Genius ECO-u821 8000mAh Power Bank Review

There are quite a few different portable power solutions on the market today, and some of them are super bulky and others are very slim - but don't offer a lot of additional power. The Genius ECO-u821 tries to be the perfect middle ground with a nice slim size, not too large of a footprint and enough power to charge your devices a few times.
