Yes, I have the Kindle Paperwhite. The cord that plugs into the Kindle plugs into the back end of this adapter. This unit them plugs into any standard household outlet. Very convenient for leaving at the place where you read most often. Personally I have found that the Paperwhite doesn't need charging everyday. After all the cover automatically turns the Kindle off when closed. Really a neat idea.
The adapter for the Kindle Paperwhite works as well as the one for the Kindle. Just add it to the cord, plug one end into the outlet on wall and the other into the Paperwhite, and in a short time you are reading again. Enjoy!
