ElecJet Apollo Ultra: Powerful fast charger

ElecJet makes a bold claim about its Apollo Ultra power bank: apparently it is the fastest in the world. Currently in a crowdfunding campaign on Indiegogo, the 10,000mAh power bank has a claimed charging time of 27 minutes and a stated capacity of three times larger than your phone. You'd be forgiven for thinking that the power bank was going to be about the size of a brick, but it's still reasonably compact. ElecJet uses graphene to not only boost the speed of the Apollo Ultra compared to its rivals, but also to make it last longer, with 2,500 cycles, outstripping the traditional lithium battery and making it a little more eco-friendly.
