These are Lithium Polymer batteries, old technology. The camera batteries are more than likely Lithium ION batteries which last a long time.

Did you get any responses to this -I am researching the same info -I have a Kindle 2 but Amazon only talks about 1st generation vs DXdharnellcohen@atlantaga.gov

ummmm...Li-Poly are the NEWEST technology for lithium batteries, Li-Ion is the OLD tech variation of lithium batteries.

I agree with you, they should add a connector to the charger so batteries can be charged without having to be installed in the kindle. I use rechargable batteries in my digital camera, and I carry them in the case for a month and they still have a full charge. I would think that the kindle batteries should be no different. My kindle battery wont hold a charge more than 3 days and it is only 2 months old! My camera batteries are 3 years old!

The USB outputs are standard, just different amperages. The 2.4 amp port should charge a Kindle using your USB cable. From what I read the Kindle takes less than 2 amps. The 1 amp port should also charge the Kindle, just slower.

This is the only device I have used so I cannot compare it to others. It stays fully charged for months. I just carry it in my bag and it only seems to really discharge when you are using it. You can attach it to your phone and make a call, or plug it into your phone and it will charge your phone. So basically it will charge your phone fully and then have some juice left. I haven't used it much. Seems to work well! Mine is a Droid Razr Maxx, and my friend used it on her non motorolla phone too, so I think it would also charge an Ipad or Kindle, anything with that same connector. So if you phone holds a charge all day, this will get you another day basically. This is the only device I have used so I cannot compare it to others. It stays fully charged for months.

ME TOO!!!!! They will not help me. I did find that my Kindle charger appears to charge it just fine. If you have one of those, try that.

A USB cord is supplied. You plug it into your computer or a USB adapter (not included) to charge . I bought a second battery and a generic charger off of eBay. So I have a spare charged battery that I switch when needed.

if the question is how is it charged. You must charge it for a few hours the first time before using it. It uses a mini usb cable that is connected to a computer. However, I have not had to charge since the initial charge. I guess if you type alot you have to recharge. The manual does not indicate this. You may have to pare the tablet and the keyboard regularly. I have not had to do this either.

I don't have a Kindle. But as I was told ..it charges things that have the micro USB cord plug in . Like we use on most of new smart phones today. It comes with a short cord. It has regular USB plug on one end. The other end has a micro USB cord. Which will plug into your device. Hope this helps .

Once charged, it lasts at least 24 hours. You have to hang it on the charged, so no, you can not charge it while using it. No additional batteries are required except for what come in it (sealed).

Would like to answer this BUT the unit I got did not charge anything. I tried it with my Kindle Fire HD and it never charged at all. May have been a defective unit I got BUT I returned it for refund.

I was also hoping to keep a spare battery on hand. Looks like it's a permanent battery. Two issues bad about that is: you can NOT charge one while the other is in use and once the battery no longer holds a charge, the unit is useless. Did I miss this information (permanent battery not replaceable) somewhere in the product description?

When my Kindle Fire would not recharge I called tech support, and they told me I needed a new battery. Bought a new one, installed it, and problem was Not solved. Turned out it was a problem with the mini USB plug on the Kindle - they wear out rather rapidly and will not make a connection. When I called back, tech support told me that the repair of this inadequate plug on the Kindle was more expensive than buying a new one.I would try to put your plug in and move it around to see if you can actually get a connection before buying a new battery.

I keep my iPad, iPod, Galaxy s3 phone and Asus tablet plugged in when not in use and I have not had a problem with overcharging. I don't have a Kindle, but I would assume it would be OK as well. The GadgetSys is the best charger ever.....

You may have to purchase an additional pick-up for that.Some Apple products have the pick-ups built into them,as do some of the Kindles.If the unit doesn't have the built in pick up,they sell them and I understand most phones and tablets will charge with these pick-ups.

Yes, you can charge your kindle. Generally speaking if you have a USB charge cord for any device, you should be able to use Jackery.

I just recieved my Kindle also. I bought the coverage because they will replace the battery once and replace the Kindle no questions asked if you break it!

Sure. Plug it into the USB port on the Kindle,then plug the other end into a wall socket. I plug it in and use it all the time. It recharges while you use it, too.

You MAY want to have it, but probably you do not NEED it. Technically, it would help you to charge your Kindle, but there may be an easier solution not involving adding the weight of this appliance to your luggage. It all depends on the charger which you are going to use in Europe to charge your Kindle. As far as I recall, all Kindles we have in my family came with "universal" chargers, that is, multivoltage ones, that can handle voltages from 110V to 240V. If your charger is a multivoltage one, then only thing you really need is an adapter (to be able to plug a charger into an European outlet). You MAY want to have it, but probably you do not NEED it.
