Some people can't live without caffeine, so to those addicts, I'd say check out the Coleman Portable Propane Coffeemaker.
With the Coleman Portable Propane Coffeemaker, you'll be able to have coffee wherever you go. Camping out in the wilderness and you need your caffeine? No problem, this little device will give you your fix with no complications. It operates on a single standard 16.4 oz propane cylinder, which means no cords, stove, or percolator is needed. It'll pump out about ten cups worth of coffee and runs up to 4.4 hours on one 16.4 oz propane cylinder.
The Coleman Portable Propane Coffeemaker is worth the investment if you're looking for a portable machine to bring with you wherever you go. It's perfect for camping and would make the wilderness more bearable for the avid caffeine drinker.
