The initial small ‘i’ clearly points out the fact that the device in question is related to iPhone. Brando’s iPower is a backup battery for those users who would like to make complete use of the big screen of Apple’s prodigal son. This backup battery has a unique feature, apart from its bulk. iPower comes with a built-in 1.5Wspeaker and thus delivers extra juice and also pumps up the volume. The docking feature would be especially appreciated while playing a movie. Its 2400mAh guarantees 3 hours of extra life. iPower comes for both the generations of iPhone and the 3G version boasts of external volume control buttons. Brando’s offering will cost you a mere 44 greenbacks.
