I have a similar concern with charging my phone using USB ports in public places. Got a reminder last week while returning from an international trip. The plane had both power outlet and USB port for charging (Really glad they had them there). To charge my phone, first I connected to USB port (since I had the cable handy)and surprisingly got a message about authorizing the computer etc. I had the power adapter as well so pulled it out and charged using it instead.

We need a way to give us assurance that port is in just power mode.
