This time we have the NOCO GB70 Jump Starter to put to the test.
no.co/gb70
Before pushing the magic button and letting out the smoke, let's go over some basic electrical theory on how to characterize a battery in terms of energy capacity and current output.
In Part 1 we break down the jargon when talking about batteries...Amps, Watts, Volts, energy, power, current...Joules?
Grab your notebook, pencil, and some brain cells...
Enjoy!

Thank you so much for this long but enlightening review. I wish all reviews were as thorough and educational.
I love these reviews you do, can't wait for part 2! the feature I like about this thing is the boost button that doesn't time out like the pocket power... mandatory for diags or pulling power from the leads for powering something.
Bet you never thought your video would still be enlightening folk and being rewound countless times four years after you made it did ya!?
Well done. I must say, it kinda inspires me to dip my toe in auto tech videos. Thank you.
Maybe more info/physics than I was researching; but you had me looking for #2. Thx. More.
excellent. used about 10 times. used it yesterday and today. on a buick and a honda. cars started immediately. once i had to use the override and it started immediately.
I carry one of those in my car. I only use it once in a while, so the USB is fine. Mine also times out. The size of the wire and the beefiness (or lack of) is a clue to what your gonna get. Thank u Ivan!
Thought I might find this boring but not! Great lesson even for an old man! Thanks for sharing!
Thanks for the feedback, Rick! I was hoping the lecture wouldn't get too boring.
Excellent video Ivan!
Ive got 2 of those "pocket power" units, they are called "thunder" in Australia, I'm very happy with them, they will crank a 6.oL petrol engine individually and I have started a 9L diesel engine on 24V with one on each battery, both times with completely dead vehicle batteries.
Very interesting review now understand Apollo 13 problem with lem good job
Hi Ivan
It has been quite a long time since I did any quantitative energy measurements. glad to get the refresher.
I am expecting a little explanation of the reason the joules ar listed. Theya are stored available energy correct. and the unit I am expecting is a combination of battery and capicitor or strictly a capicitor. I expect it will lose it's stored charge quite quickly and if not kept frequently recharged will not provide much boost power. Take the starting battery out of the circut and see if the unit will repeatedly start the car. Or short the ignition and see how long the unit will keep cranking the car. Both valid tests and easy for the lay person to compare with the starting battery.
Looking forward to part 2.
Great review Ivan, half of your audience won't have a clue of what you're talking about. But for the rest of us it's a well rounded review. Keep 'em coming.
Well I just hoped to spak an interest in the physics and math behind the real world applications. Hope it wasn't too boring lol
Nice review Ivan. Your content on youtube is very helpful. keep it up :)
Love this explanation. Thank you
I bought one about 6 months ago, it's excellent. They say it only works on single battery cars/trucks. Not so, my Montero has 2 batteries, I attach the GB70 to the battery closest to the firewall and it starts on the button as this is the battery wired direct to the starter. Attaching the GB70 to the other battery is no good.
I got the AC adapter from NOCO for my GB150 and it works great for charging that BadBoy up!!!👍
Irish song goes like this-"She wore no joules nor costly diamonds, no paint or powder, no none at all" Great video and love the basics.
She sounds like a real live wire 😉
Nice Ivan. Kind of like Engineering Explained but better because you also fix stuff! Thanks.
Just channeling the inner nerd on this one...just to prove some stuff you learn in school isn't useless haha
Great video. What's your opinion on the GB150? I need a jump starter to be able to start mostly 2.5 diesel engines to 7.2 liter petrol V8 engines, let's say 2 or 3 times a day in general. Would i have enough with the GB70, or would the GB150 be better. Thanks
Hey,I was able to follow, pretty much. Wish I had a Prof. with such ability.
Dood!! any one can tell me
If this units work in Manitoba (Canada) when temperatures drop - 50 below??
Would a slow charge (1 amp) each time, preserve the life of the lithium battery, opposed to a quick charge ?
Ohms Law E over IR and Watts Law P over IE. That’s all you need to know along with Kirchhoff’s Law and Voltage stays constant in a parallel circuit/current divides versus Current stays constant in a series circuit and voltage divides.
I am not a techie! Excuse my probably dumb question but can I charge my NOCO 70 by going through clamps to clamps with a 120V trickle charger ( wall plug in)?
Great scientific tool review
Nice video. Hoping you will compare what you think of these lithium ion batteries vs the much cheaper jump starters with the lead acid batteries. Because here's my thing. Much easier for the average guy to afford to put one in more than one vehicle (which I do btw) so I'm hoping you will discuss this somewhat even though I know that's not what you are reviewing. Also was glad to watch your videos and Eric O's and scanner danners at the meet and greet with Eric the car guy. You with the analytic mind and Eric O with the analytic mind and tons of experience is fun to watch. Like Scanner Danners channel also. Thanks !
Ivan the Teacher. ;-)
Nice walk through, good job. However, might I persuade you to use Engineering Notation (as it corresponds to the SI prefixes) making it easier to compare values?
Anyway, looking forward to the sequel.
Important to take in to account that starter lead acids usually can only consistently provide about half of their Ah-rating when discharging, otherwise they wear down quickly.
I don’t understand how these works. Are these capacitor boost or what. Never really looked into it.
Good stuff, Ivan. I wonder how you calculate 201 K Joules, yet the advertising on the front of the unit only says 15.7 kJ? I thought they always over-inflated the advertising? By the way, I bought the GB40 (7,000 J) about a year ago to ride around in the back of my Jeep. I finally got to use it to jump a friend's car last month, and it worked like a champ. I charge it every few months, even though it doesn't appear to lose much charge in that time, and I feel like I can rely on it when I drive off-grid from time to time. Much more useful than hauling jumper cables around.
After watching, I wanted to jump off a tall building, and scream all the way down.
Great Video, thumb up, make that 2 thumbs up :)
Nice watch, thanks. BTW, a Joule is (simply and also) a Watt * Second. ie, 1000 Joules = 1000 Watts for 1 second - OR - 1 Watt for 1000 seconds. Or anywhere in between.
Correct
Love the white board. Snap on Verus 12 v draws 60w + or - ?. Noco boost pac maybe 56 watts - without including the vehicle operating system for computers and lights the booster pack would not last one hour. How long on a dead battery , I look forward to your results. In my limited knowledge I have always used amp hours as not having the capability to maintain 12.6 volts for the rated time . The ratings in theory just haven't materialized for me, maybe it's just cheap batteries. 2000 amps haha , really - let's see in the next vid the conductor size of the cables and the real useable capacity compared to stating 2000 amps for an initial spike rating. Lithium batterys illegal to ship by CAN/USA postal service as they are rated as hazardous material and a fire hazard. Interesting to see how you load and measure the ratings shown on the Noco. Fantastic stuff Ivan...
Thanks Steve I'm glad you suffered through all that boring math haha Part 2 will be more fun I promise!
+motoYam82 Actually part 1 was great but this is youtube and your not suppose to think too much. LOL
Curious... I have a vehicle with a bad alternator (does not charge the battery). The vehicle battery is new and fully charged. Can one of these NOCO Boost packs be connected to the battery (leave it connected) and drive the vehicle to a repair shop to have a new alternator installed? I'm concerned that driving the vehicle under just battery power that it would die on the way to the shop, and that the boost pack would supply the additional power to keep the vehicle going so it would make it to the repair shop. Would that work?
Depends how far away the repair shop is! Make sure to start your drive with a fully charged battery :)
@@PineHollowAutoDiagnostics The battery would be fully charged, so that wouldn't be an issue. However, since you mentioned it, how far can one travcel on just battery power alone (a new, fully charged battery)? Repair shop(s), depending on which one I choose are either 6 miles away, or 14 miles away, both with several traffic lights along the way. Secondly, and more to the point of my first inquiry, can the boost pack act as an addition source of battery power if left connected to the battery?
@@HOG95fsxts yes the NOCO can be left on and act as an additional source. It's more about run time. I would say you could run for 30 minutes on a good battery and boost pack 👍
Lots of information. If you charge that battery back slower with the phone charger plug wouldn't it last longer than if you charge it fast with a cigarette lighter? Typically I have found that if I charge my phone in the car the battery doesn't last as long as if it's plugged into the wall.
Ivan, It would have far better to connect the the GB70 charging input to your bench power supply set to 13.8 or 14 volts. Most simple car battery chargers rectify the low voltage AC off of the transformer and feed that directly to the battery. Going to a higher current setting on your charger had heavier windings and likely a slightly higher voltage, but you were only charging on the peaks and you never got the 3 amp charge rate it can accept. If it was a smart charger that's even worse because because not only is that expecting a different battery chemestry, it's also not even talking to the battery directly. The GB70 is going to have a charge controller between that input and the lithium battery which regulates charging and protects the lithium battery.
Were Can I get a Pine Hollow Auto T shirts ?
Hello Ivan (Oh! Russian name). I guess 15700 J (3s) means that the booster can lose 15700 J for 3 seconds (look attentively - there written "3s"). Noco means - the booster can drop 15700/3= 5233 W/sec (for first 3 sec). Its appr 600 Amper nominal amperage. And I guess 600 Amps - isnt practical figure but just theoretical . What do you think about it ? I do reviews of Jumpstarters for russian-speak people and will soon to review Noco . I have a lot of questions to NOCO concerning amperage and the claimed ability to store and operate in the real cold
You really shouldn't charge the Jumpstarter pack with the lead acid battery charger. The pack needs smooth dc. The lead acid battery charger has a rectifier but no capacitors at the output. The output of the charger looks like this: upload.wikimedia.org/wikipedia/commons/thumb/a/a9/Gleichrichtwert-Sinus.svg/290px-Gleichrichtwert-Sinus.svg.png
I hope you know what I mean. Best regards from germany.
Good point. Didn't say anything about that in the owner's manual and nothing blew up so I think it will be OK :)
I also think it will be ok, it just doesn't charge properly. You could put a lead acid battery in parallel with the charger and the pack, this way it should charge faster.
I really like your videos. Thank you for them!
+Leroy Baker powering things.....like a car fridge,fan.....
Leroy Baker no i was wrong,you can buy an adapter that lets you plug in a cigarette socket,the socket that Ivan adapted whas saved from some place.
You lost me at HELLO 🤣🤣🤣🤣
I had smoke and sparks coming out of my ears. Oh my head.
I received this Genius GB 70 a couple of days ago. Attempted to charge it up using the USB port plugged into our household outlet the same as the way I charge my iPhone and it actually discharged the unit so it was weaker than the partial charging it came with. I’ve double checked the wiring to be sure it was in the IN port.
What am I doing wrong please.
Ok, so now I have a question. A motorcycle battery, and a car battery are both 12v, but the car battery has the ability to store more energy, for a longer crank time. Correct. But they're both still the same voltage, just a smaller capacity? Why could I not use a motorcycle battery to start a 350 Chevy?
Correct, the smaller battery stores less energy stored, and cannot provide enough cranking amps to turn over the V8 :)
It's all about surface area. The car battery has much larger plates than the motorcycle battery so it can deliver far more peak current. Car batteries are rated for several hundred cranking amps; the motorcycle battery far less. The reason the small capacity jump pack can start your car is because lithium batteries can deliver far higher currents than similarly sized lead acid batteries. The motorcycle battery may contain enough energy to start your car, but it can't deliver it fast enough to satisfy the power demand from the starter.
Dang S O N !!!
I was expecting :
A normal unboxing, let's charge it up & jump start my neighbors John Deere kind of thing.
Instead you stopped in the pasture & stumbled across a couple shrooms & decided to put on your labcoat, & give us a quantum analysis.
Well i had pause the video early into the third page of notes got a bottle of h2o & some edibles to help me channel your scientific vibe but i miscalculated my jewels.blew my load & now its time to recharge overnight.
You're way too much Ivan...NASA space program needs you :)
I am wondering how many Joules Ivan expended in making this video.
I have the large unit its a beast.. I have the heavy duty charger and charge it once a year..
3S is a common way to spec Li battery packs. Three cells in series.
The wall socket charging adapter is sold separately . It's approx. $40
How about the gb 150 for starting a 1995 chevy 6.5 Ltd. Engine
I tried to jump a commercial lawn mower that this do not work and I though it might be a defect. So I let my Toyota Tundra 5.7 drain to 6V, at least that is what the meter measure. It jump right up so I guess, it was to big for the lawm mower and there is a protection system somewhere. It is a great product.
Any 12V system should be the same fundamentally. Was the mower battery completely dead? If so, you need to press the "override" button to give it the juice :)
NOCO makes a 400 Milliamp 120vac to 12vdc charger 🔌 that plugs directly into the wall and the NOCO.
Long crank time diagnosis video next? :)
cool....so ummmm, is it a good jump starter?
Ivan I understand all of this but it still gave me a headache from HELL Best of luck friend Joe.
Ivan. I have a new Boost Pack. Is nice and PLUGS into AC to charge it. Think I bought it on E bay. Is a nice piece. The lack of an AC charger would be a TOTAL deal breaker. See you later.
Use a regulated variable dc bench power supply would provide the cleanest and highest output.
Kind of what I was thinking. That battery charger must have some major ripple. Or at least put a car or motorcycle battery across the terminals.
Now you're going to have me put a scope on the battery charger huh? I am curious now...
I agree. There should be a battery connected to the charger to smooth out ripple.
That indigo bunting in the background is kind of distracting, but they're beautiful birds!
My personal jump-starter is a A123 40Ah lifepo4 battery :p
Wall socket charger adapter : Noco Xgc4 56W Xgc Power Adapter
I need more white boards. I hated math in high school and collage but now that I can see a reason to apply it I'm going to get back into math....naw, I'm lying. But you did spark an interest again. Great stuff here Ivan. I do love to learn. :)
That is awesome, and was my top intent with this vid. Glad you enjoyed it! Math is the language of engineering and is very powerful indeed.
The GB70 has a 2 year life span especially if you keep it in your vehicle and is susceptible to large temperature changes it will stop charging the battery
take it appart i want to see battery label
Nice Part 1 review Ivan. Paul did a two-part review on the NB70 last year & it held up amazingly well especially under a cranking load with the battery disconnected & only connected to the GB70. He cranked it long enough several times that I thought he was going to start slinging solder so he gave it a good load test. I have one also & it has performed flawlessly. I also used it during reprogramming before I got my CTEK unit. I also bought the Rockford one from Eric O's review & it's in my wife's Traverse for emergencies however it gets used more to charge up their electronics & cell phones. For a little hillbilly testing watch ruclips.net/video/LNtaazuZz74/видео.html
My Gb150 lasted about a year. No NOCO ever again for me.
Audi d3 4,2 TDI batery 3 v, start no problem, first shoot!!!
I had my gb70 1 year used it 3 times. Light wouldn't shut off. And it also clicked when it was on... I sent it back few days ago..I assume I will have to pay to fix it.. I bought same one for my truck....it seems to work properly...I think the 1st one was bad...I took it to the store....oh it's working right...they don't know nothing
From the wall it should be charged using a micro USB charger
Charging though a wall socket via USB,,just takes too long,,(or life's too short) best bet is to buy is the option wall charger,,get it from Amozen for about £20,and it fits in with my battery carrying case,you got to have a case this bad boy is too heavy otherwise ,,regards
giving the basic numbers that this Box gives you there is a math problem. if the battery produces 55 watt hours which is it snowing work @ 12.5 volts and it says it makes 2000 amps that would mean it has to have a battery in it that a c rating 454. at this current time the very best battery produces 110 C for three seconds. to produce what it says you would need a battery that is 269 .09 whatt hours @ 18.18 amps with the c rating of 110 Jewels listing is irrelevant unless you know the longevity of the time that the energy is used.
The symbol for charge is Q not C.
Interesting the claimed amp hours and joules don't match.
Theat "Joules3S" claim was weird...maybe they mean Joules per start?
I HAVE A WALL CHARGER FOR MINE. YOU JUST HAVE TO DO A LITTLE RESEARCH AND YOU WILL FIND IT
Hi Ivan, I would like you to do this with 120V or 220V, so we know how much our stuff is consuming in the house as well. Thanks.
I loved it. Those of us that actually do diag on vehicles like to use our minds. I don't think this company realized who they were asking to do a review. Lol
kind of gave me flashbacks of when I was back in school . make me wanna grab some C batteries and Wingham at my fuckin tablet. like I used to do to my teachers chalkboard :-). but I didn't so I guess I'm all grown up now
He made a mistake. He multiplied 60 sec time 60 min. The 15700 joules marking on the device says for 3 sec or 3S. It should be 3 sec times 60 min. But it’s really 4.68 sec. So 4.68 second times 60 min times 56 watts equal approximately 15,700 joules.
I'm not sure who has the fuzzy math. The pack states its a 15700 joules pack, but your math at 34:01 says its a 201,600 joules pack. Hmm??

ah reminds me of college. No mains charger sucks
a watt = volt x amps 12 v x 10amps = 120 w
Charging from the wall is waaay faster. To bad it can't do that.
look what I have done now...turned your channel into real tool reviews L)
well...... unthil it is not biased it is ok:))
What flows in an electric circuit? Electrons. What is the charge on an electron? Negative. Which battery terminal has an excess of electrons? The negative terminal. Opposite charges attract. The negatively charged electrons are attracted to the positive terminal which has a shortage of electrons. This means that electricity in the form of electrons actually flows from negative to positive.
The definition of a positive and negative charge was established before we knew what was actually moving and before we knew what an atom was.
You got to be kidding, you expect me to watch all this brain damage and then to watch another video. Yeah right.
Just a minor note:
For a battery under load, engine off:
Electrons are negatively charged, and so are attracted to the positive end of a battery and repelled by the negative end. So when the battery is hooked up to something that lets the electrons flow through it, they flow FROM NEGATIVE TO POSITIVE. It doesn't matter if the automotive system is negative ground or positive ground (some old English cars).
Yup electrons are definitely negatively charged. However conventional current flow is from positive to negative...just the way you define it; the physics stays the same.
Should of done this on zOOM
Never use that kind of battery charger to charge it. It has a lithium battery! Not a acid battery. That charger isn’t right for it. You can also buy the wall charger separately. You also don’t want to charge them off a vehicle. It kills the jump packs.

No, "not that easy" :) in fact, wrong. You wrote: W = J but it has to be Ws =J
W =J/s
therefore 1 Wh = 3600 Ws= 3600s x (J/s) = 3600 J
therefore 1 Wh = 3600 J or 1 Ws = 1J which is very different from W = J which you wrote ;)
Sorry bad notation on my part. I meant (W = J/s) *s = J
No worries ;) My last math lesson was 25 years ago - but my teacher would literally kill every single one of us if we said things like "I'm gonna take X away from the left side and put it to the right..." -- then he would get in to a fit and say" equation" means EQUAL !!! If you take something away on the left and put it to the right it can never be equal again!! You always do the same operation to both sides! :) -- That had traumatised me so much that I still notice when someone sneaks in a change to one side of an equation but not to the other :) ;) He was a scary man ! :)
Baerchenization nujkik
I watched this whole fucking thing to find out what the cold cranking amps of the NOCO were. NO JOY!
From other, less scientific videos, I know that he thing will start my truck.
because they did not include a way to charge from AC I returned mine but have wondered why they did not. they don't even give you an AC to USB adapter. also, am I the only one who worries about the safety of lithium ion batteries?
ivan i hope you open it.... 2k amps through that cheesy cable?
they truly lie with those specifications... the use of "MAX" after the specs.
china crap made for the American market.
I know your a smart guy Ivan that's why I watch your channel I know and understand Ohm's law I even know and understand the pie chart while the Joule may not be obsolete it's not what we typically work with that's why you were converting it, not your best video
Very Scary
Many different types of batteries.
Is it really acceptable to charge a lithiom-ion battery or a lead-acid cell battery at 10amp or more?
NOTE: All coments based on 12v system.
If you add 12v at 10amp on charger and battery does not respond.......1amp and 9.9v (P = 9.9watt)
go to 50 amp and battery responds with 1.7amp and 11v (P = 18.7 watts)
Power to the battery has been increased by a factor of x5 (10 amp to 50 amp from 12v charger), but accepted power has only increased by a factor of x2 (9.9w to 18.7).
This is dangerous!
This vid needs a jump start. I gave up after 4 minutes of babble.
OVERPRICED
Not what I watch your channel for. - does the tool do what it is supposed to or not? Go start some vehicles with dead batteries and show me that it works.
Sorry to disappoint on this one. Just thought people might want to exercise their minds a bit instead of seeing sparks and smoke. That's coming up in part 2 :)
So don't watch the video dumb ass.
You are in the wrong profession need to go back to school
And get your teaching certificate don't watch RUclips to learn the break down amps to joules.
Figure out why the battery charger won't charge it at 3A but the cigarette lighter in the car will and you will actually be learning something.
That is a no brainer...
Battery chargers are not steady state DC output and therefore do not actually provide the NOCO on-board charge controller with the current/voltage that it expects.
Most battery chargers oupt a 120 Hz modified wave that has the negative portion clipped.
The inline meter is reading what the charge controller throttled the current to because it is sensing peak current and the inline meter is reading average DC current.
This would be very apparent if shown on a DC coupled oscilloscope.
Well, that's a fancy way of saying a battery charger isn't a power supply but, more info is better than none. I would have thought wonder boy from mysteryland would know that though.
Please let me know which points were not 100% accurate. I will do my best to address any questions in a follow-up video :)
+motoYam82
Ivan, check your YT channel private messaging for a message from me.
Do you realize that this is less Amp-Hours than a Milwaukee M18 battery pack for use in their cordless tools. I'm not very impressed.
Ha for how much it weighed they could have stuffed some more amp-hours in there!
