Many people do not know that you can charge your phone using another phone when it runs out of battery. It is a phone to phone charging. You can always have a power bank (travel charger) with you to charge your phone. But what if your power bank battery also drains out? This small technique may help you then.
To make it simple, let’s suppose you want to charge your phone using your friend’s phone. For this to happen, you require three things:
- An OTG cable
- A USB cable for your phone
- Your friend’s phone should have OTG support.
A USB OTG (USB On-The-Go) cable is used to access and transfer data to USB devices like pendrives through mobile phones. You can buy it from any online store or at the retail, pricing around 50 INR. Here is a preview of OTG cables at amazon.
You may already have a USB cable for your phone provided by your phone manufacturer. Many phones use it as charging cable. It has USB at one end and a small pin at other end. Now the third thing. Your friend’s phone should have OTG support. You can check the phone specifications online or in the phone manual to see if your friend’s phone support OTG.
If you have all these things, then you can proceed further to charge your phone. Connect all these things as shown- first your friend’s phone connected to OTG cable, then your USB cable, and then your phone. As soon as you connect, your phone will start charging. So next time you go out, keep ready a list of your friends who have OTG supported phones so that you can drain out their battery 😛
