Power Plug Size on DS

Does anyone know what size or “letter” of the size of the plug used on the DS?

I am looking to make my own power cable and I want to pick up a plug for it but am not sure what exact size to get.

I believe it’s an “M”

I believe it is RadioShack size “M”. I just took my DS into RadioShack and tested them before I bought them.

Thanks for the quick reply.
