the Kindle should appear as a USB disk storage, just as it does to a PC. You could then use an Android app to copy from the phone file system to the Kindle.
I have ordered the above OTG cable, it is scheduled to arrive sept 13. I will report back then if no one else has replied before.
I recieved my cable today.
I connected the OTG cable to the phone and the Kindle to the cable and the phone could access the Kindle File System.
I also tried the Phone to a USB Stick and it worked too.
For more power demanding devices you might need a USB Y cable (male-to-malePWR-Y-to femaleCONNECTOR), or a USB cable to a powered hub (male-to-male powered hub CONNECTOR).
Hope it helped and thanks for the K.
