Kindle is not an output format. Output to mobi or output to AZW is what you want. You can also email personal documents to Amazon and they will convert them for you to AZW and send them to your kindle.
Kindles are a piece of equipment like a computer that will display certain formats. You must, in many cases, convert to the correct format yourself. Just keep in mind that it can be done and after you have done it it is easy
