Do not buy! Warning this adaptor is a very cheap replica of the real Wii adaptor, it is half the weight of the real one, it's not UL certified, and produces a fuzzy picture. I purchased this product, to have a spare one and I noticed the differences as soon as I took it out of the package and used it. A fuzzy bar keeps repeating on the screen moving up, which affects gameplay and probably is under powering your Wii, which could be damaging!
DO not buy this cheap power adaptor!! Buy the Nyko Power Adaptor instead if you really need one, it costs more, but it is worth it!

When using this adapter the picture was fuzzy and distorted which did not happen when using the original. I went and bought the original and returned this one.It cost more, but much better picture. Asked to have returned shipping credited due to defective/poor product......never got it!
