Say you're in Dolores Park, trying to look at Facebook and stuff and your battery is running super low from trying unsuccessfully to send the same text over and over because, lol!, there's no service!  You could run home and charge it up; or you could hit up Lynn on AirBnB, who's now offering up her sweet apartment as a quasi-airport charging station:

So you're hanging out in the Mish all day. Instagramming like crazy, taking pics of all the things, and now you have to go to dinner in 2 hours, and your phone has 20% battery left… HOW will you survive???

Drop off your phone at my place, we'll let it charge for an hour or two. $5/hr - it's not so much to pay - after all, you're going to be in the hood for 6 more hours. Those incriminating photos don't take themselves! Charge your phone!

Charge your phone!
