The Zap&Go charger gets topped up in just 5 minutes! It contains a 1,500 mAh supercapacitor, itself mostly made up of graphene instead of the more typical aluminum. This, coupled with a special power supply that funnels power in much faster, means that you could top-up the Zap&Go, then use that to recharge your mobile device at a more leisurely rate later on (since it won’t charge as fast, no matter what).
Currently a prototype only, it is undergoing a crowdfunding campaign with hopes of delivery in October 2015. A $99 pledge will secure you one.
