At 7mm thickness, Edge is the slimmest 5000 mAh Power Bank in the world. So slim and lightweight, it can be carried right into your pocket or purse with complete ease - which is why we say, slimmer is indeed better! Its 5000 mAh lithium-ion polymer battery provides enough power juice to charge up a smartphone up to 2-3 times. A complete power solution, the Edge Power Bank requires no excess cables to be carried with it, thanks to its built-in Micro USB charging cable. Apple or Android, Edge has all major OS platform devices covered, carrying an 8-pin adapter in its integrated slot. Dual, simultaneous charging becomes possible with the Power Bank's additional USB output port. Meanwhile Edge's LED indication bulb communicates the Power Bank's remaining battery status at a glance. All in all, this revolutionary power source is truly a class part. An 8-Pin Lightning adapter to charge iOS devices comes with the Power Bank.
