Might be a good idea - I thought the video was right on point

[@krazyray2000]

In my opinion, you could have gotten more starts from the GB40 if you had read the instructions. Quote "Do not attempt more than five (5) consecutive jump starts within a fifteen (15) minute period. Allow the GB40 to rest for fifteen (15) minutes before attempting to jump start the vehicle again." The way you were going at it with the starting and stopping either 1) It caused the GB40 to fault thus not allowing power to flow. It has built in protections Or 2) as @Muhannad Ammar stated "the car quit turning over, not because of Noco Booster but because the starter internal armature burned out!!!" I have seen this happen with poorly trained aaa techs who are to impatient when trying to jump someone. Best suggestion I can make for anyone using a jump booster.... Read the instruction. They are written for a reason.

[@Kitearmy]

Good suggestion

[@kelvenguard]

NO JOKE... I got ONE Boost on my 2.5L 2001 Subaru Outback then had to recharge it, Subaru stalled moving would not Boost again had to start the truck NOV -2 outside... I've boosted about 5 vehicles in the last 2 weeks and keep it fully charged WORKED GREAT ON ONE BOOST... SO... did I get a LEMON ... 1 BOOST ??? BOX says 20 BOOSTS per charge LOLOLOLOLOLOLOL That's the JOKE

[@rctjacksonville]

The booster is also not designed to start the car without the battery connected. Even a dead battery has around 3 MA of power which is enough to keep the booster from going into no start mode. I have one of these and once jump 18 vehicles at an auto auction, granted they were not all completely dead. I recommend the booster for all my friends.

Where can ibuy noco gb 40

[@1badpete999]

If you use them like here in Canada with subzero weather as the norm believe me the cool of time is way faster ,I own a GB40 and and use it on a small pickup truck with a 4L 6 cylinders and this thing can boost it sitting in a snowbank more than 4 times ,Noco products are a dying breed of quality products just their packaging shows that this company care about their name and quality of their products ,these booster are like a small brick with thick plastic something we rarely see coming from china nowadays and the quality of their plugs and wires is top notch , and they have a complete line of adaptors, cigaret lighter adaptors ,cable extension, that you can also buy separately, i've also purchased from Noco their Genius Gen1 battery maintainer your can mount permanently under the hood totally waterproof ( even recommended for boats batteries ) you just plug and forget ! Today's cars electronic pull all kind of juice out off our battery even in the turned off state, plus batteries are not what they used to be with all kind of ecological restriction and the use of powder acid instead of the liquid one used before,these new batteries goes bad at the blink of the eye if left to long discharged !

Had you left the battery terminals on and waited for a minute or two, that first jump box would have probably started the car. That being said, 400 amps isn't usually enough to start any engine, by itself. Its called a booster/jump box for a reason, it boosts/augments the existing voltage in a single battery system.

@@Kitearmy Yes but what you failed to mention is that the GB40 won't do a thing with a dead battery nor using it while having the battery disconnected UNLESS the override mode is used.

I will try something else before getting another battery and wish I knew where the cables are for my other boaster which I got about 5 years ago.

I ran my dead mini van battery for a few days of the gb40. The battery would not hold a charge but while driving I could charge the gb40 through usb. It doesn't discharge when the car is stopped either. It was faster than jumpstarting with virtually no wait. By the time I walked back to the driver seath the car would start.

[@daveflynn7955]

Totally agree with ya there. Aggravates me.

[@clange50]

If you have an alternator that works (aka just a drained/dead battery), these work beautifully. Even if the battery is totally dead, getting it running is going to get the alternator providing the needed power. You're good. If the alternator dies, it may not matter jumping the car. The alternator may not be creating enough power to keep the computer running. Ask me how I know. I've had 3 damn alternators die in the last year, stranding me. The gb40 could jump it 3, 4, 5 times, car wouldn't drive.

Have to wonder, what car built in the past 15 years that does not cut off the power after the lights (door or headlights) are left on after so many minutes? Even 04 models (at least Jeep) did this.

[@jerryg50]

Normally, a car engine system in good condition should start on the first or second shot. When jump starting the battery would be connected, and thus, being a lead-acid battery the power left in the battery would be adding with the power from the portable booster. Once the car is started you remove the booster unit, and close the hood. When inside of the car you can use the 12 Volt utility socket with the USB type charger to top up the Lithium battery in the booster unit. The power would be coming from the alternator, unless the alternator is not working, and thus the car will not go very far on a dead battery. I have the GB40 booster. I just recently got the GB70. I wanted the larger one because it has a 12 Volt utility socket that I use to run an air pump, or other 12 Volt type devices.

[@Kitearmy]

Thanks for the comment. I should have gone with the larger battery :(

Be advised that these things don't hold a charge for very long. I received mine about 6 months ago, charged it to full capacity and left it in the trunk of my car. When my battery died I decided to give it a try. To my chagrin, the damn thing lost 75 percent of its charge just sitting in the trunk. I have had similar issues with other lithium chargers so I'm wondering if it's just a characteristic of the genre. The NOCO does come with a USB charging cable and a cigarette lighter adapter so I suppose I could just leave it on constant charge in my car but that kind of defeats the purpose in my opinion. This thing is also kind of expensive. You can buy chargers with much more charging amps (albeit, much larger in size) at your local Walmart for about half the price.

nice one thanks buddy

[@Kitearmy]

Cool

[@moisescpr]

Thank you for the review. This was helpful.

[@Kitearmy]

Glad you liked it...very useful!

[@GrimYak]

You and i have different definitions of a truck

[@Kitearmy]

What you don't consider a Toyota Prius a truck?

[@ericschmidt1987]

Isn’t that a Subaru? It looks like it.

[@juliogonzo2718]

I'm actually surprised it started without the battery. I bought the gb70 and returned it as it would not turn over my old diesel pickup I used to have without batteries connected, despite claiming to start up to 6L diesel (it was 5.9L). I have the gb40 which I have used many times and it has trouble with anything bigger then a 4 cyl in extreme cold (below -20°c)with warm booster. Warmer temps it does alright. I still have a lead acid booster as well and I think it has a little more oomph. Thinking of connecting the two permanently to make a hybrid booster but that might let the smoke out I'm worried

[@Kitearmy]

Sounds like mad science stuff - With big engines I think the lead batteries do a better job

[@juliogonzo2718]

@@Kitearmy yeah my one buddy has called me a mad scientist a few times. I have hooked both boosters to a battery at once and it didn't blow up. I'm tempted to try it. At worst it'll smoke my 4 yr old boost pack. I just put a new sla battery in it today. Amputated the stupid air compressor hanging on the back of it too

[@Kitearmy]

Sounds like my idea of fun. Just and FYI be careful around lead acid batteries - when I was a kid 1 blew up in my fathers face - something about off-gassing. Not sure if that is still a real problem.

[@juliogonzo2718]

@@Kitearmy trust me I know! I had one explode once. I am a tow truck driver, boosted 1000's of batteries without incident before it happened. It was a CN hirail pickup. Boosted it once and he made it ten minutes down the road and parked in a grocery store parking lot. I boosted it again to move it out of the spot to make it easier to access so I could tow it. As soon as driver turned key to start the whole top blew off the battery. I was 4' away and got one little drop of acid on my arm that was it. Should have bought a lottery ticket lol

[@Kitearmy]

Mate...so glad you didn't hurt. Your just out there trying to earn a living. So if anyone knows boosters it's you. Thanks for the comment

[@user-wo7rp6bc6t]

great review. when it's super cold any of those jumper wouldn't cut it.

[@Kitearmy]

I would love to do the same test in the cold

[@905nite]

The NOCO GB 40 works for me in Toronto when the weather is -15 Degrees Celsius.

[@Kitearmy]

I bet that is true...This was a worst case scenario without the car battery connected.

[@JayJLucas]

Started my truck at -30c (wasn’t plugged in overnight) no problem

[@richg0404]

@@JayJLucas the test would be to store the battery pack in the cold and then see if it would start the car. Most people would probably just leave it in the car until they need it.

handy to have around they make a bigger one too like that

No doubt. I wonder why tow truck drivers don't like these :)

i know id have one of the biggest ones with me all the time

Your supposed to keep cables on so power pack can use the little juice power it up,no ome takes the cables off,SHHHHEEEEZ man what are you thinking the negative off, your car has to reboot and re sync the memory if dis connected.

[@Kitearmy]

Ok. Thought this was obvious but my battery was not really dead. Wanted to demonstrate the power of each pack.

[@Nacturnal702]

@@Kitearmy , yes but i was checking all over the web and reviews from people to see how good the GB40 was and its one of the best so far,, And thanks Great video

Diesel car you can forget it do not work on BMW 520d with the car battery low .

Diesel engines in the cold would be hard to start.

[@CadiKane]

Returning mine today. It’s not meant to be used daily only once a month maybe

[@Kitearmy]

No probably not - I think what you are looking for is called a new car battery

[@CadiKane]

Kite Army no what you are looking for is a dumb person to act smart to, I’m not , I do roadside assistance and this unit did not hold up like the big ones

[@Kitearmy]

@@CadiKane Sure - this is not made for professional use. As you notes, the battery is just too small.

A better test would have been trying to jump Different 🚗s with diff types of engines. Ex: 4cl 6cl V8, etc. It would have started 2 Max.

[@Johnny-vu7db]

I do jump starting for a living with a properly modified truck. Twice, I have had different customers call me for a jump after the precious GB40 they keep in the trunk for emergencies failed to start their 4cyl car. I double checked and the GBs were, indeed, fully charged. This isnt a review or complaint btw, I just know they're good for my business because they don't work when they're need the most. Keep buying them and pay the jump start guy anyways. Cheers!

[@Kitearmy]

Nothing is fool proof - mine saved me twice now - 2 less tow truck calls..thank you

[@fortyoneshades]

Mine has worked several times now and saved me from calling arrogant know-it-alls that do jump starting for a living

[@Kitearmy]

I love that feeling - like you cheated the system and saved $100 per jump

[@n8zee]

Johnny5 I have used mine twice on other peoples cars, and it worked fine.

[@Kitearmy]

cheap insurance

[@michaeld2176]

Booster products are essentially a 2nd battery source. Leave this product outside in your car when it is freezing and it will not function properly and the fault lies squarely on users . During freezing temp times bring it with you. Never ever leave it outside during freezing temperatures. What if you leave your labtop outside during a minus 25 night. In the morning try starting it up and it wont work properly.

[@Kitearmy]

Good point

[@zumik83]

What if you leave your ECU (that is essentially a tiny laptop - Engine control unit) outside during a minus 25 night ? ... WHAT WILL HAPPEN ??? nothing will happen to it ... as well as nothing will happen to many other electronics in your car ... and they are far more expensive and sensible parts that a NOCO jumper. C'mon people...

[@Kitearmy]

I think the cold will reduce the boost performance of this pack

[@zumik83]

I get it, but the car won't look at the temperature and decide, well, it's too cold today, I will start your car now, and give you trouble when it's wormer.

[@Kitearmy]

my car is cranky like that :) Actually it's the driver who hates to start on cold days.

Your door left open over night that usually means some broke into your car not a dead battery lol

Or absent minded kids

[@turbo3492]

You do realise the car battery should be connected before using the jump starter.Failure to set it up this way you risk causing serious damage to the car's computer.

[@Kitearmy]

that's why I couldn't keep my car running ;)

[@zardozqq]

haha i had the gb40 and my alternaitor died so then i had to keep driving home and my battry finally died, so i jump started it with the gb40l a few times until the battery wqas dead...so i jusst left the gb40 hooked up and drove it a mile to make it home wow now that was impressive

almost good , but you need to yell just a bit louder and you will be on Killmer level

[@Kitearmy]

I can't hear you???

[@slasher7555]

lithium batteries are not meant to be recharged from the alternator Unlike your lead acid car battery.. Doing this test over and over will actually ruin your jump pack.. it also proves nothing since they're supposed to aid your battery not replace your battery.

[@Kitearmy]

That's right slasher....it does prove that the Noco gb40 has enough power to turn over my engine without any battery assist.

[@slasher7555]

Just because it can, doesn't mean you should. The bypass button (which ignores the 2v safety protocol and makes it possible to start completely dead batteries with a full 12v circuit) isn't meant to replace the battery completely. It was a gimmick that Noco said they could do it.. but its not recommended. The Feedback from the Alternator charging system that would normally start charging your car battery can and will damage the lithium ion jump pack especially if done repetitively or left connected for longer than a few seconds after the jump.. which can either stop it from working completely.. or damage it in such a way it will never be as powerful again making the peak amperage lower than advertised. I'd hate to see someone watch a video like this and believe its an ok thing to do and then wonder why their jump pack no longer works or as efficiently.

[@Kitearmy]

point accepted. youtube is riddled with stupid stuff that people do...add this to the pile. It's probably why the pack quit functioning after the 9th start.

[@Robsbrd99]

slasher7555 That's the main purpose of these jumpers.To start a car when the battery is dead. I have one for my 4runner and I started the truck directly off the pack to be sure i got what I paid for.

[@slasher7555]

Robsbrd99 when battery is dead. Not with out a battery even attached.
