USB devices charge via airline audio jack

Energizer recently announced their Energi To Go line, but here is a solution that you can use on your next transcontinental flight. The InFlight Power USB unit plugs into a standard 3.5mm headphone jack, uses a trickle charger for 3-5 minutes to store up some juice, and then fires it out the USB port for about a minute. The cycle renews, more power is had, and smiles can be found all around.

In this way, any USB-powered device can get a fairly decent boost of power while you’re on the plane (assuming you’re not stuck on one of those aircrafts with propriety headphone jacks, in which case you have to buy their adapter). Of course, for best results, you’ll want to crank up the volume.

For cell phones, PDAs, iPods, and any number of other portable electronic devices that can’t take power directly from a USB port, the good people at InflightPower.com have you covered as well, because they have a supply of adapter tips for over 700 devices.

The basic InFlight Power USB Unit is 35 bucks, but for the full meal deal, you’ll want to drop $50 plus five for each additional tip.
