There’s a new product out that lets you draw power for any USB-chargeable device from the headphone jack on your armrest while in an airplane. Sounds pretty cool huh? It’s called Inflight Power and the adapter for the headphone jack.

You plug the cord into your seat’s audio jack, turn the dial to a channel with consistently loud music such as rock music, put the volume all the way up and plug in your device. It doesn’t look like they will work for laptops unfortunately.
