    Hello, I don't know much about electronic devices, so please don't laugh at my question :-) Is there a battery operated kettle or cup to boil water? And if not, could something like this be created? Because I personally have never seen it anywhere. I am constantly traveling (on trains) and lugging full thermos bottles on my back is very taxing. Such a wonderful kettle or mug that would somehow boil water on its own, without a socket or electricity, e.g. with a battery or something similar, would make life much easier.

    Rest in Peace
    This can be done without any problems. Only instead of thermos flasks you will carry a full backpack of batteries or accumulators.

    Please read carefully, gentlemen. And use the feminine form when addressing a violet. :-) :-)

    The only thing not to lug around the battery and heaters is to smile at the conductor :D
    The rest as above :cry:

    1 watt second (1V x 1A for 1 second) heats 1 gram of water by 0.24°C.
    Heating 200g of water from 10 to 100°C requires 90x200 calories, or 75,420 watt-seconds, or 20.5 watt-hours.
    Such energy is stored in a 12V battery with a capacity of 2Ah, the battery weighs almost 1 kg and is enough for disposable boiling a glass of water. The battery costs about PLN 60 http://www.emma.net.pl/akumulator-bezobslugow...t=3010#nclid=d80d81d5c34ccd3cb83d726b9d67f3a4 .
    It is more advantageous to use a small "pitrasnik" with a spirit burner. There is energy in 1 liter of spirit several hundred times greater than that of a 1 kg battery.

    Gentlemen, thank you very much for your answers. I didn't think that boiling water would require carrying such heavy things with you. Oh well...

    Do you know if there are mugs with heaters and a normal wall plug? Because I've seen one, but with a plug into the socket in the car.

Topic summary

The discussion revolves around the feasibility of battery-operated kettles or cups for boiling water, particularly for travelers. Users highlight the impracticality of carrying heavy batteries required to power such devices, with estimates suggesting a large battery (around 20 kg) would be necessary to boil water efficiently. Alternatives like spirit burners are suggested as more practical solutions. The conversation also touches on the existence of heated mugs that can be plugged into wall sockets or car outlets, with links provided to products that claim to heat water quickly. Overall, while the concept of a portable battery-operated kettle is appealing, the technical challenges and weight considerations make it less viable.
