We’ve all been there. Midway through a grueling plane ride, with no in-flight entertainment to speak of, when suddenly your portable music player flashes that godforsaken low-battery warning you’ve been dreading since the moment you realized you left your charger back home.

So what do you do when the music finally cuts out and all you’re left with is three seconds of ear-ringing silence followed by the phlegm-choked gargled snoring of the 300-pound Texas soccer mom sitting to your left? Now there’s a way to escape your misery: ChargeCard, a tiny, portable battery charger that’s compatible with just about any electronic device you can throw at it. It weighs only two ounces, measures just a quarter-inch thick and carries twice the charge of most other portable battery chargers. So, take that, boredom. Check it out here.
