This is the 2nd different brand of car jump starter I’ve owned. This NOCO GB10 left the other in the dust! The NOCO GB10 couldn’t be any more easy nor convenient. My car had been sitting, and the battery was so dead, the remote locks didn’t even function. I hooked the NOCO GB10 up to the battery, powered it on, and pressed the jump button. Hopped in the car, turned the ignition, and easy peazy… she kicked right over! Took the NOCO GB10 off, and the car sputtered and shut down. So hooked back up, completed the sequence, and left it on until I hear the engine running without a gasp. Took it off, placed everything back in the NOCO GB10’s minimally profiled case, and off to the races!! If you EVER have to try and find yourself a Good Samaritan that’s kind enough to give you a jump start, and your cables are in the car as well, you’ll be so glad the NOCO GB10 was in your glovebox!! Highly Recommended!! A+++++

Says it's only rated for 4-liter engines. I jumped my girlfriend's V8 Dodge Durango and it started right up. Go to jump it now and it won't start. Has a new battery in it. Might be too much for this little thing. Wish it said on the box "Only rated for 4-liter engines". Disappointed in misleading description.

Very limited info on the outside of this box. It is actually model GB10. The mfr web site does not even list it or any spec’s. The box says 20 starts, the mfr web site says 2 starts per charge for the GB20, this is a GB10! The mfr web site says max jump capacity is 4.0 L gasoline engine for the GB20, once again this is only a GB10. I am not sure if this would jump start a 6cyl. engine. I don’t have enough info to take a chance with it. They lost me when I found out about the misleading info on the box that says 20 starts per charge. Maybe 2 on a 4 cyl engine, I don’t to take a chance.

I have used this jump box several times and it worked as promised. One car had a very low battery that a different jump box would not touch. The Noco has a bypass button which allows jumping batteries which have gone all the way to zero. The car started quickly thanks to the bypass feature even though its battery was completely dead. The club version of the Noco comes with a nice semi rigid zippered storage box which is nicer than the nylon bag which comes with other Noco units. There is a pocket at one end of the storage box, so I stashed a small USB charger in there. The build quality of this jump box is quite good and it seems to hold its charge pretty well between uses. It should probably be charged every three to six months to be sure it is ready to go when needed.

I have already used this twice. Once on my lawnmower and the next time was to help a lady with a dead battery. Highly recommend that every household have one. With all the computers and electronics in vehicles now, you don’t want to take the chance of messing your vehicle up.

not strong enough to start a battery that's not almost full.

Awesome. It outperform the older higher model GB40. I purchase another one for my other car.

Excellent. Charged NOCO UNIT. THEN USED IT . CHARED MY DEAD BATTERY RIGHT UP.

Lower output that prior model carried at Sam's Club

Love this booster it is small enough to take along with but strong enough to start any vehicle. Highly recommend this product.
