Enerplex Jumpr Stack 6

We haven’t spent as much time with this model as some of the other chargers in this article, but we’ve taken a rapid liking to this simple and intelligently designed device. If you’re primarily charging your phone, this is the power bank for you. The Stack 6 has an attached iPhone cable that ingeniously tucks away into the hard drive-sized battery, so you don’t need to worry about tangling cords or misplaced moving parts. It also has an attached Micro USB cord, and a regular USB output in case you have another type of cable you need to attach. As versatile as anything on the market, testers loved the look, intuitive features and size of this Enerplex model.
