I don't need a MW, but the usual 600W to 900W in domestic ovens is
pitiful. What's wrong with 2kW?

Microwave heating instructions usually say what power they're for. Most
I've seen recently say 1 or 1.1KW. Maybe that's the normal for the new
units.

BTW, I have a 700W microwave about 30 years old.

The heating instructions are based on what is commercially available. If there were 2kW units around, they'd have those listed too, with shorter cooking times.
