Forget picking up a gigantic USB battery, or shoving your phone into an equally bulky battery case -- if Oukitel has its way, your phone will have the juice you need for days on end. Its upcoming K10000 smartphone has a whopping 10,000mAh battery that, under "normal" use, reportedly lasts for 10 to 15 days per charge. If this isn't just marketing fluff, you could go on a week-long vacation and still have enough energy to upload your photos before plugging in. And like some high-capacity phones, you can use any excess electricity to top up other devices.
If you read this and thought "there has to be a catch..." well, your suspicions are well-founded. The K10000's performance is quite modest, to put it mildly. You're looking at a quad-core 1GHz MediaTek processor, 720p (if 5.5-inch) screen, 8-megapixel rear camera, 2-megapixel front cam and 16GB of expandable storage. Also, don't be surprised if the 3G and LTE don't work in your corner of the globe. Think of this more as an enormous battery with a phone attached than anything else. Even so, that $240 pre-order price (it ships on January 21st) might be hard to resist if you're looking for a smartphone that will keep running through that next camping trip.
