When one generally thinks about smartphones that come with extremely big batteries, we assume something along the lines of a 5,000 to 6,000 mAh cell is pictured. Those, however, have just been dwarfed by the Oukitel K10000. This handset out of China is now the king of battery capacity, as it's claimed to sport the largest cell ever put into a phone. As its name implies, the K10000 has a whopping 10,000 mAh battery. And it's now up for global pre-order for those who are interested. The normal price is $239.99, but apparently you can use the promo code K10000 to get that down to just $199.99. Gearbest will start shipping the device on January 2. Oukitel brags that the K10000 can fully charge three iPhone 6s Plus units (or just one, but three different times) and still have 10% battery life left.

When you look past the battery, though, the Oukitel K10000 is nothing but a mid-range smartphone. It does however feature the nowadays trendy metal frame, and it has a rather unusual design. The K10000 comes with a 5.5-inch 720p IPS touchscreen, an 8 MP rear camera with LED flash, a 2 MP selfie shooter, the MediaTek MT6735 SoC with 1 GHz quad-core Cortex-A53 CPU, 2GB of RAM, 16GB of expandable storage, 4G LTE, and dual-SIM functionality. Its dimensions are 143 x 77 x 9 mm, and it weighs 184g. It runs Android 5.1...
