    • Great Product & Problem Solver & Safety Insurance too!
Style: 1000 Amp
I'm one guy working at home with 3 cars.............. o need to commute or do a lot of driving. My car batteries started dying because I wasn't driving them enough. I bought jumper cables which was fine but decided to give thee a go based on a friend's recommendation. Boom! Problem solved! Much easier to use. The unit retains charge for MONTHS, and you don't need another car to jump from. Super easy to use........... glad I bought this!!! I bought another one for my son who lives up north in a much colder climate where getting stranded alone could be dangerous. ... show more

    • THIS TRULY WILL BECOME A LIFE SAVER - RELIABLE
Style: 1000 Amp
After 6 months stored in a hot car it was at 99%. Great product that comes with a real light to see in the dark with flashing mode, too. If your car/truck/ battery is over 2 years old, this is a must have as it will start you up until you can buy a battery.

    • great jumper
Style: 1000 Amp
i bought it for my motorcycle, it will work on cars as well, but i bought it to carry on my adventure biking trips, it has already saved me, i was testing my heated gear to see how much amperage i could pull from the stator without killing my battery, and i took it just a but too far, with full heat, heated grips, heated seat, high beams, aux lights and add on fog lights. when i stopped to get gas, my battery had dropped to 11.5 which during cranking went to 10.4 which is not enough to get the computer to turn on.. hooked up the jumper and it ripped right over.. also i can use it as a mobile 12v power bank to heat my heated riding gear away from the bike... and has usb charging ports for other stuff, and the led light is handy as well.. it will be great insurance when im in the middle of nowhere on the bike. ... show more

    • Works great!
Style: 1000 Amp
I bought this a couple of years ago and have never used it, until yesterday. I need a new car battery, but haven't had time. My battery will die if I don't drive the car every couple of days. I finally remembered that I have this, so charged it up and threw it in my car. Yesterday, my car wouldn't start, so I hooked this up (I keep it charged and it holds a charge for a very long time) and it worked like a charm. No more asking neighbors or strangers for a jump. Very glad I have it. ... show more
