So i bought myself a 360 for myself for xmas, and now im in a pickle. Tommorow im going shopping to burn up my money, i am buying gears of war

and an extra controller. Now my question is what is better: the Quick Charge or the Play and Charge. I know that i would need 2 play and charges to charge both while playing but only need on quick charge and could charge them while sleeping correct?
also a quick question about the quick charge. does it have unlimited recharges in it or will i need to buy another one? or does it have an ac adapter?
