The G1’s battery life isn’t as great as we would like, which is an issue with smartphones in general. That’s why this $17 device is a great idea. It will come in very handy for keeping your Android G1 powered at all times. It will charge your G1, plus there’s an extra dock to power a second battery, making it perfect for travelers who carry a spare battery. It’s a cheap way to make sure you always have some precious juice.

The Ant Commandos Double Range Guitar sells for $59.99 and does double duty, since it can play both Guitar Hero and Rock Band in one guitar. The Double Range Guitar plays PS2 and PS3 versions of both Guitar Hero (I, II and III) and Rock Band.

It operates on 2.4GHz wireless technology with a belt clip that gives players unlimited freedom. All of the functionality is retained, like a second set of Rock Band solo buttons near the strum bar and distortion effects. This is a great option for those with limited space who want to play both games.
