy was bashing noco the whole time he's being paid by I clever guranteed. Used the noco many times now no issues
I have used the gb40 on completely dead vehicles . Gotta know how to use the damn things
@MeS&W okay cool but maybe don't review something if you don't even know how to use it 🙃 😅
@MeS&W because he didn't override the safety feature 🙆♂️🤦♂️ are you dense?
@MeS&W completely different video different people nothing applies from that video to this video 🙆♂️
I have a BESTEK 600A Peak, got it on amazon about 5 years ago.. it was the best price and had good reviews.. I used it about 6 times. Worked every time on my 2004 rav4. I had a parasitic power drain and i had to use my booster for almost a full week each morning until i could figure out the issue.. Love it.. plus the added flashlight and usb ports are nice..power went out last week and used it to charge my cell phone! As for the genius, it always had mixed reviews even 5 years ago.. Cheers
We have a red Bestek and it is used mostly for phones because it is such a small size, but it does also perform well starting cars.
I started my ls430 today without a battery using gb40. No issues with the unit at all. I bought it from Amazon couple of days ago.
19v output is useful for a bunch of laptops, and some external displays that take barrel connectors.
I have a rather large older jump box with none of the bells and whistles these units have. I've had it for almost 10 years with no issues to date. The only way to recharge it is by plugging it into a 110V outlet which takes about 1 1/2 hours to fully charge but holds the charge for a long period of time between jumps. I live in a very cold environment during the winter months here in northeastern Vermont and has never let me down where CCA's are king! Thanks for sharing. Cheers!
you drive around with it in your glovebox?.... trunk?
@@boosted2.4_sky Actually, I keep it in my F-350 Super Duty, inside a bolted down tool box in the extended cab area. behind my seat. I removed the jump seats just for a large interior tool box since I never transport passengers.
I did exactly that. I looked at the 40 and bought the 70 because i have a 2005 Suburban with an 8.1 motor.
I now own 3 jump starters.
#1 The Nekteck Car Jump Starter Portable External Battery Charger 500A Peak with 12000mAh - Emergency Jump Pack. 500A Peak current and 250A Starting current.
#2 The GOOLOO 1500A Peak 20800mAh Super Safe Car Jump Starter with USB Quick Charge 3.0 (Up to 8.0L Gas, 6.0L Diesel Engine) 12V Auto Battery Booster Portable Charger Power Pack. 1500A peak current, Starting current 500A(3sec) 400A(5sec).
#3 The TrekPow TJ2500 2500A Peak 18000mAh 12V Auto Battery Booster (Engines up to 9.0L Gas/8.0L Diesel). 2500A peak current and 1000A starting current.
I only bought the GOOLOO jump starter. The other 2 were sent to me for reviews. I am really excited to see which one will last the longest and promised the rated specs. The 2 review units were just delivered this week.
I have the gb40 and gb70 and there is a reason I have both. The gb40 did not have the stones and I had to buy the gb70. Thinking about the 150 but I'll be working for free for a couple days
Excellent video. Been looking all afternoon at reviews. This included everything I wasted my time on looking at other reviews, part about lights especially helpful, man just a lot of good tips, good job!
Thanks for your great video! You provided me with the vital differences I was looking for in these two Noco models. Keep up the good work!
Thanks for the video. 9:45 I believe the 19V is for laptops as this is still a very common power supply voltage for laptops. Interesting to see the GB40 fail. Other videos show great results vith this item but even the GB70 brick did not crank it over any better than the small iClever. I will try a Supercap battery-less starter . It is true that the livespan and the tolerances of LiPo batteries are not so great and this may also be the reason for very different results with this very popular GB*** NOCO units.
A little tip which worked for me. My battery was dead as a dodo. My jump starter pack would not work unless I disconnected the leads ....hooked up to only the leads and then turned the key. Once car is started carefully replace leads to battery and you are good to go. These units will only work hooked up to the battery, if there is a slight charge left in the battery.
I just ordered the GB40... I hope it works!
If I filing any product that makes false statements on their packages I wouldn't buy their product line at all even if they made a good one. Ashole companies like that. That got me skeptical buying any of these. I'm in the market for one of these or maybe one over the larger ones. Thanks for taking the time
I got one and they work great, way better than a lead-acid battery or charger. I got the BEATIT B10 QDSP 800A and it starts my truck with no problem. Another great thing is they are lightweight and can be taken along on camping and canoe trips to recharge lights, phones, etc.
Awesome video!! I had to laugh though at the fact that you said the NOCO Boost Plus GB40 doesn't work, but were nice enough to link it in the discription. 🤣
In my opion when i buy things like these i go bigger than i will think i need. That way it works for my needs and i have something large enuff for helping someone else out if need. Keep all my basis covered. I have the NOCO GB 150 and love it. Starts my pickups which are gas and diesel in the winter time and also will jump my S300 bobcat when
Its 40 below zero in the winter
I keep my GB 150 at the shop and feel that is too expensive for most non-business people to consider, but it rocks.
@@WorkshopAddict i agree it is a pretty penny but the cost of a tow truck or being stranded somewhere in the middle of winter is worth the price tag after 1 use. I consider it my life blood😃
@@bakkencutter189 I agree with you 100 percent, but I think we are the minority in this opinion.
@@WorkshopAddict Off topic question but what size of file do you use to sharpen the chain on the Milwaukee chainsaw?
@@bakkencutter189 I have a file that I got from my father that is flat on one side and rounded on the other for the different areas of the chain. I am unsure of it's size. Its been around since I was a kid.
Hey thanks I've been looking at battery jumpers for a while it helps narrow down the choices keep up the great work cheers with a beer take care man
Use it correctly, and the Noco 40 will do what you need it to do. But I second, that the drawbacks of having the 70 (or in my case the GTX75) are so small, that it's just not worth going for the small one. Both fit easily in any trunk, but one of them will work even after being used a couple of times or after being forgotten in the trunk for a year, or if the connections are not optimal. Most importantly, one of them can't loose the leads, whereas the other probably won't have them if you need it, since someone used it as a powerbank and dropped the leads somewhere.
I have both GB40 and a GB70. I've had zero issues with them.
Kiitoksia esittelyssä..tää oli hyvä filmi...ja hyvää jouluu kaikille
Interestingly my GB40 NOKO works perfect two times I needed:::: on a five year old Interstate , 4:CYL GMC ENGINE AT SOME 20 BELOW ZERO OUTSIDE( NOKO was in 45 DEG Garage= quick start. AND, a second start on Discharged headlights battery in ten year small v8= instant start ( after spooling up,for few seconds).. I run NOKO , XOMPUTER USB CHARGE EVERY YEAR or TWO.. anyways, prob need second Starter in second Vehicle someday, thanks,
Great info....never even thought about the placement of the light in these things
Was going to buy a jump starter from Harbor Freight. Saw a bad review of it from Project Farm. Have a couple questions:
1. How does these starters compare to other non lithium ion chargers?
2. Saw someone use a starter in an auction for 100 cars. Is this one a different really high end expensive model?
3. How does the charger compare to just jumping with another car?
4. If harbor freight starter is not good, where should I buy one, that’s cheap.
Thanks in advance.
Micro-start XP-10 is one of the original ones. Underrated, start current is labeled as 300 amps, peak 600. But it starts diesel trucks
This is already the second faulty GB40 I'm seeing on RUclips. It's interesting how you, guys, get it. As for me, I've been using the GB40 for several years now and started various stranded cars with drained batteries, including my 3.7 V6 MDX one. Effortlessly.
Acura Addicted he gets paid to talk down on the GB40 , I call BS
Acura Addicted- He's the SECOND reviewer I've seen to not use the GB40 correctly. Project Farm did the same thing in his review of the GB40, and DIDN'T hit the boost button. Reading the manual first helps, and secondly, intuition should kick in when you see a button with an exclamation point on it.. They are a safer product. Built well. GREAT customer service. Not saying that the other ones don't work, just observing two reviews where they fail to use the Noco correctly.
My gb40 will start my 3.5L v6 like 6-7 times at least. I found out when my alternator failed. I could (and did) jump it over and over, but it wouldn't stay running, or go into drive and go anywhere. So these are great for dead batteries, but on a modern car with a bad alternator, you're still probably screwed. Albeit, you would probably have more warning of charging problems when an alternator is dying. DON'T assume it is the battery and that a booster will always get you home..
I bought a Beatit QDSP 800 and for my 2.5L it works great.
Just bought the AVAPOW 23.8k AH. Good video thanks.
Interested if you wait 30 secs after you connect GB40 you try starting? Manual says some cars require 30 secs followed by another 30 secs.
I have a GB150 started everything from a diesel RV to my v10 truck boat etc it will do literally everything. Cost more but going on 3 years now and I'd rather have too big of a unit than not enough. Thanks for the tip on not leaving them fully charged I'll take mine down hopefully will last another few years more
19 volts is for laptops and small tv's that use a "brick" voltage converter that converts 120 V AC to 19 V DC.
Thanks for mentioning the life expectancy of the unit. There is also the need to recharge those things regularly if you want them to be ready when you need them.
That is more of a lead acid thing. Lithium has a much lower discharge rate. Storing at 50% charge supposed to be the best if used infrequently. The noco claims you can store down to -30°C but I bring all my lithium batteries in out of my work truck when it's going below -20°C.
Old video, but I was able to start my 4.0 grand Cherokee several times over with no battery installed in the vehicle and the GB40 started the vehicle with sorta slower than average cranking speed but still popped right off. Kinda odd that it wasn’t able to start this 4.0 in the video
did you try the noco boost button?
I just use an M12/12v or even in a pinch use an m18/20vMAX battery pack from a tool kit. Relatively simple for people who are carrying tools or have tools around them. I could see those packs for the "average joe" who may not have tool batteries around them or just the normal consumer.
4thewin the m18 has saved me in a pinch multiple times!
The GB40 sells well here in the UK/Europe where we have a lot of smaller engines cars, typically 1.0 to 1.6 litre petrol and up to around 2 litre diesel for family cars. Small turbo petrols are common. The GB40 is more than sufficient for most. Its true though that the marketing is headline grabbing numbers, making it sound capable of starting 2 or 3 times engine capacity. I'm still using old tech, my Clarke Jumpstart 4000. Stupidly heavy but does the job.
They all work great on motorcycle batteries, which seem to be dead a lot more often. Must have for riders.
I’ve watched a couple other videos that show you have to push the boost over ride button if the battery is to low, it’s the “!” button. Maybe that’s why it won’t work for you.
I wanted to comment the same thing. He should try reading the directions. I have that exact model and have started diesel tractors with it in the field.
I have an iClever, the next one bigger than that, and it has worked great the few times I've left my lights on.
You should read the operating instructions on the Noco boosters before using. If the battery is lower than 2v you need to press and hold the override button for three seconds and then proceed. Instructions are not difficult to read.
Well it looks like iClever starters went out of business
Look at Project Farm testing of several jumpers.
@Gregg Sinini I like Project Farm reviews. He is totally unsponsored. He buys all the products just to do the testing. Consider helping him out on patreon.
@Gregg Sinini I got a Sanrock based on PF's testing results
What about the mophie powerstation go?
@Gregg Sinini I bought the Audew based off of Project Farm's testing. It started my 6.6L Duramax in the cold without issue. Turned out I had a bad alternator diode, which has been fixed. The truck would be dead if left to sit for more than 12 hours. Audew battery showed 98% after it started it. 10/10 would recommend.
i just bought the Audew based on his recommendation
My GB40 has always worked very well for me
great comparison
The gb40 will easily crank a stone cold dead 6.0 liter Chevy 2500 HD. You just have to press the override button on a completely dead battery!
Agree. The battery is completely dead and he purposely did not push the override button so that the jeep would not start on GB40. Obviously he is promoting iclever. Basically, blowing out someone's candle to make his shine brighter. Hahaha!
No guys, battery was not dead... to prove it, watch this ruclips.net/video/YB-w_BX1zk4/видео.html
The dude said these are usually good for two years. I have a PowerNow jumper that I think is 3 or 4 years old now. Should I be worried about replacing it soon? It still works provided it's charged up.
Yep marketing guys got me again. They went in the trash. Thanks for the tips. Off to get one that will work for our harsh conditions in northern MN. Huge thank you. S
How about you and the fella in this video get together and properly read the Noco instructions before throwing anything in the bin?
Which drill bits are the best ?
Thanks you just saved me grief & money.
Do you think if you would've done manual override on the gb40 would it have made a difference? Thank you.
No, because the GB40 was on because the battery had more than 2 volts. It makes zero difference.
@@WorkshopAddict ok. Thanks for the response.
on the iclever (Same a autogen) what does it mean when all LEds blink at the same time when u push the button or connect/disconect the charger? the unit does not produce any function in this error. thank you in advance
Thanks for the video. I’ve owned several of these. I prefer the slow charge rate of the USB input only because I never have to worry about losing a dedicated charger. Thanks for the detail on not leaving it on charge constantly.
Of course, like a flashlight, it isn’t doing you any good if it isn’t with you.
I bought a GB40 first unit was not working for me contacted customer service and received a replacement. So far so good. Also if the batteries to low hold down the I button it goes into some type of mode not sure of the name The unit starts blinking and it works with no problem
Adv1227 yes you have press and hold the button for more than three seconds.
It's called the surge mode
try the OVERRIDE button to make it useful on dead battery
Hi workshopadic i buy one iclever and it come whit cero charge, how can i do for charge it, i plug it and it doesn't get charge???
I have a TackLife T6 which puts out 450 CCA for normal battery boosting and will provide 600 CCA if battery is completely drained and dead. Nice feature! Designed in Taiwan and made in China. American marketing hype and access to the North American advertising market has given jump-starters like the Genius NOCO way too much credit for a product that just performs so-so. I bought my TackLife T6 off Amazon so I could at least see some user reviews and with 4.5 STARS and +100 plus reviews it was worth it to give the TackLife T6 a try. The TackLife T6 performed great and build quality was top notch. Jump--starters are great to have around when you need a boost but make sure you check out the reviews before buying.
Bought the gb 70. Jumped 3 cars in 1 minute in a ferry lineup. One month later it never took a charge again. Look at the 1 star reviews. It’s all the same issue. It works a couple times then wont accept a charge again. It doesn’t last long. Its an expensive throw away gadget. If you buy one. Good luck. Keep jumper cables handy.
Thankyou for your time
My Gb 40 works great
Starts my big V8 every time
I bought a 4s lipo battery that is 5500mah for remote control hobby applications. I have started the cars over 20 times without charging. I have a high compression 4 cylinder that takes a lot of current to start. A v6 honda van. and a v8 range rover classic. Only issue for average user is that it does not have a built in charger. BTW that battery cost me $19 and $10 for ebay clamps.
I have the little red one. Have started a few engines, mostly other peoples, my motorbike twice over winter
So which of these would you recommend ?
Noco 70 or above
Project farm just did this same review on quite a few of these a couple days ago
So that gb70 would be okay on a smaller car? 1.2 litre say
I don't think you did turn on the switch on the gb 40
Thanks for your video very important, so for me the genius noco, gb70, And genius noco gb150 are the best jump started I use both I'm my shop, I recommend!! Thanks!
I see plemty of vids on the 40 showing it works great . One guy had a truck with a complete dead batt that was sitting 6 months and the 40 started it . Sooooo
Soooooo.... Watch this.... #Truth ruclips.net/video/YB-w_BX1zk4/видео.html
@@WorkshopAddict .....seems unhooking batt is the problem . Well whos going to do that ? Leave it
@@mike7044863 That funny. You need to do a little more watching. Unhooking the battery is the only way to mimic a fully dead battery. Hence, it will not work on a fully dead, or even a battery with one bad cell like the one in my jeep in this video. Doing my best to be truthful here. Maybe I have a bad GB40, but IMHO, it is worth buying the GB70 or something else.
@@WorkshopAddict ....Watch the junkyard vid . That guy starts 6 cars on almost total dead and some had no lights on dash . Looks lagit to me . Just sayin
@@mike7044863 I had light on the dash of the Jeep. No start, boost or not. Maybe I have a bad one, but all the other NOCO stuff I have that is larger works great. Not the 40
Have u tested in -30 degrees? Or any recommendations which will work?
I have a Hulkman 85s which is rated down to -40 The digital readout is so much nicer than just a few leds.
Many laptops, including popular brands like HP and Dell, use 19V. So I guess that's what the 19V outlet is for.
I should watch your video before I got the noco g40 I haven’t start a car with it
Did you try the boost mode by holding the override button? I just seen in another video about it and curious
I have a gb70. I managed to barely turn over an e-450 with a completely flat group 65 and the v10 motor. It was flat to the point the lights wouldn't race unless I turned off the safety on it. One big jump, and it took about 25% of the packs charge.
I'm on the fence about a gb150 now.
my gb40 will start my 97 sahara all day long ,i dont know what yer trying to pull here?
Damn I just bought a gb40 hope it works when I need it...
On the GB-40, did you try the override mode?
I doubt he did that on the video, but I suspect he would have known about the feature, but the disappointing end result would have been the same due to the flaw in the circuitry design.
@@MatthewTaylor3 Many demonstrations of the GB-40 have been successful. It would help if you explain what you mean by a flaw in the circuitry design, rather than just say it.
How long do these units generally last?
How do you feel about the Hulkman jumpers?
Not a bad idea. BUT, I would have to mention those Lithium polymer cells are a fire hazard just waiting to go off if they are used wrong. I've seen in the NoCo GB40 the pack puff up and really when you think about it - Well need I say more?.
This is where a person needs a better tool to use from time to time - and that is a battery analyzer like the Top Don 100 or the Top Don 200 or the Top Don 300P - This tool sees and when used properly reports the state of health of your battery and can also test how and if your charging system is working properly. I would say that is a far better way to know before hand - before you get stranded by a weak battery.
If really needed then use a booster with a AGM pack which is far safer.
The red light on my audew jumpstarter won't go off, what should I do?
19V powers most laptops, certainly in the UK, with the right adapter.
I have a generic battery pack ( Chinese ) cost about £30 in Britain $40 in the states and this pack works fine firing up my 1.9 diesel van . So don't have to spend a fortune to get good results.
sorry my Gb40☹️ but tomorrow morning I'll take you back to the store. welcome Gb70
I had a GB 40 It worked until it was stolen. Then I got the GB 70. after 8 months it swelled like a balloon when I was charging it. I have since gotten a Tacklife T8 Max. It has USB charging, 12Volt output built in. So I got another. What does that say? See you NOGO!
Awesome review. I've seen the same result with the GB 40 in other reviews, but yours was very informative.
