The Handpresso works by using your own personal manpower to create the necessary pressure by pumping the handle, after which the machine produces one shot of espresso. And according to our sister site Slashfood's product review, the espresso isn't half bad.
For me part of the fun of camping is drinking something different, like coffee made in a steel pan over the fire, and laughing about how bad it is. But then I can't remember the last time I actually went camping so maybe there's something to bringing a little bit of home out with you to the wilds. $155
