My two cents from a lifetime of coffee drinking and camping.
Instant coffee for a fix, just to survive. Always have some somewhere. Don't need the water real hot. I had a small jar even when backpacking.
Pour over is great, one cup at a time.
French press takes less room than a percolator but it's messy and only makes two cups. I have used mine a lot tent camping.
Percolators are good for more cups and you don't need a separate pot just to boil water in.
I have settled on
this drip maker by Coleman because it's just like home.
