Here's a cool little smartphone battery pack from the gadget makers at Cheero. The charger takes the shape of Danboard, an iconic manga character made of cardboard, but don't be fooled by the cuteness--this thing packs a lot of juice. How much juice, you ask? 6000mAh, we answer. What the hell is mAh, you ask? It's a measure of battery capacity, and in this case it means you can charge your iPhone from empty to full 2.5 times, before the Cheero itself needs a charge. Two jacks mean you can charge up at the same time as a loved one or an annoying office co-worker. Get it via Opening Ceremony.
