One of my favorite accessories around here, the power banks. Xiaomi give each of us their own Mi Power Bank which retails for about $11.50 USD right now on mi.com. This is a 10,400mAH battery pack with one USB port. We'll be testing it out over the coming days, but in the meantime we thought we'd do some hands on with it. It's a nicely built battery pack, made of aluminum, and is actually gold. Not too fond of the color, but the battery pack seems to work quite well so far.
