Good: The i.Sound Portable Power Max battery can charge up to five USB items at once and has an onboard LED battery meter and LED flashlight. It's tiny enough to travel almost anywhere, and the included USB-to-Micro-/Mini-USB cable comes in very handy.
Bad: It's possible the device will lose its ability to hold a charge over time, but we didn't experience that in our testing. The USB ports are very close together, so items with a larger USB dongle frame may cover up other ports.
