How Do You Turn a Smartphone Into a Powerbank?

Reverse charging is found on more and more Android smartphones and rugged phones. It allows you to charge your smartwatch, wireless headphones or even your friend's phone using your own smartphone. Oukitel has also integrated this feature into most of its rugged models. 

Let's say you're using Oukitel WP15S. It comes with a massive 15 600mAh battery which can  ensure mileage like never before. When it's fully charged, it can last up to 1300hrs on standby, 130hrs of calling, 247hrs of playing music and up to 35hrs of playing games. You can easily use some of this capacity to charge your other small devices when travelling. 

So how does the reverse charging mode work?

On-The-Go (OTG) is a USB transmitting technology that allows a device to directly connect to an external device such as a wireless headsets, smart watch, etc. with the help of an OTG cable. You can find OTG cable in your Oukitel WP15S box and use it to charge other devices.
