Quarter Powerbank

Using a backup battery to recharge your phone is straightforward, but what about recharging the pack itself? Quarter Powerbank cuts one more cable out of the equation, charging its 5,000 mAh reserves using your MacBook’s MagSafe 2 power adapter in a speedy 15 minutes (though in a pinch it’ll charge using Micro USB, albeit slower). It’s just 12.5 mm thin so it’ll slip away into a pack or even a pocket near unnoticed, and features no buttons of any kind: instead, shake it to power up and start charging your device.
