I've started a completely dead, 0v battery in a 6.8l V10 gas engine. I did have to let the battery booster charge the dead battery for a few minutes. Cranking was slow, but it did start. Device was in protect mode after engine start. State of charge light was 25%. Plugged in to charge and it was flashing 25% light, so it was pretty dead. The GB40 was definitely not sold as being able to start this large engine, but it still did it. No issues at all starting 1.6l NA and 2.0l turbo engines with 0v battery.
Nice, thanks for the tear-down ; my work career has been in the electronics PCB design for 40+ years. I have a GBX75 and a GB150, they work well. I really like the form-factor on these units too.
On the output is a row of what looks like 4ea 40L45CT 45V 20A SCHOTTKY Low Drop Power Rectifier Diodes in parallel with the center leg cut off. So that seems to be a total of 80A.
They have "Peak Forward Surge Current, 8.3 ms single halfsine-wave " 200A each = 800A total. However the unit is rated for 1000A burst. 8.3ms is nothing. I would think burst current for starting would be a second, at least.
@@HalvardSkurve There are 4 D2PAK, each containing 2 diodes. The I_FSM is rated at around 200-220A per die 10ms non-repetitive. (I_FSM_tot = 1760A). This is sufficient to survive the initial peak current the tiny battery would/could be able to supply at a near short condition. Real world currents will stay significantly below.
Old post.. but is it normal to feel a bit of a bulge through the back of the case? About q 1/3 of the way from the end(opposite to battery end) looking at your video I'd guess it was the black part, between the screw holes on the board, that intersects with the red wire.
I have exactly the same problem as you, just not enough power even after a full charge and trying to start a 1.2 petrol engine. Very unhappy with the purchase. Thanks 👍🏻
The GB40 models have come on leaps and bounds since 2016, the 2018 manufactured GB40's are getting rave reviews, so I purchased one, which I will be giving a real life review here in Finland where the winter gets as low as -35c during winter, should be fun to see if it has indeed moved on since the 2016 model.
I've seen scathing reviews of Noco disappearing out of the blue, makes me think the rave reviews are the result of their PR department and lawyers, not actual quality.
Hello I bought noco gb40 5-6 years ago. All this time I never really use it. It was fully charged inside my car. I tried 3-4 times to jump a car but sadly it didn't make it. I tried it fully charged and with bypass option but nothing. I wonder if inside battery is dead due to lifetime. I should write that I put on charge not often. Every year or every year and half. Could you tell me please if my device could be fixed or is garbage?
I plan to have a booster for my van, this seems great. Right now i bought a diesel heater and i would like to test it but for that i need a power source of 12. I wonder if i could test the diesel heater with the boost mode. The heater uses 10 amps for one minute when the glowplug is heating and then it goes down to quite low amp. Don't feel like buying a extra battery for this test and this product will come to use some day.
i'm really uncertain to buy this or not, i mean, i keep seeing comments talking about false advertising and shit performance, and then on amazon and other parts of the internet lots of good reviews, what's your opinion WOE? would you buy it again?
Great review good product. The mini USB charging port is mounted flimsily. Mine disconnected and I have to try to fix. It broke loose with very little pressure. Other than that I love this product. I have the GB70
I had the same problem. I was able to replace the USB port and I put JB weld on it to hold it in place. No problems since. I also use magnetic USB cables, so no more insert/removal of a USB cable and no risk of damage if cable is ripped off the USB port.
I have one. It will start my one litre petrol car. But only if the battery is just slightly low. ie will barely turn over the engine. If you're lucky, it might even have enough charge for a second start... With my two-litre VW diesel, there is no chance of starting it with this! (Just the preheaters will flatten this quite quickly)... here in the UK it is not a cheap item, and I would probably not buy it again. It's both convenient and small, and will recharge from a phone charger - but nowhere near as good as the makers hype would have you believe...
Richard is talking about a Diesel engine with glow plugs. That needs sustained power. These little lithium ion jump boxes deliver high power for very brief bursts.
Didn't start my Honda 2.2 said it could start up to 3L however no luck here - was dead - the battery was at 5.7 volts and it was cold but not freezing - .
I have a broken china brand portable battery starter. I was able to jump start 2 cars twice when it was new. I charged it then stored for around 6months. When I tried jumping another car, it won't do it anymore. The battery level drops immediately to lowest. I can still use it as a flashlight, cellphone charger, air pump for the tires but onlylast for 1 tire. Can I just remove the internal lipo battery then use the unit as a battery charger? Technically it will be connected to a low bat car battery while it is plugged into the wall outlet.
Mine cannot charge anymore, hiw to fix that? The unit already 4 year but it just use for jumper car and it rarely use about once in a year. I only use the unit about 4 times. How to fix it, do you have suggestion or experience?
Have one, surprised it did not charge anymore after about 4 years, so I bought a new one from Amazon and did a direct swap with my old one, put it in the box and got a refund.....not ethical but was pissed. Let noco take the loss.
Bought one of these , great at first , But after 2 months , it would only give one jump start and then die . These lithium jump starters are ok for a occasional use or for cars with a weak battery . If your car battery is flat as pan cake then you will ruin your booster trying to start ! Also Lithium batters need charging regularly even when not being used
You are 100% right about Noco over rated jump start battery that really work well for lawnmower, small tractor and smaller motor bike. Even my iPad Mini has higher wattage per hour battery than Noco under size battery. 11.1 volt is little too low for some of the starters. Needed LiFe04 3.2 volt x 4 = to 12.8 volts at 10Ah. will work much better than so small battery. Maybe build your own jump start battery that will weight just 10 pounds instead, just 2 pounds.
My opinion is that not all of the product that goes out of the factory will be 100% perfect. Though they have quality control it still happens during the span of time from manufacturing to shipping somewhere. depends on time and place.Anything might occur to the product to have a defect. It's just perhaps that you are one of the lucky person to get that defective product. The good thing is the company is willing to give you a new one.
There is no boost converter in this circuit. 11.1volt is the nominal voltage aka 3.7 x 3 cells. But when the 3 cells 3.7v cells are fully charged they can go as high as 4.25volts each = 12.75Volts. Wooola. No boost needed. "Boost converter" is allready built into the battery standard range of voltage.
First of all, that unit is dead... and there's probably a protection so that shit don't happen if you short them or plug them wrong to the car. That is unless he activates the manual override.
I was wondering if there were any capacitors inside. I would like to use the unit to power 12V items, NOCO told me not to, that it would destroy small items. What do you think?
You probably can but to do that you should go through the bypass and when you go through bypass there is no protection. What are you powering up and for how long?
Same here looking to power a homemade bluetooth speaker with something like this. I'm trying to find out if the jump start output uses caps or basically if it will discharge slowly instead of just instant high amperage power
@@r0llinlacs You could just use a Lithium battery with an undervoltage protection circuit and a charging circuitry. No need for the additional things and the high price of these things. The batteries aren't very big in these jump starters anyways.
I Bought a GB 20 on an auction Site in UK but found that it is not take a charge.. I cant send it back as the site had a 14 day return policy. anybody any idea how I can repair or get new Battery.
I had a problem with my GB40, red and green led lights are flashing and the GB40 does not charge anymore, I wrote to customer service and they sell me a new one half price, can I fix it?
Kingsize what I mean by a time delayed fuse is that it has a run cycle maybe a 25sec delay in the board before it even trys to start detecting higher amps to reset the running mode of the machine to stop putting out high amps and go back to ready start mode a 70 amp fuse would ensure that it would detect amperage every time through the run cycle because it puts out way more amps than that. With that being said it also helps with thermal protection of the parts themself because it only let's itself heat up or put out high amps for a set amount of time. That is why NOCO stresses to not bypass this mode because the safety features are being turned off and your running full amps without the safety features that are built into the board the time delayed fuses that tell the machine to shut down. It's like this if the machine is putting out 900amps and the fuse to tell it to stop is set at 25sec @ 70amps is it going to detect amps and shutdown yes and they would keep the machine from burning up that's what its designed to do.
I still want to know how that black magic works on starting completely dead batteries, I seen a GB40 start a BMW with a dead battery in the trunk, the batteries in BMW's are rated at 900cca's because there in the trunk far from the starter, and that damn thing still started!!
Right. All the arguing about specs, all I know is they work. I made some comments on this vid 3 years ago, still using the same gb40 (albeit rarely), and it still does its job.
To boost car in extreme cold with a completely dead battery you need well over 500amps. If you're in a warmer climate witha undercharged battery you're right anything over 200amps will help.
This unit is designed to do short burst of current and not very suitable for running equipment for long time. So you can do it but the Noco wont power them up for more than couple of hours.
+Aggoony R yes you are right. It wont be the micro control circuitry, I believe it is either the relay or the power rectifier. I need to do further testing. however on the main PCB one of the traces have slight burn mark.
How if people, especially female drivers to handle this situation? I mean they don't know how to connect the wires to the car battery. Many new cars nowadays hide the terminals of the battery,you can't find them then how to connect and use these jump starters?
For your own safety, the next time you're working around a device containing a battery, please remove your conductive jewelry - a battery capable of starting a car can deliver enough energy into that wedding ring that you could loose the finger.
you don't.........the 3S 11.1 lipo inside this boost pack is only rated at 120c. false marketing. there's a few REAL and HONEST teardown vids that reveal how cheap and ineffective this unit is.
it's marketing BS. this pack might be able to provide 150-190 amps for a split second . you MIGHT get one decent "crank" out of this unit with a semi discharged car battery. with a completely dead car battery, you're screwed. these hand held booster packs appeal to people who don't know any better and believe what the packaging states. there are proper jump packs available. for ex - www.amazon.com/Jump-N-Carry-JNC660-1700-12-Volt-Starter/dp/B000JFJLP6/ref=sm_n_ma_dka_US_pr_pub_0_0?sigts=1479680241749&sig=3f9c126892b528618ff7a2721c38549a71276bc0&adId=B000JFJLP6&creativeASIN=B000JFJLP6&linkId=03c36f3cda1903957adc69116e51406d&tag=bestprod06-20&linkCode=w43&ref-refURL=http%3A%2F%2Fbestreviews.com%2Fbest-jump-starters&slotNum=0&imprToken=3qt3rPhSoV9egwzxIqMInQ
the battery is rated at 11.1v 2100mah 120c. that comes out to 252 amps you can draw. (but it's bullshit on this battery. more like 150-200, LIKE I SAID). as for how are you able to draw so many amps from a tiny battery is......lithium polymer batteries can be very small yet pack a huge punch. the lipo's battery chemistry is the reason you're able to draw huge currents from a small battery. i don't know how else to explain it to you.
hmmm 2amp hour , 3600 secs per hour 7200 amps one second. Not likely but at 1000 amps maybe 3 seconds. or for 10 seconds 72 amps. hmm yep it prob wont start a car on its own unless its a newer car with warm engine which normally starts in less than 3 seconds.
Norma Stitz , low resistance means high amperage. There's a chance of the battery exploding. It can also make the ring glow red hot very quickly or weld the connections to the ring.
Those batteries can burn if there is high current long enough for the cells to reach several hundred degrees. I don't expect anyone can hold their ring on the terminals for several minutes. @@judep8920
did you ever do the actual math? theres no way that delivers 1,000 amps peak. only about 4 something what a joke.The fact it didnt even work tells me its junk.Buy some jumper cables...cheaper.
All these tiny lithium "jump starters" are "junk starters". Nothing beats the real thing. i.e. a Black & Decker portable jump starter with a 12V gel cell lead acid battery inside.
That is a really small battery, only 2150 mAh :( My smartphone has a battery with 3100 mAh?? I wonder how a jump-pack with a rated battery of 10000 mAh would stack up to this.
You need to multiply the nominal voltage of the battery by the rated amp hours of the battery. An average samsung phone battery is around 3.8v and this one supplies 11.1v. Your cellphone battery probably is around 11.7 watt hours and this product is around 23.8 Wh
surely it is cheaper to replace the car battery more often and keep it in good condition, only a fool would use a battery thats going to cause problems
There is currently no 18650 battery ( at least that I've heard of ) that can continuously put out more than 45 amps plus the balance charger for he stock battery is for 3 series not four series

Will it power a portable tire inflator?
does it mean that the small 11V/2.5 Ah battery is starting the car directly, without any conversion ??
pretty much. there is a video somewhere with a guy just using a bare battery.
The battery is under size but, you can fix it with just a 10 awg jumper solder on to bypass the relay.
wonder what the part number and source for the battery is? a li-ion with a 400 amp capacity is awesome.
Do you know if the batteries can be changed? Maybe using 18650 pack. Mine has pretty much died ( gb70)

Dan Ray - Marketing hype. But it probably can put out 2000 amps for a couple seconds then die.
I still want to know how that black magic works on starting completely dead batteries, I seen a GB40 start a BMW with a dead battery in the trunk, the batteries in BMW's are rated at 900cca's because there in the trunk far from the starter, and that damn thing still started!!
Right. All the arguing about specs, all I know is they work. I made some comments on this vid 3 years ago, still using the same gb40 (albeit rarely), and it still does its job.
I’m a huge noco fan I own 1 gb150 and 1 gb70 and 2 gb40
Both the gb40 have broken charging ports and I want to reuse the batteries somehow
Just wire your own charging ports
From the sound of the birds in the background.... you're in Australia. I really miss those sounds, which are unique in our world.
You should take the ring off or tape it when you do stuff like that.
my special drive bit is a flat head hehe
alot of people think you need 400 to 500 amps to start your car, this is not true, this is a marketing idea to sell "better" batteries.
You have no idea what you're talking about. Amps needed to turn over engine depends on engine size.
S H And engine compression and air temperature as well as how drained the factory battery is...
To boost car in extreme cold with a completely dead battery you need well over 500amps. If you're in a warmer climate witha undercharged battery you're right anything over 200amps will help.
this jumper is not that strong and will not last. the build quality not bad. It must be a good price and not be used everyday.
I would power a GPS or a small radio.
This unit is designed to do short burst of current and not very suitable for running equipment for long time. So you can do it but the Noco wont power them up for more than couple of hours.
please do an update fixing the cause..
Anyone else only watching to the end to see if he gets shocked to death?
I was cringing my teeth seeing you handle that shit with your metal ring on

How if people, especially female drivers to handle this situation? I mean they don't know how to connect the wires to the car battery. Many new cars nowadays hide the terminals of the battery,you can't find them then how to connect and use these jump starters?
A lot of female drivers know a lot more about cars than a lot of men....... just saiyan
For your own safety, the next time you're working around a device containing a battery, please remove your conductive jewelry - a battery capable of starting a car can deliver enough energy into that wedding ring that you could loose the finger.
If your dead battery has an internal short it can’t be jumped
@10.37 i can see damage on the board
to me it looks like it got wet and fried
HOW do you get 1000 amps PEAK and ~200 amp continuos for a few seconds to jump start a vehicle from a 2150 mAh battery…??
you don't.........the 3S 11.1 lipo inside this boost pack is only rated at 120c. false marketing. there's a few REAL and HONEST teardown vids that reveal how cheap and ineffective this unit is.
Spector NS5 RD So how does a portable jump starter supply ~200 amps of cranking power from a 20k mAh internal battery…??
it's marketing BS. this pack might be able to provide 150-190 amps for a split second . you MIGHT get one decent "crank" out of this unit with a semi discharged car battery. with a completely dead car battery, you're screwed. these hand held booster packs appeal to people who don't know any better and believe what the packaging states. there are proper jump packs available. for ex - www.amazon.com/Jump-N-Carry-JNC660-1700-12-Volt-Starter/dp/B000JFJLP6/ref=sm_n_ma_dka_US_pr_pub_0_0?sigts=1479680241749&sig=3f9c126892b528618ff7a2721c38549a71276bc0&adId=B000JFJLP6&creativeASIN=B000JFJLP6&linkId=03c36f3cda1903957adc69116e51406d&tag=bestprod06-20&linkCode=w43&ref-refURL=http%3A%2F%2Fbestreviews.com%2Fbest-jump-starters&slotNum=0&imprToken=3qt3rPhSoV9egwzxIqMInQ

Back to my question... how do these portable jump starters provide a split second 150-200 amps from a tiny 2100mAh battery..??
the battery is rated at 11.1v 2100mah 120c. that comes out to 252 amps you can draw. (but it's bullshit on this battery. more like 150-200, LIKE I SAID).
as for how are you able to draw so many amps from a tiny battery is......lithium polymer batteries can be very small yet pack a huge punch. the lipo's battery chemistry is the reason you're able to draw huge currents from a small battery. i don't know how else to explain it to you.
2150 MaH! No sale.
You are doing great bro
hmmm 2amp hour , 3600 secs per hour 7200 amps one second. Not likely but at 1000 amps maybe 3 seconds. or for 10 seconds 72 amps. hmm yep it prob wont start a car on its own unless its a newer car with warm engine which normally starts in less than 3 seconds.
the bigger the wire the smaller the gauge
A casual glance will tell you that those leads wont deliver 1000A
Sure they will... for a couple seconds. My welder does a couple thousand amps off cables not much bigger.
The 1000 A would be CCA which includes the power from the alternator. Manufacturers however dont mention this.
If you would read the specs - it delivers 1000 amps over 3 Seconds
wow only 2ah's glad i didnt buy
Take off your ring when opening such things.
why
@@alexeggers6475 Metal conducts electricity. If it were to touch the right two things together, they could short out and make the battery explode.
Bullshit, those two things are called an anode and a cathode and the ring would conduct with little resistance. No explosion @@mandolinman2006
Norma Stitz , low resistance means high amperage. There's a chance of the battery exploding. It can also make the ring glow red hot very quickly or weld the connections to the ring.
Those batteries can burn if there is high current long enough for the cells to reach several hundred degrees. I don't expect anyone can hold their ring on the terminals for several minutes. @@judep8920
did you ever do the actual math? theres no way that delivers 1,000 amps peak. only about 4 something what a joke.The fact it didnt even work tells me its junk.Buy some jumper cables...cheaper.
You know nothing about the batteries inside lol there awesome
All these tiny lithium "jump starters" are "junk starters". Nothing beats the real thing. i.e. a Black & Decker portable jump starter with a 12V gel cell lead acid battery inside.
That is a really small battery, only 2150 mAh :(
My smartphone has a battery with 3100 mAh??
I wonder how a jump-pack with a rated battery of 10000 mAh would stack up to this.
You need to multiply the nominal voltage of the battery by the rated amp hours of the battery. An average samsung phone battery is around 3.8v and this one supplies 11.1v. Your cellphone battery probably is around 11.7 watt hours and this product is around 23.8 Wh
camera + focus
Inside looks like junk

surely it is cheaper to replace the car battery more often and keep it in good condition, only a fool would use a battery thats going to cause problems
9 out of 10 mechanics recommend replacing your car battery 1 day before it is due to fail
"most of the smart happens here" - ha ha - really you don't have a clue on how the circuit board works. Send it to bigclivedotcom.
Is it possible to replace the stock battery with four 18650 batteries?
There is currently no 18650 battery ( at least that I've heard of ) that can continuously put out more than 45 amps plus the balance charger for he stock battery is for 3 series not four series
