    Awesome
    5 Stars
    Awesome
    Easy to use. Great quality for a fast charge & informative/easy to use display. My work car barely started today due to company gps attached & 2-week sit time over Christmas/New Year holiday vacation. I hooked up the charger, set it for 12v cold (due to 30F condition) & it started its cycle, showing that I was at 25% even after a drive to the store & back. After 15 minutes I am more than 50% charged & on my way to a healthybattery state.Suggestion - if you plan to use this as a starter or you plan to park the charger anywhere other than on top of the block of your engine while in use, you will need the 10' extension. The clamp jaws are good quality but inly have about 6"leads and the mating cord end only extends about 2' from the charger.I also wish there was a storage box for the charger & attachments.
