Turns out, it's not heat which is the enemy of good coffee, but too much heat.
The best coffee warmer is one that keeps your coffee at a controlled drinking temperature. The problem with a thermos is that it will keep the coffee too hot for comfortable drinking initially. Reheating will burn the coffee.
So anything which keeps the coffee at around 50°C will be good. Product recommendations are off-topic here, but James Hoffmann recommends a specific mug in above linked video, although that seems a bit pricey to me (I actually only found it for about 200€).
Heat is the enemy of coffee.
I brew my coffee in a French press and then transfer it into a carafe, the carafe keeps it from cooling down.
I only pour out 1/3 to 1/2 of a cup at a time.
No unnecessary use of electricity.
