    • Well worth the money!
Size: 4000A
Works great. Make sure it's at least half charged and it will start a dead car (or small truck, I've done it) pretty easily. Light as a feather compared to the old jump packs. Also can be used to charge phones, tablets, etc. with pretty quick ports.

This is such a great product at a competitive price point, especially if you like to be prepared. With this portable jumper starter, you’re able to jumpstart your car without needing to rely on others for help. Works perfectly as described, and is small and portable. Comes in a nice bag that you can leave in your trunk that does not take up any space at all. Would make the perfect gift for any adult! ... show more

    • Rigged to fall apart when it is too late to return
Size: 4000A
Immediately after my return window closed, this item began to fall apart. The ports are not soldered to the circuit board, they are held in place by the case, which is fastened together with screws of a certain metal that reacts with electricity because they slowly unscrewed themselves every time I used the box. Also my car battery and alternator are now broken, I think this jumper box was rigged to switch polarity. I really wish I could get my money back so I can get a different car jumper or at least a replacement that I can do preventative soldering right away before the issues begin. You are better off going with a different option if you are contemplating buying this. ... show more
