Finding outlets to charge along the trail

[krshome]

How does one go about finding a place along the trail for charging your power cell and phone? Are the only places just when you head into town or are there places along the trail that are regularly passed? Are businesses pretty cool about letting you use their power? Lastly what do you do for the 6 hours it takes to charge a power cell? I need power through out the hike but it seem like a real pain.

Edit: I do realize the shelters and trees don't have outlets to charge nor is there poles with outlets along the trail just for hikers. Im interested in how often there are places like ranger stations, maintenance buildings or shops at trail crossings that i might be able to use without going into town. I don't have a screen addiction I'm just running a business I'm gone, so need to stay in contact.
