[Q] charger replacement for kindle

can i use any charger that can fit into my kindlle fire?
i have a charger of LG optimus one and it fits exactly.
i cant find shops selling kindle fire charger here in the philippines.

the original has 1.8A - would try to get one that has around this value
with a charger under 1A i'm pretty shure you'll get charging problems or at least it lasts very long
basically you can use every usb charger ...

Yes you can as long as a charger has equivalent current as the original charger.

I lost mine and just been using the iphone wall charger with the mini usb cable and it's been working fine. Does charge pretty slow but that's all i can do for now.

Any USB charger will work, but one with less current won't charge as fast.

No... I got a charger off ebay and it said it was for the Kindle Fire, but it was only 1000 ma. and I had all kind of problems, There are several threads on this already..Get one at least 1.8 amps and you'll be ok..

The Kindle Fire will recharge from a powered USB hub or computer just fine, and that's only 500 mA. The USB spec doesn't allow for anything greater, so you may run into incompatibilities with other chargers since compatibility is the main reason we have specs. Hopefully manufacturers are talking to each other about how to make fast chargers, but, given Houndog101's experience, it doesn't seem like that's always the case.
The Kindle has a 16.3 W*h battery, so you can calculate how long it'll take to charge given any current (5V * current = Watts), if you account for the loss due to the Kindle being on at the time. A standard USB port is going to take at least 7 hours to fully recharge the Kindle, and probably more like 10+ if WiFi is on. So I'd definitely go for a 1.8 A charger, and hope for the best. Don't spend too much since it might not work unless it's specifically made for the Kindle.

Belkin F8Z630 charger
I've bought several of the Belkin F8Z630 chargers and been very pleased with them. Not cheap, but they deliver a solid 2.1 A at 5 Vdc, they can handle any input 100-240 Vac (basically worldwide usage), and they have a nice rotating plug feature that is handy in some tight spots. Works great for charging the KF quickly.

I found one in my car from an LG that chargers it just fine, and in a timely manner.
What happened to the stock charger? The one that cane with my fire did not work at all

Looking for an additional 1.2 amp charger.

I tried calling Google Play device support. They said they don't replace chargers, and I should just use a standard micro USB cable and wall charger. The problem is, I have not been able to find a 1.2 Amp charger of any kind. Anything lower will charge the phone more slowly, and from what I understand, unless it's properly shorted out (I think), anything higher will not necessarily work properly with certain devices.
Can somebody please help me find a good replacement charger that won't charge the phone more slowly than the one the phone came with?

I believe Ipad chargers do 2amps, or try a 1amp charger since i haven't seen more than 880ma from my battery widget when charging it.

What about this? http://www.amazon.com/gp/product/B0073FCPSK/
USB Port 1 (Designed for Apple products) Compatibility
iPad @ 2 Ampere Max.
iPhone / iPod Touch @ 1 Ampere Max.
Others phones / GPS / Tablet etc. @ 0.5 to 1 Ampere Max. (May not support charging of some devices)
USB Port 2 (port close to LED, designed for non apple products) Compatibility
iPad @ NOT Compatible
iPhone / iPod Touch @ 0.5 Ampere Max.
Others phones / GPS / Tablet etc. @ 1 to 2 Ampere Max.
Would the non-Apple port work?
Somebody mentioned this to me on another forum: you gotta be careful with those dual chargers. sometimes the higher current port is limited to apple devices (i think they have a couple pins in the cable shorted)
What exactly does that mean? The product I linked to, does it have this problem?

Disregard, forgot what section I was in!

Just do what was suggested at LL.

that was not helpful at all. I made a topic here for a reason, LL was being completely unhelpful

Anybody know about that PowerGen Dual USB charger I linked to? I just remembered I actually already have one of those. It'd be nice to just use that one.

I'll be honest. I don't like that Blackberry charger because you can't remove the USB cable from it.

Get the amazonbasics wall charger is 1.2 amps.

No it's not gonna hurt the battery. The phone (or better a battery controller) controls the current that reaches the battery. So no matter how powerful a charger would be it will not charge above a certain current.

Thanks. But chargers are easy to find. What is difficult to find is a USB cable to work. You'll see in the thread I linked on the first post, lots of people are having challenges with finding USB cables to work even if a charger is well above 2 amps. Even using the stock LG charger, no USB cables seem to work except the one that came with the phone, to eliminate the "slow charge" icon and allow around 1500mA of current to be drawn from the charger like it should in a fast charge..
what cable are you using with your new charger? And do you get the slow charging icon?

I think it all boils down to the charging base... I have used the LG, various Htc and Samsung base units with all kinds of mini & micro USB cables without any issues... The base units are rated from 800mA~1.5 and have not had any slow charging issues... I've only experienced the slow charging when connected to the PC or some car chargers...

I used to run a 1.5' usb cable from monoprice and the GPS on my phone would discharge the battery faster than it could be charged. Now the phone charges so much faster.

I have yet to have a problem with any of the generic monoprice cables and wall charges I bought a couple years ago. Only time I get a slow charge notification is using my 1a car charger. My Optimus G and HTC One X chargers and cable work fine as well.

IT IS NOT THE CHARGER!!
It is something in the cable. And good luck finding one. If you use the included USB cable that came with the G2, then it will charge on ANY charger "normally" (fast charge). If you use ANY OTHER cable, it will slow charge.
I don't know what is in the cable or why it makes a difference, but none of my USB cords/chargers work unless I use the INCLUDED USB CABLE.
I had a thread on this already somewhere in the General Area I think. It REALLY sucks because I have TONS of chargers and cables. I have some at work, home office, bedside, 2 in my car, friends cars, etc. I DO use Wireless Charging at night and luckily the phone has a huge battery to last through the day.
There IS a problem here but my thread got ignored like, "I don't see a problem here, just use the included cable". Well yea if I stayed home all the time. My work makes me travel for work so I have to make sure I remove the 1 working cable and carry it with me EVERYWHERE. What a pain in the butt.
Has anyone tried on custom roms to see if perhaps it is something just on the stock software telling it to go Slo-Mo.

My Verizon non usb attachment cable charges fast. My OEM Spectrum cable does as well. My dual one amp car charger charges slow no matter the cable, and my works Motorola and Kyocera cable charges slow no matter the connection. I have a couple Samsung's I need to test. I do not own any generics. I have not tried other combos.

LG Spectrum cable does not work, slow charge, my fault.
However, the straight plug from my new Verizon car charger does work, the USB port also (ONLY with G2 cable so far[tested lg spectrum, Motorola, Samsung, and Kyocera. Older cables]).
Recap: So far ONLY Direct car charger or USB G2 cable has fast charged. Must be chipped or using some different wire combo?

Ok. I can confirm that the cable used for the Nexus 7 (2012) works.
Also, the original cable for the Samsung Skyrocket works.
Works meaning fast charge.
I can't gurantee that this is the cable, but my skyrocket cable does look like the top cable here:
http://www.ebay.com/bhp/samsung-galaxy-s-ii-skyrocket-usb-cable
(Charger looks like it too, but the charget won't fast charge G2)
Edit:
The Skyrocket was really picky about cables/chargers. If it didn't have the correct one, it would wakelock. Maybe there's something with the way it's wired that makes it good for the G2 as well.

Yeah, I'm not so sure about that. It may be the software in the phone that is causing the issue. I had to replace my car charger so I picked up a rocketfish 3.0 amp charger. When I originally used it, it was ridiculously fast, literally 30% in about 30 or so minutes.
Now, here's why I don't think it has anything to do with the charger cables. When I got my phone, I kept putting off doing the first update because I wasn't sure if I was going to root this phone. During this time, I got very good charging speeds from my rocketfish 3.0 amp car charger and many of my other rapid chargers. When I decided I wasn't going to root, I went ahead and downloaded the update. Now, unless I'm using the cable that came with the phone, I get the slow charging message with every single charger. I went from 30% in 30 to about 10% in 30 on my car charger.
I may need to pull out my tinfoil hat, but it would be a pretty huge coincidence that all my charging woes began with that update.

Yea something isn't right. I have a GNex, G2, Nexus 7 2012 and 2013. I always check for AC charging in Settings>Status. It will say AC or USB. When I got my Nexus 7s I replaced all of my chargers with fast chargers. For 2 years I've been fast charging. I got 3 different fast USB chargers on my desk, using the existing setup, Everything fast charges except the G2. If I use the included G2 cable, it will fast charge off all of them. The same with ALL of my home/office/car/travel chargers.
I can only get it to fast charge when I use the included USB cable.
Its something magical with that cable.

I haven't even unwrapped the charging base and usb cable that came with my G2, they still remain in the box. I have been using the charging bases from my Nexus 4, L9, Htc One X, Motorola Atrix and a GS3 through out my house and have mixed cables from god only knows where and all of them work. I get no slow charging from any combination. Even using mini usb cables with micro usb adapters attached and they all still work. I've checked all the output voltages and the lowest one is 800mA. Granted my D801 is rooted, but no custom rom as of yet.

Have you gotten an OTA update?
I'm on the Verizon model. The other guy here said he only started having problems after the Verizon OTA.
-sent from my LG G2 using XDA Premium 4

Here's my theory,
There are chips either in the battery, the transformer, or both. When the phone doesn't detect what's required, it gives a slow charge message and reduces the charge speed. I have had previous phones with batteries that had built in chips that I had to buy because the generic batteries without the chips wouldn't work as well. I haven't taken a good look at the battery, and the transformer seems abnormally large, when I get a chance and some spares, I'll probably take them apart.
My tinfoil hat is telling me that LG is trying to rope us into buying first-party accessories, but it may also be a way to regulate battery health. Having a non-removable battery, it may be a move by LG to extend the life of the battery as long as possible.
Also, I just rooted my phone and so far no change. I will try the car charger tomorrow.

No updates from Tmobile as of yet... I can only imagine the frustration though. You would think LG would have made charging the phone, regardless of the model more standard across the board.

800mA is a slow charge... You should average 1700mA. Our cable is five pinned (if that matters). I need grab the mA reader app again. Now we know there is kernel check for flux ect. I want to know if the cable is pre chipped as well for check and regulation, isn't too uncommon. I'm beginning to lean more on an over aggressive kernel check though or possibly a combo of kernel and certain chip model check. I just find it odd my straight Verizon car charger and only this cable is working for me. Gonna check car cable pins in the morning. Verizon here, OTA taken. Did not check before.

Turns out the Nexus 6P can be charged via Quick Charge afterall

It was disappointing to find that the new Nexus devices don't support Qualcomm's Quick Charge 2.0. I would have thought after all of the demand, especially with the Nexus 5 that Google would make it a requirement. So I saw this article on Droid-life and thought I should share as a general PSA to everyone. They did tests and found that the only quick/rapid charger that can charger nearly as well as the more pricey stock charger is Tronsmart's Type C car charger.
Unfortunately I can't post as links as I've been a lurker for too long and not enough posts, but they have it over at droid-life if you want to check it out. Someone could probably even comment it for me.

http://www.droid-life.com/2015/10/19/nexus-6p-nexus-5x-quick-charge/

Except it charges at about half the speed of the dedicated 15W/3A USB-C chargers.

I bought one of those tronsomart car chargers last week. Seemed like an adequate charger until I can get a suitable one that can supply 3A. The fact that it had a USB port so my wife can plug her iPhone into it sealed the deal. It's definitely going to be better for me than the car chargers we have now, that's for sure.

Get this. I've had 2 of them for a year or so and they charge my N6 faster than any QC2 charger I have. No usb c, so if you really want that you are SOL but I don't think that it will matter

I must be missing something? Down the bottom at Update 3 it says that the Tronsmart was almost equal to the stock charger and one of the tests has the stock at 2642mA and Tronsmart at 2511mA.

[Comparison] Updated Charging Speeds Comparison (QC 2.0/3.0, 10W Qi, Standard) S7/S7E

Method:
First I used my phone until the battery was below 15% in order to get a better picture of what the charging would look like over almost a full battery cycle. I did not start at the same battery percentage for each test because I did not find any benefit to doing so. I original did this for uniformity, but it did not make a difference after trying it using the more accurate equipment.
I then cleared my history in the Battery Monitor Pro Widget (BMW Pro) recording app which was used to log the battery [mV], battery temperature [F], time, and battery percentage changes. Once this was done I plugged in my USB Power Monitor, turned airplane mode on, removed the case, and let the phone charge. I started logging the data via my power monitor once the phone showed it was charging. From this point onward I let the phone charge without interrupting it until it reached 100%, then I let it charge for another 10-60 minutes to see if it was still drawing power from each charger. Once all of this was done, I exported my data collected from BMW Pro, emailed it to myself, and pasted it along with the USB Power Monitor data into an Excel spreadsheet. All of the data was then delimited to separate the clusters of data due to the way they were recorded, and subsequently graphed. The USB Power Monitor recorded data points every 0.36 seconds, while the BMW Pro took recordings every 5 seconds because I was having issues with the “real-time” recording option in the app working correctly.
All of the data was then graphed into the nice figures you will see below; each color reflects the same variable across all of the graphs to make reading them easier. I included a legend at the top of each set of graphs which should also help make it easier to read the data.
The most interesting part of this test is how cool the S7 Edge stays while charging, and the very marginal difference in overall charging time between QC 2.0/1.0. A 15-minute gap is marginal at best given the ‘big improvements’ Qualcomm claimed when launching the newer standards.
When conducting the wireless charging tests I think there is some error in the Samsung Fast Wireless charging data, so I plan on redoing it at some point. I already redid the Choetech one because it has a similar strangely long, but now it seems more in line with what I initially found before using the newer testing equipment.
I wanted to also quickly point out that both my HTC 10 and S7 Edge keep pulling current even after the phones show they are 100% charged. I’m not talking about a tiny amount; they both pulled ~1-5W+ after hitting 100% battery which is A LOT considering they are reporting to be fully charged. I verified this using 3 multimeters just to be sure. It appears as if Qualcomm, or the OEM’s are falsely reporting when the phone is actually charged, or there’s some other shady things going on here.
Another thing I wanted to mention is how the S7 Edge is so consistent in the way it charges the battery. It could be due to the lower rates Samsung uses (9V/1.67A max which is 15.03W) vs the HTC 10’s up to 18W that I’ve seen it pull. Just take a look at how the S7 Edge charges using QC 2.0 compared to the HTC 10 with lower temperatures, similar times, and a much more consistent overall charging curve.
If you look at the Tronsmart & Choetech QC2.0 tests, then you might notice the large difference between the two. The Tronsmart charger has a harder time holding onto the proper voltages, therefore it bounces around more from ~8.92V-9.03V (a 0.11V change) while the Choetech one ranges from 9.077V-9.092 which is a significantly smaller 0.015V range. The power control chip is responsible for controlling these voltages, and clearly the Choetech one has a better chip in it. This is especially important for external battery packs where efficiency really matters due to the limited amount of power they can store.
Equipment:
These tests were conducted using a series of different chargers. The same brand was used for both Quick Charge 2.0/3.0 tests to minimize experimental error; This trend remained the same was also done for the wireless charging tests

very good stuff!
maybe you could also record the heat at the hottest spot of the phone during charging? I think qc3 has the same charge rate but its able to change voltage to reduce creating waste heat compared to qc2.0.
my main concern with the s7 is the battery life, i know it won't last me a full 18hr day so i really need a portable fast qc2 charger that is pocketable, so maybe 5000mah, but have not seen such a small qc charger tho

Excellent post and well-made graphs. Thanks for your efforts.

well done. good info here.

maybe you could also record the heat at the hottest spot of the phone during charging? I think qc3 has the same charge rate but its able to change voltage to reduce creating waste heat compared to qc2.0.
my main concern with the s7 is the battery life, i know it won't last me a full 18hr day so i really need a portable fast qc2 charger that is pocketable, so maybe 5000mah, but have not seen such a small qc charger tho

I don't have a thermal camera, or way to do that otherwise I gladly would. I can recommend a small 6000mah external battery pack if you want; Ill do a quick write up too (if you need one). The Samsung charger stayed at 9V the whole time per my multimeter's reading it just dropped go .5A near the end.

Thank you, I will add in a standard wireless charger test (since my free Samsung one is enroute), and I can also get their fast charger too. I believe Samsung's fast wireless charger is only 7W so it would be slower than the Choetech one but it never hurts to see how fast it is.

@Pilz yes pls let me know of a qc2.0 small portable charger I think a quick 30mins charge to add 50% battery life mid day will be the best ease-of-use solution for me.
with the heat measurement, I'll be happy with your commercial grade temperature sensor that the great designer created for you, your fingers or better yet, the inside of your wrist.
preferably touching the same area on the phone every time and grading something like 1-5 hot/comfort levels maybe? just suggesting, no pressure

I'll look into some methods to measure the heat easily while they're charging. I'm conducting the standard wireless charger test using my free Samsung wireless charger right now QC 2.0 chargers the fastest when you start at a very low battery percentage, so ideally you can achieve the results posted, but ambient temperature, starting % etc contribute to whether or not that's attainable. It's still a good estimate for 30 minutes of charging +/- 5% for other factors. The phone also chargers slower when the screen is in. The rate would go from 9V/1.67A to 9V/1.10A with the screen on. It was very consistent when I turned the screen on and off during the test.

i actually won't care about heat issues while charging this time round, it'll be like my moto defy, i just run it under cold water after a fast hot charge, wont be using the s7 for many years so not worried about moisture build up.
i have ordered a magnet micro usb cable that says its rated for 2.4A charging so hopefully it'll allow easy qc2.0 charging, no need to plug in, it magnetically snaps on and off.
i think the best charge setup would be a 30mins quick charge (magnet) on the office desk than a 60mins wireless qi charge, carried in your pocket type situation.

Did you by chance order the Znaps? I backed them ages ago for both the Type-C and micro USB connectors. If I'm lucky I might eventually maybe sometime before I die receive them. I don't expect much from a kickstarter campaign that's been delayed this much. I'm finishing up the standard Qi/PMA charging test. It shouldn't matter the standard it's using but if it's important the Samsung wireless charger is actually PMA.

OP Updated
-Standard wireless charging test added
-All figures updated to reflect the new test

no, its from aliexpress, $10 or so, ive seen cheaper so I would say the poor Kickstarters had their designs stolen and made cheaper... im not sure, i just buy what's available and easy. just search magnet usb cable, you'll find heaps, the more exy ones claim 2.4A current rating.

Let me know how it works, I rarely use cables to charge my phone becusse I hate micro USB ports plus I'm used to the type C on Nexus.

Have you tried charging with 18w charger(not wireless) rather than the samsung one?

Yes it doesn't matter becuase the phone is only rated for 15.03W so it can't use more than that no matter the charging method. See screenshot below:

@Pilz yeah sure, it should arrive in a couple of weeks. i hate plugging in as well, even with the usb type c, its reversible but finding the port isn't always easy, they should have made the port surface like a cone or funnel so your guided into the port more easily.
the use of the magnet is awesome, Sony's external side charging pins have been around for ages, its really the charging current and quality of the copper that im worried about.

I just wish they had Type-C because its so much better especially after using it for a while now.

I never knew that plugging in a micro USB cable was so difficult. It could be one of those things that once you try a better alternative (type c maybe?) makes you ask how you lived without it, but I don't see what the fuss is about just yet.
I've used wireless chargers for years (way back in the NExus 5 days even) including in the car. Any word on fast wireless charging and heat? I'm worried about it pumping a ton of heat on to the back of the phone especially for extended periods such as overnight.

Micro USB is just more of a hassle becusse usually you need to angle it while inserting it into the phone. Type-C is nice becuase there no worrying about how I need to orient a cable when I'm half awake plugging my phone in. It's hard to understand why its nice until you use it everyday.
I haven't been able to measure the heat yet, but the phone is cooler using the 10W wireless fast charger than it is using QC 2.0. The phone isn't hot to the touch but it is warm using the fast wireless charger. I'll try to download a battery monitoring app that measures battery temp while it's charging. This method won't be as accurate as physically measuring it, but it should still give a good indication of the temperature.
Edit: I tested the temperature using GSAM battery montior via the fast wireless charger fro ~6% charge (28-34%) and the temperature rose 6 [F], the I let the phone cool and tested QC 2.0. The phone was charger for 6% to keep things cosnistent with a temperature change of 5[F]. I would need to find a way to more accurately measure these values because that quick test doesn't really mean anything at this point.

Does the Adaptive Fast charging by Samsung with with QC 2.0 compatible devices or is it only exclusive to Samsung?

It's just a QC 2.0 charger from what I can tell. I have a battery pack that will charge using QC 2.0 so I can test it using my multimeter
