On paper, the idea of a Pikachu USB plug that fits into the wall with his ears is a good one, but not when you decide to put the USB port directly across from his ears. No matter which side you look at, there is something not right about this USB plug...
As Nerd Approved points out, that's not the only problem with the plug, there's also the whole being terrible for children thing as it encourages them to put random things in outlets and has very easy-to-swallow ear covers. Sure it may be designed for adults, but there's no denying that the design will appeal to kids who hopefully won't play with it in the wrong way.
