We've been using a Breville Control Freak, a plug-in induction stovetop, for a couple years, and it's amazing: https://www.breville.com/us/en/products/commercial/cmc850.ht.... Controlling the heat via single degrees is great. It brings the pan and food to temperature far faster than any gas stove I've ever used. It is expensive but not breathing in gas fumes is also nice.
A company called Impulse (https://www.impulselabs.com/) says it's building stoves with lithium-iron phosphate (LFP) batteries built into them, such that they can run on a standard US 120v ~15a circuit.
