WaveBox Portable Microwave

The microwave is in pretty much every kitchen, it is an amazing kitchen gadget that has changed the way humans cook.  When I first saw the WaveBox Portable microwave I thought it ran on batteries and was truly portable.  Turns out it needs to be plugged in to the car or wall socket.  So is this just a microwave with a handle?  You can buy it here for around $229.
