Anyone looking for a solid Android gaming controller need look no further than the MOGA series. The original controller launched a year ago, and while there were and remain some drawbacks to the bundled software, the hardware itself is top notch. The latest generation hopes to address a fundamental drawback to gaming on a smartphone, the inescapable battery draining forces at work whenever you fire up a graphically intensive game and attempt to play it using a Bluetooth controller.
Update: It looks like we might not be able to plug our phones into our controllers just yet. The Amazon link has already changed to say that the MOGA Hero Power is temporarily out of stock. Keep an eye out, as it will probably reappear before or around the launch of the MOGA Pro Power.
Android games are consistently getting better, but there's a drawback. As new titles task players with taking control of more detailed character models, paint surfaces with higher resolution textures, and follow up attacks with an increasing number of particles, phones with passable battery life soon find that they can hardly make it through morning.
