Percolator for fresh coffee??? Nooooo a percolator boils the coffee.

Try a Melitta Manual Coffee Maker. Use any good kettle to bring the water up to 200°F (195-205°F) and just pour the water slowly over the coffee grounds sitting in the cone filter. It makes a very good cup of coffee; I use one daily with freshly ground beans.

A 5-inch stainless-steel stem thermometer is handy to get the water in that small range 'tween hot enough to get flavor out of the grounds and not so hot that the coffee turns acidic (195-205°F).

Given a loss of electricity, I'd bring the water up to the correct temp using one of my camp/hiking stoves (yes the Coleman two burner propane is a good choice) and otherwise make the same great cup of coffee I make daily with an electric stove-top.
