For all of you who just got the Basic Wii u Bundle, here is the charging cradle which you can place your gamepad in when you finish playing so its charged up for next use and doesn't get damaged lying on the floor.
Wii U Gamepad Cradle and Stand $9 @ EB Games
Does not come with AC adaptor, you use the adaptor you received with Basic bundle.
Also $9 in store if you can find stock. I got one ahead of my purchase of the Wii U last week and Woden, Canberra I believe had two or so left. Their stock wasn't on the shelf, it was all out back so it may be worth asking staff.
