Question 1

What is the difference between the PowerFast and the Power Adapter for a Kindle?

Accepted Answer

I have both the Power fast and the power Adapter. All I can say is that the Power fast does charge the kindle faster than the other. I wanted to be sure so when both of my kids kindles needed a charge, I plugged them both in at the same time and found that the Power Fast one was one bar faster then the other. I really hope this helps. I am pleased with both. However, I am on the run the go all the time so the fast charger works for me. I also use it for my I phone too.  You can plug the cord into the base and charge the I phone too. Good luck>

Question 2

is this compatible with the new kindle fire hdx 7" tablet

Accepted Answer

This charger is a 9 watt charger, the connection is through your USB/micro USB cable which should have come with your Kindle Fire HDX 7" Tablet.Yes it is the preferred charger for your tablet. Other wall chargers are usually 4 watts, they will work but at double the time. If your Kindle is fully discharged the 9 watt charger will fully recharge it in about 4 hours. If you use your computer to charge your Kindle allow 8-9 hrs (overnight). I tried to charge my Kindle through the USB charger in my car once, it would have taken it about 20 hours to do that "not a preffered method, but it could work"I am a member of Prime and I stream video of movies and TV shows through my Kindle and I use a mini/HDMI cable into my 60" Flat screen, the picture is great. Using the 9 watt charger while I do this keeps the Kindle fully charged, and I sometimes do this for 4-5 hours at a time.The price is about right, so go ahead and get one for your self, you won't regret it. :>)

Question 3

how many charging ports?

Accepted Answer

It's simply an adapter so that the included charging cord can be plugged into an outlet. As it comes stock, you can only charge through a USB on a computer or USB charging dock.

Question 4

what is the length of the warranty

Accepted Answer

I couldn't find any warranty info on this.  But a return must be made within 30 days of shipping, which in my case is moot.
