Here is the factory description: "The GB30 is an ultra-portable, lightweight and compact lithium-ion jump starter for 12-volt batteries. With it, you can safely jump start a dead battery in seconds - up to 20 times on a single charge. It's mistake-proof, making it safe for anyone to use and features spark-proof technology, as well as reverse polarity protection. The GB30 lithium jump starter integrates with a high-output dual LED flashlight with 7 light modes, holds its charge for up to one year and features a USB battery pack for recharging personal devices on the go. It's suitable for use on vehicles up to 6 liters (6000cc), such as a car, boat, truck, RV, motorcycle, ATV, lawn mower and more. Truly, we've designed the GB30 to be the ultimate emergency roadside tool."

GB 30.......u need the GB 70 for that truck bro.......the same thing happend to me... the one you have is for 4 and 6 cylindes it says for big v 8s but it wont do it.

[@FishFind3000]

Sounds like NOCO is a NO GO!

[@toddh6234]

I don't think your unit ever detected the battery. You are suppose to fully charge these things before you use them for the first time. In your video around the 5:25 mark, you connected the unit and the green light blinks. All of those power lights are suppose to cycle back and forth when properly connected and detecting a battery. The battery has to have a certain level of charge left in it, in order for the unit to detect it. If the charge is below that value (I'm sure your was in those conditions) you have to press that override button, wait a minute or two and then try to start your vehicle. They have a demo on their website showing a truck being started in -32 degrees celsius. I have one and it hasn't failed me yet. Anyone looking to buy one this I recommend waiting for the blackfriday sales. You can save about $60.

[@Lugnutfilms]

T- Daddy It clearly states at 1:41 that the product was allowed to fully charge first. There was no one who wanted this device to work more then us. We gave it every opportunity under the cold conditions. If you are want to start an engine with a dead battery in sub zero temps then we don't recommend this. It can't replace a battery charger in those conditions. For almost every other application I would still not hesitate to recommend this product. It is a very innovative device. BUT...I will say this. I was able to obtain a newer model of the GB30 that will be hitting the shelves in April. We hope to review it soon.

[@garysmart1]

did you do the manual override its say you need to do manual override if battery really low

[@alexshillinglaw3112]

I agree with this review. I left my NOCO in my truck just incase but when it came time to use it (in -40C mind you), it would not turn over the vehicle fast enough to start it.

[@n2o4me]

Still very impressive that it would turn over being that cold ! Did you guys try the override feature as well ? Sometimes all you can do is heat the engine , the oil is like molasses .

[@TheSimplecanadian]

you should probably try the gb40 model not the smaller lighter duty gb30 model. Yes it says it can jumpstart up to 6L gas engine.. "Up to..." I'm sure it would work if it wasn't cold. I am personally going to buy the gb 70 HD model for boosting my 3.0L V6 ford escape and to help anyone else out this winter. The gb 30 has somethting like 5500 starting jules where as the gb 70 has 20 000 starting jules. 4 times as powerful. So ya maybe next just try it with one of the more powerful units. Otherwise good real world test.

[@JazzFunkSouldier]

did you use the bypass button ? for flat flat Batts

[@garysmart1]

+JazzFunkSouldier yeah i think he didn't do the manual over ride

[@fortifier69]

+JazzFunkSouldier ....that was a good point JFS, as I believe it would have possibly started. An oversight on their part

[@JazzFunkSouldier]

(Y)

[@Lugnutfilms]

Yes

[@lolilando]

I live in Edmonton Alberta, last January my battery decided not to work. I friend brought one of those little booster and Nope!! -40 degrees. And didn’t want to. I wonder if there is one of those that really works with Low temperatures

[@Perplexer1]

Although it says it can be used on 6.0 liter gasoline engines, this isn't really true, at least not in cold weather. This is the old model now though so I wonder if the current GB40 model is any better. Still, it just shows you that you should take the advertised capabilities with a grain of salt. If it's rated for y 6L engine and yours is very close to that, you really better buy a "bigger" model which can handle 8L engines. Nice real-world test overall.

[@TheBearsButt]

Thanks for the honest review and the video to prove it. I am looking to buy something that will allow my son to start his truck in exactly the same situation you guys have going on in this video! Thanks you!

[@oneisnone7350]

I had a GB30 and it failed me twice. One time the battery was low, so looks like it has to be recharged every few months to maintain a decent level. For that reason I gave it another chance. About two years later today, it was about 75% and wouldn’t get the car started. Fail fail fail.

[@momo1883]

guys :) thanks for honest opinion finally some good test on the YT :)

[@dominique___1980]

Answers a load of questions from other videos. THanks, lads!

[@dalesheldoniii7451]

U need the gb 150 model of that it has 4000 instead of yours only 700 or 2000 amp

[@nathanshiba6866]

An honest review of a Li-Ion battery in the cold. Good for you.

[@toecutter7683]

Maybe good for a small engine or motorcycle

[@TnTTyler]

It appears you opened the package and tried to use it without charging it first. Manual states it needs to be charged before the first use.

[@TnTTyler]

You can also connect it to the battery and wait 5-10 mins and then give it a try. The one time it didn't work for me I just left it connected for 10 mins and the vehicle fired right up.

[@Lugnutfilms]

TnTTyler It clearly states at 1:41 that the product was allowed a full charge first. There was no one who wanted this device to work more then us. We gave it every opportunity under the cold conditions. If you are wanted to start an engine with a dead battery in sub zero temps. we don't recommend this. It can't replace a battery charger in those conditions. For almost every other application I would still not hesitate to recommend this product. It is a very innovative device.

[@TnTTyler]

My apologies for missing that, I haven't seen the behavior you have. I did have it fail to start a 3.0L V6 in a Jaguar once, and just let it sit for 5 minutes, and after that time it started up. Temperature was -15c

[@Lugnutfilms]

TnTTyler Yes...this was -17c and a big engine. Great product though. Really cool idea.

[@kizzer1981]

I live in Canada and have tried 3 of these little booster packs. None of them have enough juice to crank my Nissan Titan (V8) in sub zero temps. I’ve given up on them altogether and wouldn’t recommend one unless you have a backup plan!

[@markgilbert8389]

I didn't see you check the battery voltage. It's my understanding that for your booster to work properly the battery should have a 2 volt minimum charge to begin with. The booster may not work with a completely dead battery.

[@Lugnutfilms]

The battery was charged. I think the issue was how cold the truck was.

[@mr_nice.]

hahaha.....apparently my testing of one of these "no serious brand" boosters starting a 1.6L engine in -1C was a walk in the park compared to -14F for this 5.4L. :) :) :)

[@2mail2mail99]

I really enjoyed watching this show, may be there is some mistake or may be not !! however, your record inspires many people to be careful before they buy such tool .................thank you

[@tonioyendis4464]

From looking at the lights on your gb30, it didn't appear to be fully charged. Thats why it didn't work.

[@Lugnutfilms]

It was fully charged as was stated in the video.

[@JJamiah]

I have a Halo Bolt and it works fantastic. You might want to try that unit instead. :) great review.

[@johnwaller9097]

I wonder weather or not you had a dead cell in your battery. You would have found out if a battery tester was used. not knocking your review but pointing out an important variable.

[@arthursilva2005]

Have you guys ever tried any other units to see how they work in this scenario? I'm curious if the one you tried is just junk or if it's something that these Lithuim Ion units just really can't handle, at least not for such a large motor. I was thinking of getting one for my R1 to use when it's like 28 degrees F out at night and I"m leaving work. Thing usually won't start in those conditions even though the battery is pretty much brand new. Just too small of a battery for the motor compression and temps.

[@ekop1778]

HAD ONE OF THESE JUNK THINGS FROM AMAZON BROKE DIDNT LAST WEEK USE THAT BIG JUMPER PACK FOR 100 DOLLARS NOT THESE TINY SHITTY PACKS

[@iinstallrva]

Honest review.

[@kendallworks5035]

My GB30 was 100% charged and it can't start my Ford F-250 V10. 6.8L. Was pretty pathetic. It says its rated to start a 6.0L, maybe in the summer with all the right conditions. Not something I would rely on that's for sure.

[@kendallworks5035]

Yeah, the GB30 was a christmas gift... If I was to pick on of these units, I wouldn't buy a NOCO.

[@kendallworks5035]

I also own a 5.7L ls1 firebird, that car has been sitting in a garage all winter and it wont turn that car over either. Wife ownes a 6.0L escalade, doubtful it will do anything for that either. NOCO = NO GO.

[@viddeh8010]

ha ha tnx from cold Scandinavia - u rock

[@GuideauxPelagos]

Hilarious great video guys (and informative)!

[@JKatPoinciana]

Good honest review. Thanks.

[@waynedang1605]

appreciate it for being honest.. great video

[@03065283464]

thanxxx great and honest review ... appreciated ...

[@alisaleh4758]

Can this start a scania or volvo truck ?

[@phillydawg1313]

Numb nuts had the headlights on! Watch the video, the headlights were flashing every time it cranked. If there was a dead short in the battery they could have disconnected the truck battery and ran it just on the GB30 only. I know because I've done it!

[@Lugnutfilms]

If you would have a taken a few min to read the other comments we have made you would have found out that an auto light switch is required in our location. You can't turn the lights off. The moment you turn the key they come on. The reason it could not crank is because it was to cold. That's it plain and simple. When it is that cold with no block heater on the engine it just does not have power. We did all we could to make it work. We even disconnected the battery all together, used the override and it still could not do it. On another note. When spring time came it had no problem cranking that truck with the battery disconnected. It's a nice unit. Just not a solution for extreme cold weather starts.

[@stevenwilliamson2025]

All their units lie greatly about amps.they are dishonest..Several utubers have tested them and the amp ratings are quadrupled or more.

[@Happy-Me.]

Why are you starting you vehicle with the light on?

[@Lugnutfilms]

We have responded to this a few times. Some places require and auto light switch. This truck has that. So it is impossible to start the vehicle with the lights off.

[@Happy-Me.]

Cheers from the UK

[@tomallen100]

Lithium ion batteries don't do well in cold.

[@martinst-pierre959]

First you did not try the bypass feature, second you did not choose the right charger for the job, you should have got a GB40 which is a 1000 amps 7000 Joules, This is a truck dude !!! . or maybe better, use a GB70, 2000 amps

[@Lugnutfilms]

+Martin St-Pierre we did try the bypass feature. Not to mention that on the package NOCO claimed that it would start a 6L engine. I feel like we were being fair. I don't really blame the unit as much as I do the cold. I think in normal conditions it would work fine. This was a cold weather test.

[@aminkhashm]

guys you should use override to make it work. ☺ please read instruction manual

[@Lugnutfilms]

We tried override. It was just to cold.

[@quagmire94]

that brand promisses 1000 amps but only does like 150 amps . and in cold less then 50. that will start Nothing.

[@fknows1]

all I can say if these things are so good, and work as well as they claim. why do mechanics and workshops(like myself) spend hundreds of dollars on equipment to be able to go out and jump start a car when we all could just go and buy one of these for a fraction of the cost

[@martinst-pierre959]

This is for occasional jump starts, not everyday heavy duty jump start equipment like the ones found on workshops that cost thousand of dollars. The efficiency of those little jump start packs is 90 % better than those found on workshops, but are not made for everyday use.

[@fknows1]

wrong every day jump starters mechanics and workshops use do not cost thousand of dollars. few to several hundred dollars yes.

[@scottalmeida]

Good vid

[@netflix8811]

it appears that you did not push the power button on the noco unit,,the led lights were not flashing,,, check out there u tube channel,,, u might need to redo your review

[@netflix8811]

never mind my bad

[@just1lifexx11]

yessss. i agree with you guyss.. that small thing is a waste of money.. 5 turn, no more juice.. hahahahah.. spit on it a throw away in the toile... ahhahaha

[@leapfrog4561]

so its too small?

[@just1lifexx11]

those are deep cycle battery, also call wheelchair battery.. very high maintain, work well, in cold, or hot wheather!! but they charge slow, like old lady)), if each cell drop to below 3.6v-- your screw.. buy one! you needed- talk to wheelchair people.. anyways I have 2, battery. later

[@leapfrog4561]

VANflawless flawlessNIXION so old ladies charge slow?

[@nitramretep]

NOCO is selling a lot of these units, and others, to people with no idea how over rated and outright misleading the units specifications are. It takes up to 14 hours to charge, the internal soldering of the wiring is a nightmare if not outright dangerous. These units are good for 5-6 cold engine starts, after that the battery is never the same. Good luck using this fine piece of Chinese manufacturing and shoddy quality. NOCO has managed to get away with selling promises over performance. Try that unit after using it 5-6 times and after it has sat in the cold for several days.

[@officialhydracor7391]

Ave fanboy ay? That guy is biased as fuck, these things work better than he states

[@nitramretep]

You sound like a shill for NOCO. Don't bother responding.

[@Musicizmyremedy]

Peter M mm it only took me 3 hours to get a full charge

[@nitramretep]

Oh really that's wonderful!

[@naderdana0]

I have one, I believe it is garbage.
