CES 2013 offered a cornucopia of smartphone accessories, but the most impressive device is PowerA’s Moga Pro. Building on the trend of smartphone gaming, the Moga Pro is a full-size Bluetooth-connected controller built specifically for Android games. Instead of forcing users to smudge up their screens, the Moga Pro draws on the tried-and-true design of console-style controllers--complete with rear bumpers and joysticks--to give users a more intuitive and responsive experience. An included miniHDMI port between the bumpers even lets users stream content to their TVs. An extendable arm located on the rear of the Pro can hold smartphones as large as the massive Galaxy Note II. So no matter what Android phone you have, you’ll be able to maximize its gaming fun.
