While you’re traveling is the worst time to run out of juice. So don’t leave your phone or laptop battery up to the airport charger gods.

Next time you’re packing your devices for a flight, stash a power cord in your carry-on. That way you’ll always have your own private power station. And the extra length means you’ll never get stuck hugging the wall with the other folks juicing their laptops and tablets and phones and personal massaging devices.
