This is a listing for a PHILIPS car portable battery jump starter. I haven't had a chance to use it in a real emergency, but it's practically new, as I only tested it on my own car to confirm it works. I fully charged it in mid-May, and it started my car with one try, so it seems to have very little self-discharge, and the condition is quite good. I removed my car's battery and connected the terminals, and the engine started immediately, so it's a great product. I'm selling this one because I bought a different type. It was kept in its dedicated case, so there are no noticeable scratches or minor blemishes, and it's in very clean condition. Please be assured that there are no smokers or pets.
