How to tell which Kindle Fire you have (1st gen, 2nd gen?)?
Just bought a new Kindle Fire (not the hd) for my son, but it came with only the USB charger and I want to buy a wall charger too. Is the charging port the same for all of the models or does it matter which generation? If it matters, how do I know which one I bought?
Your Kindle Fire should be the 2nd generation. It's released in Sept 2012, and since then Amazon no longer sells Kindle Fire 1st generation. The 1st generation is only available as used offers.
Here you can find details on charging the Kindle Fire, the chargers, as well as how to optimize the battery life:
Hope that helps.
