Your iPhone might need a little help staying awake, and external battery sources might provide the necessary kick up the arse.
According to multiple reports, the new Apple iOS 7.1 currently running iPhones around the globe sucks the devices'' batteries faster than ever before, often providing wildly dropping power levels before sending the smartphones to a data saving sleep function.
If you're running 7.1, you can certainly keep an iPhone plugged via a wall charger or car unit, but — once in use and on the run — you're still likely to need a secondary external power source.
Below you'll find a quick visual listing of some favorite charging options, including a case, battery packs and even an ole' fashioned hand crank unit.
We'll help keep you on the line one way or another, so power up out there.
