The Teppenyaki is 1800watts, but it has 5 settings to reduce the heat, and we have never had a problem using it in France. I also have never had a problem with the Teflon coating and sticking as Sprocket has, possibly he bought a very early one, and they have improved the finish.
However ALDI also now offer a Teppenyaki Tray, with no power connection, but with a pan like circular section on the bottom, price about £10-00. I now use this in conjunction with an Electric Induction hob from LIDL, also offered by ALDI, price about £30-00. This has a 2000watt element but with a control that can take it down in 200watt movements and I find that 1200watt is good to start the cooking , but drop it to 800watt when I need to slow the cooking down. I find this gives far better control of the heat than the electric teppenyaki grill. It also means the heat is more central, allowing the outside edges to have sufficient heat to keep food warm. whilst cooking other items.
I should add that you need cooking pans that are magnetic when using an Induction Hob, so aluminium pots and pans will not work on it.
As with all items in ALDI & LIDL they are not always available and it can be many months before an item is offered again, so patience is needed.
