A smartphone with a battery of 10000 mAh? Oukitel will release one

  Chinese brand Oukitel is preparing a smartphone with a gigantic 10,000 mAh battery. It is still a prototype, but in theory, it would allow the device to last about a week before plugging it to a charger.
  Oukitel K10000 embarks a battery of 10,000 mAh, no less. Such capacity in an external battery will typically provide 5 full reloads. Thus, we can assume that the Oukitel smartphone would last about a week on a single charge.
