The Apollo Max is a new 10000mAh power bank that, according to its maker ELECJET, integrates the emerging graphene standard as a battery material. This, it is claimed, gives it an "unbeatable charging efficiency of 96%". This new product is currently available as a reward on its Indiegogo campaign page.

At this speed, we don't need power bank anymore. Just put that battery in to an andoid phone and carry a charger instead.
Sounds overpriced. Power banks at $50 are already really good, by the end of that 1000 cycles something better will have been developed, for starters that energy density doesn't look anything special.
