Oukitel K10000 is the first Smartphone in the world with the largest battery at 10,000mAh. With such battery storage, users need not worry as to how many hours it take to fully charge it, because it is said to take only 3.5 hours from 0 to 100. The device also supports reverse charge functionality. This means that the device can serve as a power bank as well. Also, the K10000 may last up to 15 days with normal usage. The K10000’s sensational longevity gives it quite the unique selling point. The company claimed that the smartphone can charge three iPhone 6s or single iPhone 6s on three different times and still have 10 percent juice left. Oukitel K10000 features a 5.5-inch HD IPS display with 720 x 1280 pixel resolution. It comes with a 1GHz quad-core MediaTek MT6735 processor coupled with 2GB RAM. The inbuilt storage capacity is 16GB and can be expanded up to 32GB via microSD card. The device also features smart gestures and Xender for file transfer. Oukitel K10000 also features a new flagship with a dual-SIM functionality that runs Android 5.1 Lollipop operating system. The device camera comes with a 2MP front-facing and 8MP rear. On the connectivity front, it comes with 3G technology, Wi-Fi, Bluetooth, microUSB, and GPRS/ EDGE GPS/A-GPS. However, the insane 10,000 mAh battery accounts for the bulk of the phone’s weight, of course, making it into a rather lethal weapon. It is almost unbelievable that a smartphone with such an outstanding battery is coming soon, as smartphone usually consumes more battery. The mobile is priced at $ 239.99 and shipping of the device will start on 2 January, 2016. Those customers who wish to enjoy smartphone with high end battery can go ahead and pre-order, as it available globally with discounted offers in some stores.
