Hmmm.........

What is this thing exactly?

it's a portable Teppan Yaki grill, like they have in Japanese
restaurants where the chef cooks the food in front of you and generally
ponces about with it.

My feeling would be that the 3200W is the maximum it could possibly
draw flat out. In practice, this isn't going to happen.

indeed.

I suspect that if you cut off the plug and fitted a good quality 13A
plug with 13A fuse, and used it only on lightly loaded circuits, you
wouldn't have any problems.

it is tempting...!

Dan.
