OnePlus Bank Tag

Excellent solution, cheaply, by OnePlus here is its Power Bank

OnePlus recently announced OnePlus Bank, an accessory that can be used both for both tablet and smartphone that is born, basically, to celebrate the first year of operation; mind you we speak of a single year, and is something that certainly does honor to the company, given that in such a short time has managed to get some good results with OnePlus One (and some other accessory).
