Ac/dc plug to usb...exist?
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
thanks

I hope not as the current draw would at the very least blow fuses if not shut down parts of the plane - which comes under the category of "VERY BAD IDEA".
Use the USB port to charge phones, ipods and some cameras. DON'T try to use it on anything else

Even with superconducting wire/transformers, perfect power factors, etc., you could pull about 8 mA, which is about 1/200th of what I need to run my laptop.

The laptop is out of the question - way too much current draw. If you have other devices (phone, MP3/Ipod, GPS) that have an AC wall plug on one end but terminate in a mini or micro USB, you can just get a standard cable to charge. You might be able to plug in two through a non-powerd USB hub, but current draw is still going to be limited and they may charge VERY slowly, or not at all.
