    Good option to keep in car under seat. Haven't had chance to use, but happy with the size and what it should be able to do.

    This works great and lasts for a good while. The only drawback is 1USB port vs 2 that competitor has.

    My friend's car would not start due to cold and needing a new battery. Unfortunately, her car was also parked in a way thar it would have been impossible to connect with another car to jump it so I let her borrow this. She said she loved it and has refused to return it to me so I might have to buy another one.

    This works for many applications. Obviously it can be used to charge your phone many times. What blew me away was that people also use it as a jumper pack for their cars. I haven't needed it for that yet but it's certainly a lot more portable than the average jumper pack!

    Never get stranded with a dead battery because you will be able to jumpstart yourself plus charge your cell phone. Great for charging if you camp or on the beach
