How to Power your USB devices from your mobile
When you put your mobile for charging, you connect mobile to charger using micro USB port, and using OTG cable (On Travel Go Cable) $5.79 Best Buy you can use the same micro USB port to connect to any USB device 🙂
Remember that your mobile device must be compatible with OTG, you can refer to documentation of your mobile or just check it on internet. Mostly all latest mobile devises with Android 4.0 and above supports OTG functionality. as example my Ximoi Redmi 2 supports it.
To check the compatibility you can get into shop, plug in the OTG cable to micro USB port and simply connect a pen drive to your mobile or tab, if your device is able to detect it then you are ready to go 🙂
Check OTG cable price on Amazon (Normal price is around $5)
