wow thats a awesome battery, then why can a normal laptop run off those batterys aint basicly the same thing as a xbox but dosnt game whats the diffrence?
a laptop uses about 20w. and they have power saving systems. they scale back the processor power when its not being taxed to save even more power. etc. My friend has a "laptop" thats about the same as a 360, and it has a 8aH battery in it, and it goes flat in about 25 minutes because it uses so much power. laptops only last any period of time on battery because they are tuned to be power-efficient. the 360 really isnt.
