This is the sort of current that brings mighty power supplies crashing to their knees. Up the creek without a plug-in. But when you are finished you still have the issue of delivery. You didn't bring a printer of course, and you don't know anyone in that particular national forest whose printer you can commandeer. This is nowhere near as easy as it sounds.
Pay phones are unpluggable.
People out on the perimeter often still have the old nonmodular plugs. The woman in the post office just whistles. The man in the diner doesn't know what a modem is. The library wants to see your card. Motels want you to check in before making a call.
