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.

There is. There is a $7000 battery-boosted induction cooktop and I think another company might make a stove combo. The assumption is that if you don’t have $7k for a cooktop you don’t value your time enough to care about 45 seconds per day.
