Charge other devices with your Android phone

Lets say your friend's Android phone is out of charge. Did you know it's possible to lend some battery voltage to other Android phones? Yes, it can be done. Read on!

First of all, get a USB OTG -cable. They can be found everywhere. Here is one: https://www.verkkokauppa.com/fi/catalog/7744d/USB-OTG for 6,90 € (in Helsinki, Finland).

Next, find out if your Android phone supports OTG (On The Go). Download and install USB OTG Checker from Play Store. Check your phone to see if USB OTG support exists.

After the above steps it's time to connect your phone with another phone. Use the USB OTG -cable and your normal USB charging cable. Thumbs up your friend's phone will be charged! And hey, not only phone-phone can be connected but phone-other devices as well (cameras etc).

I made a quick test with two phones; Samsung Galaxy S4 and Samsung Galaxy S (yes, an ancient phone from year 2010 running Android 4.4). And yes! It works! Galaxy S4 is acting as a charger for Galaxy S!
