This booster is a life saver very happy to have purchased it knowing that I have it and can be used whenever possible.

I was hesitant at first but works great. I use it to jump off my riding lawnmower. I also like that I can charge my phones and stuff with it.

100% fire hazards. These things are insanely dangerous! Had one catch fire in my car! Out of 5 units we have had 5 go bad in 6 months.

Has worked great for me. Keep it in my truck and holds a charge for a long time. It is one made just for Sam's Club but is most like the GB20 on NOCO website.

Not worth it. You won’t be able to charge pickup trucks. Even small vehicles you can only jump once then you have to put it back in charge to be full again.

Had mine about 9 months now and love it. I keep it in my truck for emergencies. Also works well for charging cell phones on the go. Used it a few times on the lawn mower and a couple times on my 4 wheel atv and gas golf cart. Bought one for my daughter to keep in her car as a measure of security.

Bought this item a few day's ago at our local Sam's Club and have not had an occasion to use it yet but I am sure it works fine. The reason for the 3 star rating is that when I got it home and opened the sealed package it was in there were a couple items missing that should have been included: 1) USB Charging Cable and 2) User Guide. So I had to buy a USB Charging Cable (which cost me an additional $7) and had to download the User Guide from the manufacturer's website.

But I want more power for business purpose. This is awesome I did turn on my SUV 8 cil. with no battery on it just to move it a little bet I will buy a more power kind. 5 stars GB10 is good for small engine but if you want more power you can buy more, different model.

Works wonderful starts right away one time.

already used it. Worked great but the the clamps could have more bite.
