Tea candles are wonderful for this. I keep my Chemex over a candle and pour myself smaller cups from it, but I’m sure you can find solutions where you put the coffee cup directly over the candle as well. A coffee cup with built-in heating elements and electronics sounds insanely overkill.
Or you could use a spirit lamp instead of a candle. Top up the lamp and your drink with alcohol!
Don’t actually do this unless you have some very high % drinking spirits, fuels usually have various toxic things added to them to prevent you from having fun.
