Question 1

Which is better charger for the kindle paper white, this charger 9W or the 5W?

Accepted Answer

The 5W charger delivers 1 Amp of electricity, whilst the 9W charger delivers 1.8 Amps of electricity. With devices that have rechargeable battery's like this I tend to just use the 5W charger because it puts a lot less stress on the battery, and ultimately a lot less heat is generated from the battery (which may be a sign of overcharging, which can damage your battery as you charge it like this again and again). If you are okay with your device charging faster at the expense of a couple years off its lifespan, then go ahead. This is all ultimately the costumers decision. However I would recommend this charger for the echo dot, because it does not have a battery to overcharge and you can generally expect better performance when the echo is running off a 1.8 Amp charger than a 1 Amp charger.

Question 3

Will it work on kindle fire 5?

Accepted Answer

Yes it works on all my Kindle.

Question 4

Will this work for the kindle fire hd 10?

Accepted Answer

I really don't know.  I'm not familiar with the Kindle Fire hd 102.  It works fine for my Kindle Paper white.  I would suggest you contact amazon direct and talk with one of their technicians. That's what I did and he recommended this particular charger for my Paperwhite.  Maybe it works for all Kindles--I don't know.  Sorry to not be of anymore help.
