iPhones are power hungry little devices. They'll go through a charge in no time if you are using them on the go. Brando's come up with their new version of their extra-power supply for the iPhone. This device sets itself apart by including a built-in speaker.
The device itself is quite large since it houses a 2400mAh battery inside, giving your iPhone an extra three hours of battery life. It also includes a grip arm to securely hold the phone, a power switch and volume control. It's available through Brando's website for $44.
