Mini Power Rechargeable Cardboard Batteries

Slowly but surely, batteries are getting better for our ever-expanding assortment of power-hungry devices; but they’re still not good enough. As we wait for a true breakthrough, inventions like Mini Power from designer Tsung Chih-Hsien become extremely appealing.

Though unfortunately it’s still in the concept stage, this 2014 Red Dot Design award winner is based on paper battery technology; just insert it into your device and go. You’d be able to find these little guys at convenience stores and such in two-, four- or six-hour varieties, and when drained, the option is there to bring them back to the store for recycling or recharging. Also, grab us a Slim Jim while you’re there. Think of them like 5-Hour Energy capsules for your smartphone, only without the caffeine side effects.
