ReVIVE Series Solar ReStore External Battery Pack with Universal USB Charging Port
Accessory Powers ReVIVE Series Solar ReStore External Battery Pack is something that would be at home for researchers who are away from a civilization for days at a time, for whose whose idea of fun is camping in the middle of nowhere or in a disaster kit. The ReStore External Battery Pack is essentially a battery pack with a solar cell on one side, with USB power outputs and an LED light that stows away when not is use. To be fair, the 1,500mAh battery can only be charged up to 50 percent using the solar cell, but it is easily portable with a fair amount of practical use. It's compatible with all iPhone models.
