  • Good powerful charger!
This charger appears to work well charging a battery and I know that if I need to jump start a car this charger will do that as well.

  • Eh...
I recently had a dead battery as well as a blown tire and when I saw this on the Vine I was really excited. Some of the previous reviews made me nervous so my dad husband and I used it on an old battery that was almost drained rather than wait for my car battery (or theirs) to die again and perhaps be crap out of luck. It’s small and the cord is really short. So note to self you need to have an extension cord. In addition this is NOT fully weather proof so if you car dies in the rain, snow etc you’re out of luck. Make sure you also get it for the proper battery power otherwise you’ll be out of luck. For a quick charge or broken down on the side of the road I’m not sure if this is the best. You may be able to get a boost home if you charge it for a bit, but as others have mentioned you do need close to 24 hours to charge a mostly or fully dead battery. The product itself also isn’t intuitive and if we hadn’t had my dad there (who has multiple chargers and gadgets) this wouldn’t have been near as seamless. I’ll update if there’s anything else or if the unit stops working. ... show more
