The Kindle Fire HD has two Ports - a charging port and a HDMI port. If your Kindle does not have these two ports then this cable will not work on your device. This does not work with the Kindle Fire HD 2013 generation and Kindle Fire HDX (new generation) as the HDX does not have a HDMI port.
This product would be ideal for individuals who want to connect their Kindle Fire or Amazon Kindle (HUDL) device to an external TV or monitor.
