Instant Pot sold a model called the Max which went up to the full pressure of stovetop pressure cookers. It didn’t sell. The problem is that it took so much longer to reach the highest pressure. The main limitation? North American household 110V 15-amp circuits max out at 1650W (and typical appliances max out around 1350W to leave margin).
If we had European 240V circuits we could have an Instant Pot designed for well over 2000W and it wouldn’t be an issue.
The same story goes for electric kettles. Alec of Technology Connections [1] went into extensive detail about it!
