Lived months straight on thru hikes in the woods using tiny denatured alcohol stove, you will not find easier/lighter solution but note best for single person (and smaller amounts of boiling water). I could go approx 3 weeks 2x daily boils before needing refill. Whisper light is best stove for fastest boil/high elevation/multi people and are pretty light and can regulate--my go to stove these days. the WL can burn multi fuel, including gasoline if necessary.
