I bought this boost plus when my battery was going bad. I would hook it up to instantly start my car. I am surprised on how good it worked. After each use I would charge it back up in my car going down the road so I never let it run down... I was expecting the worse case scenario at any time. My car battery finally went to the worse, it couldn't hold any charge.this booster always worked instantly. Just hooked it up, turned it on and the car would start right up. I bought a battery for my car and keep this boost plus in my car for myself and others in the time of need. Besides how good it works and its small size to store and carry, you can charge in your car so you are never with out it when you need it.If you are looking to buy you won't go wrong with this.. I do have to mention that the charging cord that came with it didn't work so I called the company to get one that works. When I called I had to be persistent that I needed one that worked from them. I was told that I could buy one anywhere or take it back to the store that I bought it from for a exchange. Reading other reviews the charging cord that comes with them are the biggest complaints....... I would recommend buying this to any one It got me back one the road fast over and over again easily.

I bought this in case my snowmobile went dead in Maine. It couldn’t jump an 800 skidoo let alone a 6.0L gas truck like it says. I will be returning it.
