Anker PowerCore II, $33 with code ANK20AH3

Anker’s PowerCore line has reigned as our readers’ favorite USB battery pack for over a year, and its long awaited sequel is down to $33 today, the best price we’ve seen.

In addition to a fresh new design, the PowerCore Elite (previously called the PowerCore II) includes three high speed USB charging ports with a whopping 30W shared between them, plus dual 10W microUSB inputs, allowing you to recharge the entire brick in as little as six hours, which is extremely impressive for a battery of this size.
