[quote name='Mega64']Mine had that same end. You plug one end to your Wii AC input, and the other to the AC adapter. Kind of weird how they did it, but it's working for me. (edit: beaten)
Another weird choice is how the unit's lights flash when charging and solid when charged. At least, that's what the instructions say. It may just be me, though.[/QUOTE]
I didnt even see that in the directions. They started flashing when I first set it up and just stopped flashing and are solid now after about 2 1/2 hours. The manual says 4-5 hours for full charge. Oh well, hopefully they carry a long charge and last a while.
I hate how they were thrown in a box and shipped like that.
