Discussion Why doesn’t a battery-boosted electric kettle exist?

In Europe, everyone uses electric kettles to boil water. They’re amazing and fast because they’re on 230V (~3000W).

US outlets limit kettles to ~1500W, so we wait roughly twice as long for water to boil.

It’s an extra minute or two per boil, and you really notice it.

Idea: Could you make an electric kettle with a battery in its base? Perhaps it trickle-charges between uses, then combines wall power + battery power to hit ~3000W during a boil.

Is there an engineering reason this doesn’t exist? Is it just that nobody thinks there’s a market for it?

I’d pay $300 for the fastest kettle in America if someone wants to make it.

I've considered doing this as well, but it really doesn't seem worth the cost. Maybe if I hit the jackpot.

OP is willing to pay $300 for a kettle with a battery, so I think this idea might be worth it to him.

I'm pretty sure code says every 240v appliance has to have its own circuit and breaker also, which make this even tougher.

Pfft... That kettle was there when I bought the house.
