Cobra Power Deluxe ADVANCE

Teaches: a peripheral for the Game Boy Advance

CTR Review

This "Plug and Play" power pack uses rechargeable batteries to give you up to 16 hours of play. The only downside is that it adds a large bulge to the bottom of your Game Boy Advance, which interferes with games like Tony Hawk. We especially liked the status LED (light) that tells you the power level of the batteries. This is especially nice if you use a power draining light accessory as well.
