I have one of these and it is pretty darn good, will start a V8 30 times and a 4 &6 cyl about 50 times. It has ports for charging any electronics like lap top, phones (will charge a phone about 3 times), I-pods etc. 300 odd CC and a 600 CC boost plus it has a bright light on it which can go into SOS mode for emergency's. Also you don't even need to have a battery to jump start, I wind over engines out on the bench with it. Takes a wall plug or a car adaptor to charge up.
