A backup battery is only as useful as the cables you remembered to bring to connect your phone or tablet. Bring the wrong one, and your device will die a slow, frustrating death. So that's why Digital Treasures has integrated USB, microUSB, Lightning, and Apple Dock Connector cables into its new ChargeIt 3600mAh backup battery.
The adapters are permanent too, so there's no chance of them ever going missing or getting borrowed and never returned. And between the four of them you should be able to top off almost any modern device. At $50 it's not only there to save your phone's dying battery, but it also helps save your bag from becoming a rat's nest of tangled charging cables. [Digital Treasures]
