Amazon Fire Tablet Not Charging? Here’s How To Fix It
If you’ve used an Amazon Fire tablet, then you know that these little tablets are terrific budget entries in the tablet wars. They are especially great for kids, not only because they are sturdy and inexpensive, but also because the curated app library that Amazon maintains keeps out a lot of the more problematic material for young people. Kindle Fires also make great “Kindle-plus” devices for heavy readers – all the functionality of the old Kindle plus the ability to do tablet stuff when you want that as well.
Unfortunately, many models of the Kindle Fire have a consistent and persistent design problem that Amazon seems to have had difficulty in shaking. Specifically, the Fires have a tendency for their chargers to go bad in one way or another, so that the devices (while perfectly functional) have a hard time taking a charge. Tablets that won’t charge are truly aggravating; the Fire, like all tablets, depends on battery power to run and if the battery won’t charge then you won’t be getting a lot of use out of your device. Fortunately, there are several troubleshooting approaches you can take to figuring out the source of your charging problems, and in this brief tutorial I’m going to show you how to do it. I will also discuss some precautions to take to avoid developing “charger port rot”, the underlying cause of many of these charging problems. I’ll show you some MacGyver-style fixes that can resolve some charger port problems. Finally, I’ll provide some guides to full-fledged repair of charger-related components on your Fire.
(Is your Fire charging OK, but for some reason won’t power up? Check out this guide to what to do if your Fire won’t turn on.)
Diagnosing the Problem

When a tablet won’t charge, there are four possible sources of the problem. First, there can be a configuration/software problem. Second, there can be a problem with the battery itself. Third, there can be problems with the charging adapter or the cable. Last but in the case of the Fire far from least, there might be a problem with the charging port on the tablet. We’ll look at each of these possibilities in turn.
If your Fire won’t charge for some reason, there are some logical troubleshooting steps we can take to find out the cause and then do something about it. We’ll start with the easiest things to check (and fix) and then move up from there.
Test the outlet
Make sure you have power in the outlet you’re trying to charge from. Seems rather obvious, but sometimes it’s the obvious things that get us.
Test the charging adapter
If the charging adapter (the little square that plugs into the wall) isn’t working, it’s super easy to figure out the problem. Instead of using the charger, use the cable to connect to a computer or other USB power source and see if your Fire will charge from that. If it will, then the problem was the charger. It’s important to note that not all chargers are created equal; they have different amperages and sometimes even different voltages. Most Kindle Fires expect 5 volts at 1.8 amps; if the charging adapter provides less than this, your Fire may charge slowly or not at all. The same can be true if you are connecting the USB cable directly to a computer or other USB charging port; those ports can deliver anything from 0.5 amps and up. If the charging adapter is the problem, new official ones are relatively inexpensive and easily acquired directly from Amazon.
Test the cable
The charger is only half of the hardware equation – there’s also a USB cable that connects the charger to your Fire. Above, we tested the charger. Next we need to test the USB cable itself. Fortunately all micro-USB cables are basically the same, so borrow another one from a different device (your smartphone, most likely) or from a friend, and see if swapping out cables will get your Fire to charge. If it does, then you know the problem was your cable – replace it. These are again easily acquired from Amazon.
Test the charging port
Many models of the Fire are notorious for having a weak charging port. Prolonged connection and reconnection can cause the circuitry inside the Fire where the port connects to the battery cable inside to become loose or detach completely. This is particularly a problem for those of us who use our Fires while they’re charging; the charging port was apparently not designed for the stress of having the cable yanked around because someone was holding the tablet while charging it. When you connect the charging cable, make sure the cable is seated securely. If it seems secure, try to gently move the cable while in the socket. If it moves around, it may be loose.
Lay the Fire down flat and insert the charger. This can cause the wires inside to connect again and allow the device to charge. While not ideal, it keeps it working for now, and if this works where other charging attempts have failed, then you know the problem is with the port itself. While not for the faint hearted, this guide shows you how to check the connections within the Fire. I would suggest only trying this if your Fire is out of warranty and you are confident in what you are doing. Otherwise, you’ll either have to baby the connection when you charge it, or replace the whole unit.
Reset the Fire
If all your hardware seems to be in order, you may have a software issue. A full reset will wipe the slate clean and hopefully allow it to charge.
- Hold down the power button for 20 seconds to make sure the Fire is powered off.
- Turn the Fire on with the power button.
All you’re doing here is forcing the Fire to turn off and then turning it on again. This will force close any apps that may be getting in the way of charging and reset voltage within the device.
Factory reset the Fire
The factory reset should only really be performed if all of the previous methods have failed. It will wipe everything you have loaded onto your tablet and return it to its default configuration. There is no guarantee that it will fix the not charging issue either but it has apparently worked for some users.
- Save all your data if you can get your Fire working.
- Swipe down on the home screen to access the menu.
- Select Settings and Device Options.
- Select Reset to Factory Defaults.
- Select Reset to confirm factory reset.
As mentioned, this will wipe your device clean and delete everything. Once complete, you should force a reload of the system software to make sure you are running the latest version.
- Press the volume up button and power button for 40 seconds.
- Release the power button but continue holding volume up until you see ‘Installing the latest software’ on the screen.
- Allow the update to install and reboot your Fire.

He’s still dead, Jim
If you’ve tried all these steps – swapping out outlet, charger, and cable, checking the port and the internal connections, and doing a complete reset of your tablet…then unfortunately the news is very bad. Your battery is likely the source of the problem. Although Amazon does not encourage it, it is in fact possible to replace the battery on your Fire. However, replacement batteries cost nearly as much as a new Kindle Fire in the first place, so you probably should just consider getting a new one. However, later on in this article I will walk you through the process of replacing your battery if that is the route you decide to follow.
Preventing Charger Port Rot
The charging port in the Kindle Fire does not, of course, literally rot. However, with the Fire, as with some other brands of budget tablets, the build quality of the charging port is not always the highest. In addition, most tablets (including the Fire) use the MicroUSB charging/data cable system, and while the standardization of these cables has been extremely convenient for everyone, it comes at a cost. The MicroUSB design relies on many small wires being soldered to a circuit board, and this design is very vulnerable to physical stress. Solder is designed to hold a wire to a component, and although soldering does provide some mechanical strength to the connection, that’s not what it’s meant to do. But we tend to think of our ports as being like wall plugs – able to hold some weight and resist some force. The combination of these factors is that charging ports tend to be the most fragile part of a device, other than the glass itself.
This doesn’t cause a problem for light users of their tablets; people who turn the machine on once a week to watch a movie and then put it away again rarely experience “port rot”. Rather, it is those of us who use our tablets constantly, so that the charging port is almost always in use, who find themselves with a Fire that won’t charge. Each insertion and removal of the charging cable puts a little bit of mechanical stress on the glue or solder holding the port on the circuit board inside the machine, and over time the connection can fail and the port becomes loose.
There are a few things you can do to delay or even prevent the onset of port rot, even if you use your Kindle Fire a lot.
Keep the port clean
Lint, dust, and debris can clog up a charging port and cause it to stop working well. You can use a sewing needle to gently remove dust or debris from the port. You can also use a can of compressed air to occasionally blow out any debris in the port.
Don’t charge and play
When you are using the Fire, don’t charge it. When you’re charging it, don’t use it. The motions of normal use put some stress on the cable/port combination, and what’s worse, when we use our tablets while they are charging we tend to do things like use the cable as a mechanical support for the device. (I’ve caught a dropped Fire by the cable more than once.) This puts all kinds of mechanical stress on the connectors. So use your Fire untethered; if the charge gets low, turn it off and plug it in and go do something else.
Use quality cables
All MicroUSB charging cables use the same basic design, but there are differences between cables. Specifically, very cheap, low-quality cables may be sloppily sized so that while they will make a connection, they are also stretching out the receptor port or bending pins inside it. Use high-quality, well-engineered cables. You don’t need to go spend $30 on a “premium” cable, but avoid the dollar store or bargain bin cables.
OK, it’s time to get serious! You’ve figured out that the problem is in the port itself (it usually is) and you want to know: can this be fixed, or am I on the hook for a new Kindle Fire? The good news – much of the time, you can jury-rig a way to get your Fire to charge, or even completely fix the problem. So let’s get our MacGyver on.
Sounds silly, but in fact a strong rubber band can often preserve the charging life of your Kindle Fire for weeks or even months. You may notice that when you put the charging cable in, the Fire starts to charge but the charge is very slow, or it stops charging once you let go of the cable. This is because the port is just a little bit loose, and if you are putting some pressure on the cable to press it into the port, there is a good connection. Now, you probably can’t stand there holding the cable in place for a couple of hours to give your Fire a charge, but you CAN take a rubber band, loop it around the base of the cable end, and then loop it over the whole body of your Fire. Now the cable is being held into the port by the rubber band, and the connection stays strong enough to get a good charge.
However, be aware that by doing so you are putting more stress on the connector; you’re pushing something in that already has been pushed in. Eventually the port is going to come completely loose and break.
Don’t try this one on your brand-new charging cable, but if you have a cable that otherwise works but just won’t connect with your Fire, the problem may be that either the cable end or the charging port has gotten stretched in one dimension or the other through repeated use. You can apply the pliers very, very gently to the cable end and thicken it in one dimension or the other by very gently squeezing. (I.E., to make the cable end wider, squeeze it gently along the top and bottom, while to make it fatter, squeeze it gently along the sides.) By doing this, you may improve the fit and cause the cable to match back up with the port and work again.
Sewing Needle and/or Compressed Air
As mentioned above, if the problem is dirt in the port, then you can use a sewing needle or compressed air to carefully blow the debris and dust out of the port and get it nice and clean again. Be very careful (particularly with the needle) as you do not want to scratch up the contacts in the port.
You’ve heard of the tin foil hat brigade, but how about the tin foil charger? This should be considered an act of last resort, because in general adding more metal to a charging situation is not the optimum approach, but if worst comes to worst, try wrapping a small strip of aluminum foil around the charging end of the cable before inserting it into the port. The conductive aluminum will carry the electrons between the cable and the charging port even if the connection is otherwise poor. It might work, or it might not. It’s important not to let the Fire overcharge if you take this approach; by using the foil, you are going to be confusing the circuitry of the port and it may not stop charging even when the battery is full. So keep an eye on it.
This is the true last resort; if everything else fails, and you are a good hand with small electronics, and your Kindle Fire is just a brick if you can’t get it charging, you can always try opening it up and installing a new charging port on the motherboard. New ports aren’t expensive (here’s one sample Kindle port) but this is not a job for a first-timer with a soldering iron. The exact steps to follow are outside the scope of this article, but you can find guidance in other places on how to at least try to fix your Fire this way.
You’ve tried everything, even Maximum MacGyvering, and it’s definitive: your battery is dead, and it’s NOT the charging port’s fault this time. The rest of your Kindle Fire is fine, however. This leaves you with two choices: the path of prudence and reason, which is to send it back to Amazon and trade it in on a new one. Or, the path of reckless aggression, in which you jam a new battery into your Fire the way our cave-person ancestors would have done it. Send it back, ha! Are we peasants, beholden to Amazon for every good thing? Well, yes, probably, but we can still replace a battery if we have to. Here’s how to do it.
Getting a new battery
The first thing you’ll need is a new battery. Perhaps unsurprisingly, Amazon doesn’t seem to sell “official” replacement batteries over the counter. Basically, they don’t want you prying their shiny hardware open and sticking your fingers in it, getting a shock, and then suing them for a kajillion dollars, so they don’t go out of their way to make this process any easier. Fortunately, a generation of do-it-yourselfers doesn’t care what Amazon wants, and has worked out a whole system for battery replacement.
However, there are Kindle Fire replacement batteries on sale on Amazon, and in other places online as well; here’s one example. They aren’t from Amazon, they’re from third party battery manufacturers. You’ll need to know the part number of the battery you are using; you can find that information online in your Kindle Fire specs before you’ve opened up the case, or printed on the battery itself after you’ve opened it up. As it happens, opening up a Kindle Fire and removing/replacing the battery is relatively straightforward.
It’s not rocket surgery
Warning: if it is not completely obvious, opening your Kindle Fire up in this way voids your warranty so hard that Jeff Bezos may well come to your house and throw eggs at your door. You have been warned. That said, this isn’t particularly difficult to do. Just take your time and start out with the minimum force, and only slowly use more force as needed.
You will need one tool: commonly called an “opener tool” or a prying tool, sometimes referred to as a spudger for the tougher spots, this tool is basically a strong but flexible plastic or metal curved bit that can be used to gently pry open the glued-together electronics of a smartphone or a tablet. There are a lot of varieties out there; you can even use a screwdriver if you don’t mind all your panels being scratched up and bent. One excellent all-purpose opener is available (of course) on Amazon but you can use any tool you like. I personally like this multi-tool kit which has a wide variety of openers, giving you the ability to work on all kinds of small electronics. The key thing about your opening tool is just that it needs to be strong and thin.
Step One: Remove the Back Case
Starting at the lower-right corner of your Fire, work the opening tool into the crack between the front and back halves of your case. Gently pry the case open; use a penny or some other small object to hold the case open during the next steps. Run the opening tool around the case, releasing each of the clips that hold the case together as you go. You will need to gently pry the case apart to be able to reach all the clips; use additional coins to hold open each section of the case to avoid over-separation while there are still clips in place, which can cause the plastic internal components of the case to snap. Once all the clips have been released, you can pull the back of the Fire right off.
Step Two: Free the Battery
Use your opening tool to work along the right side of the battery, breaking the glue that holds it into the frame. Work all the way down the right side, then repeat the process on the left side. Fit the tip of the plastic opening tool between the right battery cell and the Kindle Fire’s frame. When all the glue is loose, the battery should be freely movable. Gently lift it out slightly, then use the opening tool to push the battery connector out of the socket. The battery is now free of the Fire and you can put it aside.
Step Three: Replace the Battery
Place your new battery into the Kindle Fire and connect it to the motherboard. You may reglue the battery into the case if you wish; to me, that’s overkill and some two-sided electrical tape (some comes in the kit mentioned above, or you can get it cheap on Amazon) will hold the battery in place just fine. The back of the case will snap right back on, just gently apply pressure around the perimeter and each clip should snap back into place (if you didn’t break them in the opening process).
That’s all it takes! And now your Kindle Fire is as good as new. Just look out for Jeff Bezos holding a bag of eggs.
