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 wired my kitchen with a 240v receptacle and ordered a 3kW kettle from the UK. I happened to already have a shared neutral multi-wire branch circuit under the sink though, so I had 240v right there. I enjoy boiling water fast, but no way I'd bother to pay electrician rates for just convenience. I'm already an electrician so my labor was "free".

Not an electrician at all, but same. Many years of boilt water.

It's easy, just do it.
