Dead smartphone and dying to upload that holiday party pic to Facebook? Now Genius has released two ultra-thin power banks for the North American market. Both the ECO-u306 and ECO-u821 can charge two mobile devices at the same time. If just charging one device, the built-in concealable micro USB cable deploys for a quick charge when needed, while a Micro USB output connector allows for a second device to be charged.

Ultra-Thin Size
At 10mm, the ECO-u306 can be placed into user's pocket or easily stowed away. The ECO-u821 with more than double the capacity of the ECO-u306 is only 14.4 mm thin.

Battery Capacity
ECO-u306 uses a lithium-ion battery with a capacity of 3000mAh. This allows full recharging of most smartphones with capacity to spare. For more demanding phones, the ECO-u821 adds the ability to charge even the biggest phone multiple times or a tablet PC by holding a full 8000mAh.

Colors
The ECO-u821 comes in black or white, while the ECO-u306 comes in an assortment of colors, including black, white, blue, and pink.

Price and Availability

The ECO-u306 and ECO-u821 are currently available in the US and Canada for the suggested retail price of $27.99 and $44.99.
