This is not appreciably faster than any other 1.8 or higher amp charger when used with my Kindle, Kindle Fire, Kindle Fire HD, various Android tablets, and other devices that have USB charging cables.
It also blocks an adjacent outlet. Why didn't they put the plug on the short end like the original black-and-white Kindle charger?
It is an exceptionally good deal when purchased together with a Kindle Fire HD on promotion, but the regular price is not competitive for a supposedly premium charger.
Additionally, it does not come with a cable, an omission that many people won't realize.
**EDIT** I appreciate the many comments, but Amazon promotes this charger as something that charges faster than other chargers, but I haven't seen any such advantage. At promotional prices, it's a good deal, but not at almost twenty dollars. Otherwise, look elsewhere.
**EDIT** When the review was written, the description of the item did not have this statement "Optimized for Kindle tablets: PowerFast is a 9W charger and will charge your Kindle tablets faster than the white 5W Kindle charger will." That line was added a considerable amount of time after I wrote my review.
