no it only works on phones yes it works on kindle fire
No, unfortunately.
USB Type C
No they're not, they're actually quite different
One end of the charger plugs into the bottom edge of the kindle and the other end plugs into the USB port on a computer. Or you can buy an adapter to plug the kindle into a wall outlet.
The battery is a rechargeable lithium polymer battery. This battery is (likely) proprietary to the Kindle itself as you cannot access the battery without nearly destroying the case (I own one). The Kindle does come with a Charger that is a USB Cord with an AC Adapter that attaches to it.
no it won't.
If it the acutal kindle you can hook up the chord to it. I use my camera chord. something that fits in to the place u usually put the charger.
No.
