Well, not everyone can be trusted. 3 years ago, I "lost" a unique battery charger and spare battery (it would fit only one type of smartphone) at the shower trailer at Vintage. I've since changed smartphones, so it's no longer an issue. But being "carefuller" now, I don't leave my electronics anywhere.

Incidentally, in the winter time I plug a maintainer into my battery, directly--keeps it at top charge and warm. So I made up a lighter socket to plug into that receptacle, so that over the week I was at OSH this year, I kept my electronics charged from the airplane's battery without having to turn on the master. I regularly recharged my iPad Mini and my smart phone every day. None of the electronics takes much power to recharge. By the time I cranked up on Sunday, the airplane's battery still showed 12.1 volts so the engine easily started.
