Rated 5 out of 5 by from Packs a Punch I bought the booster to have for motorcycle trips this summer. I wanted something small to take all just in case. I charged it and put it with my bike. Came home recently and left the lights on all night on the Nissan Frontier. That battery was Dead. The booster turned the truck over (slowly) but it did start. I'm very impressed and know it will start a motorcycle with a low battery from lights on when the bike is not running.

Rated 5 out of 5 by from Saved my Day I bought this unit a couple weeks ago and used to it to boost my snowmobile after it had been sitting in the extreme cold. It started up right away.

Rated 1 out of 5 by from keep your receipt i bought this 8 months ago and worked great for the summer BUT recently when i took it out of my trunk to use it, i noticed charge was down so went to the house and put it on charge -well i am still waiting for it to take a charge -and before some donut asks whether the plug had power, i checked that ( being an electrician) and tried it on different outlets as well - i have since read some other reviews saying that theirs wouldn't charge up either - also if it sits in your trunk and gets cold it won't boost - what is the point of that if you are picking your car up at the airport in the snow - run home and get your nice warm boost?? i think not -all in all it was wonderful when it worked but i need something i can count on, sorry

Rated 2 out of 5 by from Disappointed I bought this charger to boost my motorcycle battery however It never worked out. I even tried with the high amp option but that did not work. If it can’t start my motorcycle how this booster could start my car battery if I ever need to. I regret purchasing it.
