OnePlus is marking its one-year anniversary by launching the OnePlus Power Bank, a 10,000 mAh external battery pack that is designed to go with the OnePlus One. The external battery pack can charge the OnePlus One three times over, and the presence of dual-USB connectors allows you to charge two devices simultaneously.
The OnePlus Power Bank is available in the same color variations as the OnePlus One: Silk White and Sandstone Black. The battery pack does not feature any buttons, with the vendor stating that a shake is all that's required to activate the LEDs that tell you the charge status. The external battery pack costs $15, will be available early next year from the vendor's official website.
OnePlus has also revealed that it is looking for ideas on a name for its upcoming custom ROM, which will be "stock, bloat-free, and highly customizable." If you've got any suggestions, be sure to enter them here.
