I want an electric kettle that can run off 120 and has a battery for quick boiling. Bonus points if it's a gooseneck for coffee. I've never found one though.
It is going to be expensive and heavy. 120V can do 1200W. To get that current, you need something like LiFePO4 12V 100Ah battery which can get for $200. Those are size of car battery and weigh 24lbs. Obviously that would go in the base not the kettle but will need to rearrange your kitchen. And that only halves the time, more batteries are needed for more power.
Many offices have taps with instant hot water dispensers. Or just refillable dispenser, popular in Japan - IIRC they don’t waste much energy due to insulation.
Love mine. Boils in less than two minutes, you can schedule the boil, the thermostat is accurate and the gooseneck is accurate as hell, but is only good for pour-overs.
