If you are a person who prefers to go straight to the answer, without knowing the explanation, so now I can answer that yes, you can carry your Kindle with wall charger iPhone or iPad. All technical details to support this response are over post, but if you prefer to ignore them, I will not blame him.
As I said in the post about Kindle x iPad, Paperwhite decided to buy the Kindle so you can read my thousands of electronic books (e-books), but, despite the Kindle Paperwhite has the great advantage of the battery last for centuries (lasts up 8 weeks), one day you will have to load it. The Kindle Paperwhite unfortunately does not come with an adapter to appear so you can charge it independently of a computer with USB port , because it only comes with a USB cable with micro-USB output. Find it annoying to have to occupy a USB port on my notebook for this, addition to relying on the call note and wait 4am needed to fully charge the Kindle.
My question was: if I have the wall charger iPhone, I can also use it to charge your Kindle Paperwhite? Wanted to know the technical specifications of tension and ampere output wall charger iPhone, do charger recommended by Amazon, USBs ports and input specifications (voltage and ampere) do Kindle Paperwhite. I researched a lot and found the post “Tip: How to charge your Kindle Paperwhite without computer on and without blowing it up?” (something like: Say: How to charge your Kindle Paperwhite without the computer and without blowing it) that clearly responds to sim.
Technical Explanation
The Kindle Paperwhite need an average voltage of 5v to be loaded. Put a USB (either 2.0 or 3.0), the wall charger iPhone, do iPad, o Recommended by Amazon, they all provide an average output voltage of 5v, but they all vary in the amount of ampere. See the table below:
| Power Supply | Tension (volts) | Ampere |
| USB 1.0 | 5.0In | 0.5A |
| USB 2.0 | 5.0In | 0.5A |
| USB 3.0 | 5.0In | 0.9A |
| Wall Charger iPhone | 5.0In | 1.0A |
| Wall charger for iPad | 5,1In | 2.1A |
| Wall charger for Amazon | 5.0In | 0.85A |
How can we repair the comparison table above, what else ranges from all sources of supply is the value of the ampere. See what it means:
What is Ampere?
Ampere, according to Wikipedia, is the standard unit of measurement of intensity electric current. Can sum up all the explanation of electric current as the amount of electrons flowing from one point to another in a given time. The higher the ampere, greater the amount of electrons that are going through the site.
The electrical parameters are: tension (measured in volts), electric current (measured in ampere) and resistance (measured in Ohms). Mathematically they relate to the following formula:
| V = R x I Where V = voltage, And R = Resistance I = ampere) |
Then, to discover the electric current (ampere), derive the above formula as follows:
| I = V / R |
In other words, lower resistance, the greater the electrical current. This makes perfect sense, if it is too conductive medium, with little or no resistance, more electric current will, in the same time, if compared with other means more resistive. Making an analogy, spend a lot more water in a pipe 20cm radius in another pipe just 5cm radius, 5cm because it would be a more “Resistive”.
Looking at the picture again, we can say that the iPad charger circuit materials have lower resistivity than other chargers, because the amount of amps output is 2.1A, and that the USB port is made from components more resistive, 0.5A output.
What Ampere influence the load?
As explained above, the higher the ampere, the greater the electrical current and, consequently, the greater the quantity of electrons being moved in time. Conceptualizing a battery as a reservoir of electrons, We can therefore conclude that, the higher the value of electric current (ampere), the lower the time required to load it.
I have not studied in depth to see if the Kindle Paperwhite take exactly half the time to charge the battery using the iPhone charger, compared to the charging time using a USB, since the ampere charger iPhone (1.0A) is double the value of the USB port (0.5A), but I can say that it will take less time.
Conclusion
Although I have already answered the question in the first paragraph whether I can use the wall charger iPhone or iPad to load the Kindle Paperwhite, I repeat the answer: Yes, you can not use them to explode your Kindle.

Thanks for the very detailed explanation but I still had a question. If I charge the kindle with a charger that is 2A I cannot reduce the battery life? This reduction in charging time will not raise the battery temperature when charging?
It turned out that there are two doubts. Rs
very enlightening, Bruno. What good have people like you to help us with our doubts. long and healthy life for vc.
Congratulations on your excellent response was the question that had. very obigado.
Oi Bruno, I have a Kindle PaperWite. I wonder if to charge the battery using Samsung charger with output 5V / 550mA?
You forgot to talk about the power. The higher the current, the greater the electrical power consumed. So loads faster, but also warm the battery more than a charger 500mA. You can load (I even carry) with 1A charger, but the risk of battery life reduce large eh. It all depends on equipment capacity. I know the Kindle project, but it is written current max 500mA. Above that may occur but damage, although it is not the short term and plug in a 12v transformer.
So, even if the Kindle paperwhite (5,25In), I can use any charger that has 5.0V?
These tips apply to the new basic Kindle 7 generation?
Hi Good Night bought a kindle and I am in doubt to carry it with my Samsung charger could help me please the charger at the entrance says it 200 and the outlet 5
from what I understand I can use if my iphone is not the 6, because this comes with a wall charger 10v. That? Another question: It can exchange files and kindle ipad? There is a cable for this?
Hello Anita!
The wall charger iPhone 6 is 5V and, therefore, you can use to charge your Kindle.
For the exchange of files between the Kindle and the iPad you must use a program on your computer. If the book is protected, I suggest you install the Kindle Reader app on iPad. There is no specific cable to connect the Kindle on the iPad. That does not exist.
Hope this helps.

Oi! This information also apply to the New Kindle? Thank you.
Hi Bruno, when we purchased our kindles and my iPad the devices came with a white cube that plugs into the wall and a USB cord that in turn plugs into the cube. Is the white cube the charger you refer to in your article and the subsequent comments? If yes, with help of an adapter plug can we use this cube to charge our devices at 230 V and 50 Heart? Thank you.
Hello Bruno!
I'm sorry if it is already tiring pra vc, but I wonder if I can use an adapter from Motorola 5.1 in 850 mA to charge the Kindle touch
Thanks for the post!!!! It helped me a lot!
Hello, friend! Thanks for the great post, enlightening. Here I have a motorola charger that can be adapted to the USB cable and it contains the following information: Input 100-240v ” 50/60Hz
0,2A
Output: 5,1In – 500mA
I could use it to charge your Kindle? Is there a difference between models of Kindle?
Thank you!
I have a motorola of 5.1V and 850 mAh. Este serve?
Hello Fernando.
You can use yes. 5.1v is within the safety margin.

I have a samsung charger output: 5,0V 1,0A, I use the Kindle Paperwhite quietly?
Helped me a lot… plus save on buying a wall charger.
I have a charger with the exact output of the charger Kindle ( 5In – 0.85A )…
Thank you !
Oi. I use a 5V 2A charger to charge your Kindle and is loaded in a very short time. This is the same charger that Follow the Galaxy Note 2 phone. I charge my Kindle Paperwhite with this by the way.
good morning have a charger 4,75 V e 0,55A. I can use? I think it will just take longer to load, thank you
Olá Angela,
Theoretically you can use it yes, because the output voltage is less than 5V and, therefore, not burn your device.
The problem is the question of the range I have highlighted in red in the above post.
If your source is reporting that delivery 4,75V, and consider it to 0.25V may vary more or less to, then we have a maximum of 5V and 4.5V low peak.
This variation does not burn your Kindle, but honestly do not know if I could load it when you were at 4.5V. Only testing even.
I have helped in some way.
Abs!

Thanks a lot!
Clear, objective and useful. Thank you, Bruno! Shared, clear! Hug.
Bruno, congratulations for objectivity and clarity of the post, and thank you, helped me a lot.
I have a charger from Motorola (5,1 V e 0,85 A) that will serve perfectly to load my dear Paperwhite!
Olá Helder!
Glad the post helped you. Apparently, saved when buying a charger.

Olá Bruno. Congratulations Post. Planned to buy the adapter from Amazon, I think is an abuse..
Here is 2 samsung:
2A and 5V one another 4.4 V 0.4 A.
what is the best pro paperwhite?
the 2 serve?
James,
Use the 5V and 2A that has values very close to iPad. The other is weak.

Thanks for the excellent post, I found the best network in the face. Good money saved by not purchasing the original adapter and use my adapter Nokia Lumia (5In, 1A). Now the savings will help buy a good and legal cover for Kindle.
Goose, eu tenho um Kindle, and I wonder if it is possible to charge the battery on my kindle for my notebook (ele é bivolte) ? But the kindle is 110v.
Hello Suellen!
Are you wanting to charge your Kindle using a USB port on your notebook? Se for isso, yes you can.
Now, if you are wanting to load it using the power of your notebook, ai não. First because I believe that the connectors are not compatible and, second, the source should provide a higher output voltage than 5v, then, as mentioned in Article, can not.
Abs!

Post EXTREMELY confusing. Very bad English.
Face, sure that the ipad is 5v? The charger from my Ipad 1 ta showing 10v …
Hello Paul!
You are not distracting tension (in) with power (in)?
IPhone Chargers have 5w power, but 5v supply voltage.
The iPad have 10w of power and voltage v 5.1.
Check out the information straight from your charger and see the information described therein.
I hope I have helped solve this question.

I got a charger from LG, and the output of these is 5.1 V, e 0,7A. From what I understood, tá sussa a lo Kindle, nor?
I always had issues of charging phones and devices in the past until I got my Galaxy Note 2. The Note 2 came with a 2A adapter and I was able to charge my other Micro USB devices with this Adapter in half the time. According to this article, yes, having more Amperes gets more juice in the battery quicker than lower Ampere adapters. I use an external battery charger for my Note 2 with a spare battery and It charges from 1% to a 100% in less than 2 hours. Charging a phone while it is turned on is never true 100% charge. Can you have food while running at the same time!? Same concept here. Hello.
Hello Khaja!
I really appreciate your comment! It’s the first comment in English here at BrunoCunha.com and I learned things on it.
Thank you for collaborating with your experience!

This post helped me a lot and has content, really thank you!
Saved R $ 79.99 and have already made the test. It worked perfectly! Pedro valeu!!!
Good article.
Have a question: I have a 7 port USB hub attached to my computer and a 5V, 3 Ampere charger running the hub. Will it also be safe to charge the Kindle Paperwhite from this USB hub.
Hello Janus.
It’ll be safe, because your USB Hub will provide 5V on each port.
Thank you for your comment!

Fantastic, post very well written and easy to understand, Besides being extremely inportância for users who use a lot of their kindles, that is my case. Thank you very much!
