i.Sound Portable Power

The 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.

The 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.

The Bottom Line Lightweight, quick, and easy to use, the i.Sound Portable Power Max battery is a great way to keep your USB gadgets going when a wall charger isn't accessible.

i.Sound Portable Power

As the owner of an HTC Evo 4G, I'm quite familiar with the need to recharge my mobile device at least twice a day. But when I'm not commuting to and from CNET's New York offices, locating an accessible outlet can sometimes be a problem.

I tried using third-party extended batteries that made my phone bulkier than it already is, but on top of the additional size I found that after a few months they could never hold the maximum charge they were once capable of.

It seemed like a fitting coincidence that I recently was sent two i.Sound Portable Power Max batteries for review. The mobile chargers come in two sizes, 8,000 mAh and 16,000 mAh, retailing at $90 and $120 respectively.
