Games on the iPhone are great, and they only seem to get better — but controlling a game by tilting, shaking, and occasionally poking at a glass screen leaves something to be desired. With the Moga Ace Power Controller ($100), you get all the controls you're used to with console gaming, without sacrificing the convenience and portability of your phone. The controller expands to cradle your phone, and collapse back down to a small size to fit in your pocket or bag. It features dual analog sticks, a directional button, four action buttons, as well as left and right bumpers and triggers. Best yet, the controller also doubles as an extra battery pack, letting you keep a charge while you play. Compatible with all fifth generation iPhones and iPod touches.
