Bests & Worsts Reviews from Amazon

This has saved my butt 3 times while off road in my jeep. I drained my battery with lights and accessories. This device started my jeep instantly. It also charges my other devices and has a decent built in light. I was attracted to this because of price, power and size. It is the perfect size and weight to carry with you anywhere you go. My wife and daughter now have these in their cars as well. I will not leave the garage without this tool in the trunk of any of my cars. The charge lasts for a very long time. Be careful of cold weather though. bring it inside on cold nights. It will reduce the life of the charge if you don't. First hand experience with that.
