When I've been off the grid I usually resorted to Cowboy Coffee: Boil up some coffee in a pan with a couple of egg shells. That is really the "American classic". If available, I will use a tea strainer to filter the grounds out. Otherwise they settle to the bottom of your cup. Not a problem.
I’ve got a Mocha Pot but it takes a lot of heat. I got used to espresso when I worked for a company down in Hollywood, FL. of 100 people with 80 of them being Hispanic. They made it every mid morning.

That’s how my grandpa used to make it.
