I wish I had access to the state of charge stats or anything, cause ive always been curious how much of the battery it uses. all I can say is that it's a decently nice stove, the oven is great, but that I wish they had made at least one ofthe induction pads large enough to fully heat a 12 inch skillet. They're all the same size, I think 8 inch? So big pans are hotter in the middle, and the outer 2-3 inches are noticeable cooler and never boil. For that reason I don't recommend it, given that its like 6 grand or something, gimme a full size induction coil
