This wireless charging station keeps my Xbox One controllers functional. I hate using disposables in the controllers and swapping batteries is no fun.
I really only play Destiny on the Xbox One at this point, but my controllers were often dead. I think the self power off timer in the units isn't very good as it seems the batteries go dead once every week or two. This base station comes with 2 rechargeable batteries that contact when you set them in its cradle. All my dead battery problems are solved.
