Make your own Charging cable for MFC Dongle - So easy!

A, For Apple 30 Pins Cable

To have USB charging work in the OTG cable, we have to connect +5V (red wire) to pin number 23 of the connector. The problem is that usually connector don't have this pin inside OTG cable. So you have to find a new pin and put inside connector and soldering as below:

Materials you have to prepared :

A. 1 pin
B. 1 USB cable

B. For Lightning connector

We have 2 ways to do for Lightning cable

A, You can find a convertor adaptor plug to 30 Pins OTG cable, then can direct use (30 pins to 8 pins convertor adaptor), We tested original one should be working perfect
B, Need to connect pin number 4 on both sides of the connector to +5V (red wire from another USB cable) ,GND can connect to any GND (usually pin 1 and 8 of connector)

Materials you have to prepared :

A. 1 small wire
B. 1 USB cable

C. For Samsung /HTC Micro connector

A, Need to connect pin2 to GND with 1 resistor
B, When you using , you have to input the USB to PC or Wall Charger. Anyway you can put a switcher to control this resistor (Means if you need charging the switch on, if don't want charge then switch off), i will find a new way later

Materials you have to prepared :

A. 1 64.9K Ohm resistor
B. 1 USB cable
(BTW, the pic is 100K resistor i made for sony )
