Known for its typically stationary power accessories, APC's new Mobile Power Pack UPB10 ($70) is a 10 Watt-hour battery designed to recharge popular, but battery-draining, mobile devices like iPhones and iPods. The battery can be charged within 3 to 3.5 hours and then is ready to transfer its charge to the battery of your choice; it can fully power an iPhone for twice its standard run time and an iPod three times. Since it works by recharging a device's own battery instead of providing an alternate source of power, it can easily be removed when the process is complete.

..as a well-made, aesthetically neutral, and iPhone-ready solution—especially when found at a street price of $55-$60—it’s a solid power option, and deserving of our general recommendation.
