Yes, that's what we've been talking about. 120V 15A is not enough to run two burners at any kind of reasonable heat output, much less four. That's 900W->3000BTU/h per burner, assuming the electronics work optimally. Even accounting for the fact that induction is 100% more efficient than gas, you're talking about the equivalent of two 6000BTU/h gas burners, effectively. For reference, that's less power than the simmer burner on my gas range. The main burners of a cheap gas range are 15000BTU/h, and more expensive ranges go up to 25000BTU/h.

All this is of course fixed by installing a dedicated circuit for a real induction range. 220V * 40A increases the potential output six-fold, which is enough for any reasonable use case. But doing that is much more expensive, which is the whole of what I was trying to convey.

Gas stoves transfer very little of that heat to your food, most of it goes around your pans and into your kitchen. And the thing with high heat is that it gets drastically less efficient. Large flames push way more heat around the pot than they push into it.

We're not not talking about 100% differences, we're talking closer to 400%. At least that's what I've found when measuring boil times for a 1200w plug in unit compared to a 15000btu gas burner.

Of course 240v is an absolute must for a 4 burner range, but that's not uncommon nor hard to get. Almost every home in the US has at least one 240v connection in the house, and it's usually $200-300 to get one installed. That's not nothing, but it's way less than it costs to install a gas line.

The number I cited came from some random website that I Google searched. If you have a more authoritative number, I'm happy to see a citation, but I won't be convinced by you just saying so. FWIW, the low power claims I made r.e. 2 burner plug in induction cooktops match my personal experience using them.

I would be impressed if you could get 240 run from your breaker to your kitchen for $200, unless the breaker box is right next to your kitchen. The cost of the job is mostly going to depend on how time consuming it is to run the wires, assuming the wires already present are not sufficient for carrying 240v 40A. A brief search on the internet indicates a very wide range of quotes, probably dependent on site conditions and the local electrician labor market.
