DigiPower has laid claim to the world’s slimmest and lightest titles with their latest auxiliary battery pack that will target smartphone owners. Heck, it is small enough to resemble an iPod touch or a regular iPod, sans the display, of course. The battery pack itself measures 0.25″ thin, tipping the scales at just two ounces. Packing in 1100mAh of power, DigiPower’s battery pack will set you back by $29.95. Touted to offer over three hours of 3G talk time, seven more video playback hours and 21 more hours of audio, this battery pack is equipped with a trio of LEDs that shows off the charge status, not to mention the essential On/Off button as well. Various USB connectivity tips have been included to make it play nice with various devices without a hitch. You might want to consider getting one since it is pretty hard to figure out just when you might need emergency juice.
