Although the Robot Head Portable Charger is based on a cardboard character known as Danbo, this battery charger is not made of cardboard. It’s a sturdy external battery that packs 6000mAh behind its cute face. Press the mouth and the eyes light up to indicate battery charge levels. Its small enough to fit in your pocket at about 1.4″ X 1.9″ X 2.9″, and you’ll hardly notice its 5 ounces in your gear bag. It has two USB ports and can charge two devices simultaneously. One port is 5V at 1A; the other is 5V at 2.1A for charging tablets. The Robot Head Portable Charger is $58.29 at Firebox.
