Coming in a variety of colors, Lepow's Moonstone 6000mAh Power Bank ($70) is a compact USB charging solution. The piano lacquer-finished block offers two outputs; one is 2.1A, suitable for both iPads and lower-end devices, while the other peaks at an unusual 1.2A for smaller devices. Lepow includes a free felt carrying case, as well a micro-USB recharging cable, but you must supply your own Dock Connector or Lightning cords.
