This is a WAVEBOX portable microwave oven. It's a 100V/12V compatible type. I acquired this used, but I'm selling it because I have no use for it. The main unit only, and there is no 12V cable. The 100V cable is the three-prong type commonly found on PC power supplies. I will include the one I was using. I'm adding this because I received a question about its operation. The items I put in it do heat up properly, so I believe it is functioning normally. However, this product is designed to be portable, so some aspects are simplified. There may be some unevenness in the heating.
