For the uninformed, the Xbox One uses wireless controllers that requires AA batteries. This may be an inconvenience to some, especially when you considered that both the PlayStation 4 and Nintendo Wii U include controllers with rechargeable batteries built right in. With products like the Xbox One Dual Charging Dock, however, you should not have to worry about buying any new AA batteries.
