we are traveling on us air and the plane only has usb charger ports near the seats and all my stuff, laptops etc..have a regular three prong plug. what can i use to charge my stuff on the plane making use of the usb? I NEED an adapter to get an ac/dc plug into a usb plug. or even better if there something which plugs into a usb port that allows for more than one thing to be plugged into it?
thanks
