Okay, pop quiz! What do you reach for when your phone is on its last 2% and you still have a full afternoon of business emails, calls, and social media on your plate? You reach for your ChargeCard of course. No, no, not that one, this one:

ChargeCard® Ultra-Thin Credit Card Size Phone Charger

Getting the most out of your smartphone is hard if the battery can’t keep up with your daily grind, and lugging an oversized spare battery with you just isn’t going to cut it. The ChargeCard is an ultra-thin phone charger that stores 2300 mAh of juice, which is plenty to push a dying phone all the way to sunset and beyond.

Right now, the company behind ChargeCard, AquaVault, has a stellar deal that will get you two of the credit-card-sized chargers for just $60. That’s a buy-one-get-one-free sale that essentially cuts the price of these handy little gadgets in half.
