Energizer XP18000 Universal AC Adapter MSRP at $180 (Amazon currently has it for ~$160).
At 4.5x7x1.6 inches, it'll complement your Kindle Fire very well by sticking it on the back of it (Kindle Fire is 4.7x7.5x0.45 inches).
It comes with a microUSB adapter, so no need to utilize Energizer's free tips program (of which you still have to pay ~$4 for S&H).
I use this for portable charger for primarily my laptop since I'm a commuting student, and some classrooms don't have plugs available; figured maybe someone wants one specifically for their Kindle Fire.

For that price you might as well just buy another Fire and when one goes dead turn the other one on.

glad i wasn't the only one thinking that lol
but it does work on more then the kindle so perhaps it's worth a little more merit then that... still more then i would pay for a backup battery

If it doesnt make the Device look fat or thick than this would be amazin

New Trent battery
Here is the battery i carry as a backup
http://www.amazon.com/New-Trent-iCr...Z64Q/ref=sr_1_1?ie=UTF8&qid=1323053218&sr=8-1

I just bought another New Trent battery
(cant post links yet, but its the New Trent IMP70D)
It was on sale last week for $29.99. At 7000mah it should be able to charge the kindle fire more than 1.5 times and at $30 it was a steal and will definitely be useful on my next overseas trip.

So that Trent battery is 11000mAh at $99.95, or $9.09/Ah, and that XP18000 is 18000mAh at $179.99, or $10.00/Ah, retail price.
At discounted (Amazon current price), it's $7.00/Ah and $8.80/Ah respectively.
Trent 11000mAh battery is a better value for all purposes, for small electronics charging. If you want to charge other electronics, like laptops, you have to pay a premium (damn).

Where do you all work and go to school where there are no outlets to plug into?
The fire lasts 8hrs+ for me. If you use it heavy maybe a lil less, but still no need to carry batteries unless you are in a long plane ride or bus ride, etc where you can't plug anything in. Any job/school/house has outlets.

I think I personally made it clear in the first post.
If you want more details, I commute, about 4 hours a day. For that, and in-between classes downtime, I use my Fire, which is *generally* more than enough // not worth charging. My classes, I use my tablet PC, which lasts ~3 hours of battery life, hardly enough for one day of classes.
Depending on the seat I get, I might not have access to the outlet (or some classes straight don't have outlets; crazy they're spending hundreds of millions of dollars upgrading public image, but not classrooms; that's the current private higher education for ya), and I desperately need external battery for my tablet PC (e.g. the Energizer XP18000), since OneNote > Paper.

I have more than one device that I carry with me. With the battery and a microusb cable, I can charge all my devices wherever I am and whenever they get low on power and don't have to carry the a/c adapter and worry about whether the outlet is close enough or whatever.

thats the one im getting next pay day i think it will keep my phone charged and my kindle charged for full day of on the go mobile hotspot on the phone and near constant use with with wifi on and lots o youtube.

How long does this run your laptop for? I do IT for a string of verizon stores and, at times, my laptop takes a battery beating and plugs are a PITA to get to. This looks sleak and compact so it should be unobtrusive enough to carry in my bag when out fo town.

Monoprice 2800mAh portable battery box

I just got a portable battery box (2800mAh) for $14 from monoprice. (LINK)
Nicely built, relatively small, and about to test whether it will give me 1.5 full charges as mAh would suggest (2800mAh / 1800mAh on HOX = around 1.5 charges).
Box itself doesn't come with any charger, but is able to be charged by any charger with Micro or Mini USB connector (yep, it has 2 inputs).
Output is a male MicroUSB connector that fits HOX nicely (duh!).
Output: DC5.0V 800mAh

I'd imagine if you want to use the phone while charging from it, you can connect them with a female-male MicroUSB connector.
The charger has a button that shows the charge level of the box with 25% increments (4 lights).
Has another light for "FULL".
As soon as I connected the box to HOX, phone immediately showed that it's being charged, as if from the regular charger. Not sure what the current is, but it may come across as slow charge (USB port charge) as opposed to AC charger.
So far I tested the charge over 10 minute deep sleep period, and I got this:
With the box, in average HOX charged for 2% every 10 minutes.
That would suggest that it would take this box 8.3 hours to charge HOX fully, which isn't bad at all, considering you're free to use it while it's charging.
Over next day or so I'll try to completely discharge the HOX and charge it overnight from the box. I'll see just how much this box can spit out.
---------------------------------
EDIT/REPORT:
I discharged my phone to 5% yesterday, disabled wifi and BT, and connected it to batt pack to charge overnight.
It turns out that this batt back is crap.
Overnight, when phone was in deep sleep with wifi/BT off, a full battle pack charged my HOX only by 55% (I charged the batt pack before using it). Even considering some small drainage during charge, I'd say this pack actually acts if it had just over 1000mAh or so, nothing close to 2800.
Oh well, gonna return it and keep looking.

shouldn't this be in the accessories forum?

That's a good option too, although I actually like that monoprice's sticks right into the phone, so you don't have to carry a cable with u.
Also, it seems smaller and cheaper.

I know of certain defense organisations that allow the fixed connectors but not those with detachable cables. Disallowing the cables reduces the risk of the cables being used for data transfer.

It's a security standpoint from Defence services (IE: Australian Army, etc) who wish to minimise security leaks. A data cable can be used to link up other devices, not just the charger.

Okay, and I guess if I were flying in outer space, my suit was venting air, and the only thing that would save me is connecting a batt pack to a phone - in that situation a cable could freeze solid to a connector on the batt pack, making batt pack unusable, and thus killing me.

WRONG!
That's when Iron Man comes flying to the rescue thus saving your life and getting an autograph that you could sell on eBay for some money and covering your costs of the HTC One X.

OK well, turns out that this batt back is crap.

Im going to try this one and ill write about it, it looks good to me and theres a review on the site

The problem with the types of solar charger that you posted is that they charge slowly. And exposed to direct sunlight, it might heat up too much and damage the internal lipo.
IF you just need a power source, get a portable battery. They are cheaper and works better in the long run.

Correct about the solar panels, at least with current technology you just can't get enough energy from something this small to justify the added complexity/weight/price.
Unless you are away (as in no mains and no "car" power) for weeks they aren't worth it - and if you are away you still need a more serious panel.
Just get one of the external "power packs" and top them up quickly over a few hours when you get the chance.
As a side-note the battery in Note is pretty big already and I suspect the charging circuit from the phone is quite far from 90%+ efficiency. Bottom line you need to get a beefy external battery; I'd say 5000 mAh is bare minimum if you want to get you through the day if you use the phone much.

So the 10.000 Mah would be good, if i get the chance to get a refund, as the delivery is already 20 days, i am going to buy that one.
Regards, Tomaat

Also, this will ruin the battery, when it isnt recharged with the correct amount of electricity right? Just as when you charge your phone with a car-charger og usb from the computer..?
In my experience, if you want a fully charged lasting battery, you need to charge with electricity from the wall...!

Huh?

This is what I think of Solar Charges, if someone is interested. This is a nice small article about how good they actually are.

Let me know what you think

You need a NEWTRENT. IMP1000
I've one and it charges 4:5times its great

I am not Baekdal, but I am a subscriber of his work. I just thought that it might have been interesting for the discussion mentioned in this thread. I also consider myself an environmentally conscience person, but as the article points out not everything that looks green is green .
The solar charger is much less environmentally friendly than the electrical grid, which means that it will not save you money nor will it save the environment.
I'm glad you've enjoyed it.

Brother I got a similar equipment and is not as great as you pretend to be.
Sure the price is cool, you find it with 5 dollars on wholsales but I bet it doesn't have 12 Ah, if it has 10 Ah is good!
Second: the lights are not indicating the right amount of energy recharged.
I discharged completely, and started to charge with an 700mAh charger and the blue lights went on in a 2-3 hours interval and this is not possible.
Also is not possible as you say to recharge 12 Ah battery with 1Ah recommended, in just 3 hours as you mention.
This device needs like 10-12 hours with 1000mAh to make it full, and as I said the light indicators are not precise.
When I first got it, It had some power in it for test I supose, but it was showing all 4 leds lighten up. I powered my 33% Samsung Tab 2 7inch and started to charge till it reached 77% and then died!
I put it to recharge! In few complete cycles the life time will improve, but I don't think is able to recharge a 4Ah tablet 2 times! If is getting one time is perfect! Not with the tablet open, at least!
Another thing people should know is they should use their original cables, the connectors don't fit on my tab, and on an old Sony Ericsson phone. Both of them are the wrong size!
The design is nice, the price is good, but I don't think is a good battery pack!
Another thing people should know about it, is not multitasking. If you plug in a Phone and a Tablet in the same time, is dying fast, so.. you must choose!
I recommend this product for his low price! Is not so big either, but the cables and adaptors are junk.
Good luck guys!

But everything's made in China?! (j/k, I know what you mean.) Most of the stuff sold on the ecommerce b2c sites are of the Shanzhai variety).
But isn't that always the case, you get what you pay for.
When I bought my Note 8, they offered me a deal to buy the Samsung 9000mAh power bank for about 600HKD, which is about 85USD. Expensive yes when compared to the typical cheap China stuff, but then again, I don't relish the thought of battery acid exploding on my leg. Though some might. I guess.

CHOETECH T513 Wireless Charger Review with Coupon Code

I have tried CHOETECH T511 before, basically speaking, this T513 is very like the T511 that they released on 2013, same carve on the pad, same smooth feeling when i touch the pad, and same led indication when connect the power source on. The LED light is smaller and less bright than T511 square version, this is a small improvement but according to the review of T511, this might compliment many buyers who want to use it in bedroom, and it has no sound beeping like the old version.
2 improvements:
1. The design is more fashion with shining silver side, add some element of metal.
2. The solution has 3 coils inside, it makes the charging area much bigger than 1 coil solution. Any place on this pad is the sweet spot so you can just put the phone on the pad and it starts charging, very convenient.
This pad seems too smooth to place the Nexus 4 like the old version, if the table is not very flat, it will slide a little bit. But it has no problem of draining battery after charging complete. And it generates less heat than most other brands, never higher than 104 °F.
Here is the 30% off coupon code from Amazon: IAWP6WRN

Look at the CHOETECH spammers with low post counts pimping the CHOETECH brand. I actually owned one and it's very poor quality, weak solder joints , fragile plastic parts. I feel obligated to speak out against this BS hence my post.

I have the one coil version with no problems. Got it for $25 if I remember correctly so i'm not complaining.

I owned one of their earlier devices. It wasn't bad for the price. However, compared with the official Google Nexus Wireless Charger, there were some serious overheating issues associated with the Choe.
To be specific, my device would heat up to about 50-70 C (depending on how long I'd leave it on the charger), when my device would be in deep sleep. I can't imagine how hot it'd get if I was texting or using hangouts intermittently while trying to charge it.
Also, with the choe, I found it annoying that my device slipped all over the plastic top and not easily finding the "sweet spot."

You talking about me? Heh. Unbiased. LOL!

I've got 2 choe chargers. Can't remember the model but they work great. No over heating and placement hasn't been an issue.
Sent from the jaws of my Hammerhead!

Anyone having this problem?
I got the T513 based on a recommendation that I saw in a Verizon Note 3 "Wireless Charging" thread... for the intended use of - you guessed it - wirelessly charging my Verizon Note 3. The reason it was recommended was due to the larger size of the pad (large phone needs a large pad so it doesn't fall off), and the 3 coils.
Today was the first day that I've used it at work. I put my phone on it (blue LED came on), and when it got to about 98% battery level, it seemed like the charger would turn off (LED turned off), my phone would wake up, and then charging would start again (LED came on)... and would repeat this cycle about every 30 seconds.
Is anyone else seeing this behavior?
It seems like my phone is saying "OK, I've had enough charging" and ending the charge connection, which is then re-activated within seconds, only for my phone to say it's had its fill again. Weird.
I really don't want it to do this. I don't mind so much at work, since the phone is in plain view, and I can take the phone off the plate when I see it start to cycle like this. However, I'm curious if this same thing is happening while I'm charging my phone at home while I sleep.
