The only significant variable is time and when it comes to me getting my coffee in the AM, I'm not that patient.
Exactly, with an electric water heater it would take literally seconds to boil water even in windy areas where the propane stove takes FOREVER.

Like I said in my practice, to boil 1L of water, a 1500W water heater takes about 2 minutes (so 120 seconds, lol) equated to 12V power this requires 125 Amps. Where as an average 2 burner propane stove take about 3.5 minutes to boil about 1L.

125 Amp drain for 2 minutes to save a minute and a half (even for coffee) is not worth the toll on my batteries for me. Going with a lesser wattage heater should still end up having close to the same over all battery drain but just at a slower rate, so it will take longer to heat the water. Probably at that point, longer than the stove. So I'm still a stove fan. LOL

We are on a completely different page here. When camping in the middle of some desert during winter, or at a considerable elevation, cold wind blowing, maybe almost freezing temperatures, it may take 30-45 minutes to boil water with a small stove. Even a regular full-sized one can have a hard time heating up the cold pot while wind is blowing. 15-20 minutes is not uncommon.

On the other hand, if the weather is nice and no wind, there is no need to rush and have hot water ready right away.

I see the electric boiling more like a way to ensure the morning starts OK even in the worst case situation.

Anyway, I got a use case where the inverter is a good idea indeed: inverter very close to the battery and then a 110V line that runs inside the tent so an hot beverage can be prepared there without even getting out of the sleeping bag. Just remember to put the water in the 110V water boiler the night before, in case it freezes overnight.

We must do very different kind of camping!
