Observation: Overheating AC Adapters

I like many people was having issues where the AC adapter would randomly stop charging my tablet. Someones it would start working again soon after and sometimes almost an entire day would go by before it started working again.
Tried the freezer trick with no results. Was going to send it back to Asus when I noticed 2 things.
1. The adapter was very not every time it stopped charging.. hotter than it usually gets when functioning correctly.
2. It only ever stops charging when i'm using a usb 3.0 extension cable.
To test this i stopped using the extension able for about 2 weeks and the adapter functioned properly the entire time. Then last night I reconnected the extension cable and within 5 minutes of of being plugged in charging stopped and the adapter was extremely hot. This obviously leads me to believe that the extension cable is in some way effecting the adapters voltage or something and causing it to malfunction. So I'm curious as to how many of the others who having issues are also using extension cables.

Not the voltage the current the more current it has to push the hotter its going to get and the chargers for these are not designed for extensions they where designed to be small and charge the tf even then there at there limit

I also was having trouble with over heating and have been using an 3.0 extension cable. I will stop using it and report back.

its a design flaw with the ac addapters and its one of the reasons that the cable that ships with the transformer is so short

I was just using the cable as is with no extension and it died on my twice. I now have it rigged up to charge from my PC's PSU and only use the adapter when I'm not at my house.

My charger melted my damn usb cable. Thats how hot it got..
I wasnt using the extension cable at the time.
The adaptor would always warm up, which i read was normal. A few days ago, however, i felt some heat on the cable itself.When i reached to the connector, i noticed it had literally melted the rubber casing off the wire.
Im in the process of sending it back today

Just had my second charger die on me! I was charging my Dock and Tablet during class from 2:50-4:10 and when I unplugged it the charger was pretty hot. I went back home and connected the TF to my rigged up PSU charger and then went to class at 6:10 and plugged in the charger and unsurprisingly it wouldn't charge!

Ive heard reports of people solving these problems by swapping round the mains pins ( I guess only in countries that use 2 pin outlets, UK have 3 )

I am sure this will sound nuts but, put the wall charger in a plastic bag and put it in the freezer for a few hours. Please do not forget the plastic bag. There is a thermal heat fuse inside the brick that needs to be reset. If it is still working the cold will make it reconnect and bring the brick back to working order.
You should make a DIY charger by following "DevCake" thread on DIY AC and DC chargers for the TF.
Hope this helps.

I just do not understand why we would have to go out of our way for their crappy idea of a charger. I understand the idea of not allowing aftermarket chargers because they want the money for the chargers but i mean if you do that then at least make something worth having besides giving us a heater...does this remind anyone of the rrod( red ring of death) for the xbox... to much of a hurry to send out their product they didnt really test EVERY aspect of their device...this makes me sad..and then need to send it back and what not taking up more of our time then not being able to use the tablet because your chargers going back... i wish customer service was better....that is all

just a quick pop here.
but i have found that if you charge the dock and tab separately there are no problems with the adapter. and besides charging while the tab is docked into the keyboard is kinda a waste as its charging the keyboard dock, and at the same time its discharging and trying to charge the tab at the same time. hence causing the strain on the adapter.
besides charging both at once will just kill the keyboard dock in the long run

Mine doesn't speed charge my Transformer even without the extension cable. Maybe I'll do some testing with that though and check the heat, since the damn thing doesn't work anymore anyways. Though I might not get any results because of that

There are many problems with the charger, many different problems.
I barely use my dock, so I have only been charging my TF standalone. Still stopped working though late last week.

Hmmm, issues here as well...
Charger stopped working at times and then start working again... Now it's not working and sticks with that plan. Pluggin in the charger with the TF turned off makes it boot so something IS happening, it doesn't charge though.
Luckily I have another charger (no original asus but using another adapter + usb-cablethingie) so I can atleast charge it, but still. Was thinking of buying another asus adapter (the travelpack) but really doubting it now if it's a general issue.
Will try the freezer trick anyway and some other stuff... Quite annoying though (for an otherwise excellent product).

i thought the accessories that comes with the TF are all covered under a one year warranty?
and the problem with the adapters suddenly dying is probably the capacitors in the charger or the stepdown transformer in it anyone had a chance to open one yet?

An Asus UK tech support guy actually told me not to charge both the tablet and dock at the same time. Pretty poor if you ask me. They just went silent when I pushed the matter.
They have compromised the design in their desire to make a fashionably tiny charger.

Actually it is charging, but not with the voltage it requires for the "quick charge". Mine does the same thing. If you turn off the screen or turn off the TF and leave it plugged in, it charges at ~3%/hour. Not very useful if you're a heavy user but better than nothing until you get a new charger.

I may be really lucky: the only time I've ever had a failure to charge, has been fixed by taking off the plug and snapping it back.

Oh yeah me too
I'm going to get another charger tomorrow when I go pick up a joystick for Battlefield 3
Then I'll contact Asus I guess and get it RMA'ed. Going to try and get some free shipping out of them. Sometimes I am successful sometimes not haha

grrrr - Transformer stopped charging!

My Transformer stopped charging last night - think my power adapter has borked! I do so wish they had used a standard charger as I have loads that should work but don't because of it. Oh welll - it's under 6 months old and UK law is pretty good so back to the shop later to make them replace it. I'll have to argue though as they'll refuse to start with.
Got it trickle charging for today to see if it's up and running for later.
I do really wish that people could make stuff that lasted. OH's iPad has lasted for 2 years (ish) with no issues at all. Both my Android pads have failed within 6 months (though one was an Archos and the build quality was dire).
Cross fingers for me...
Well thanks to you all that suggested the freezer fix. Worked perfectly.
For all those in history that stumble on this post - what I did was put it in a zip lock bag and in the freezer for 15 mins. All worked fine after that.

I nerver had any charging or charger issue since my first phone, that means about 2 years.
Did you tried another with another charger ? I mean try your usb wire on an other charger

Other chargers won't work as they don't put out enough power. I am seeing if the cable is the issue by attempting a trickle charge. If that doesn't work then the TF itself is at fault.
I've not had many issues with stuff at all. Just the two android tablets I've had. Suppose I could just be unlucky.

I don't know if it's luck. Although we all want low prices I think cost savings by the manufacturers have gotten to the point where quality has suffered. I've never had any problems with electronics but I'm on my THIRD rma with my Transformer, the powerswitch broke, the dock was draining the tablet, and now after ICS it's not working at all. I would gladly have paid more for a higher build quality. It may be a coincidence, but no more Asus for me.

Put the charger in the freezer for 15 minutes.
Worked for me

If it turns out that the charger is bad, rather than replace it with another poorly designed charger, get a Dynex.DX-UA universal charger. Then you will have both AC and Dc charging capability.

Worked for me too.... Thanks.

Try to play w/ internal connections on the charger. Mine was jacked up and never charged half the time so I slid the wall plug off of it and bent the wires so they pressed a little harder against the inside and haven't had issues in 6 months.

Unfortunately this is a common issue. I have 3 tf 101s and one of them came with a borked charger. All those tricks work butthe issue will almost be guaranteed to return. Just go but a charger from radio shack or something... They make a 12v charger that has interchangeable connectors, including USB. Works like a charm... Sets you back about 20 bucks but well worth it.
Asus build quality does have some issues, I nor anyone I know personally have ever had problems aside from the chargers. But you hear of plenty of issues here... Honestly most are user generated issues with bad flashes and inproper use, but there are legitimate issue as well. Dock drain is the most notorious that comes to mind, but even a lot of those were because people had the no sleep while charging setting enabled.

Try charging over night and then go into recovery and wipe battery stats and reboot. That may fix your issue.

I didn't root my tablet. I bought this tablet 7 days ago and i was never able to get it past 80%. I have tried turning it off and then charging and that didn't work either.

Same thing happened to me. None of the recommendations worked. I ended up purchasing another (official) charger from Office Depot for about $29. I needed to buy another one anyway. The broken adapter is on its way to ASUS via RMA. Note: the shipping may take 2-3 weeks. I didn't like that since I use my transformer a lot when I travel for business.

Putting in the freezer worked for me. The real question is how long will it last and why did it stop working in the first place? Going to call Asus to see if they'll send me a replacement.

I have the same problem now. You should try this to charge it:
1) have the tablet turned on
2) connect power supply like you ordinarily would to charge
3) turn of the tablet by the power button
4) profit?
If you can't get it to turn on
1)plug in your cable to charge
2) if it boots do the above steps if not hold down the power button till it shuts off and quickly hold down the power and volume up button(apex mode) and let it charge
I'm shipping my tablet back for repairs at the end of the month.

I had the same issue, and the following solution worked for me (fixed my charger in under 3 minutes!). Basically you use a small screwdriver and bend two contacts inside the USB port on your charger a little bit.

My Xoom learned a new trick...

...Play dead.
We all know how brilliant a design the charge cord adapter is, I myself am on to my third one in almost two years. Well, the tablet stopped charging today and no matter which wall outlet I used or how much I wiggled the lead I could not make the light come on. Seeing that my Verizon contract is all but done at the end of this month and rather than buy another charge cord I decided to buy a new tab. I just picked up the new Asus Transformer Infinity, not too bad so far. Anyways, about 20 minutes after getting home with neither tablet charged to a useable level, the power goes out for a couple hours- just my luck too. When the power came back on suddenly the light on the Xoom came on. I hadn't touched it since I gave up on trying to get it to charge. Now here I am with two tablets and a $500 hole in my pocket. I know I was bound to get a new one eventually so I'm going to hang on to it but I never saw it happening like this.
Has anyone else had any issues regarding their chargers? Or anything unusual occur in general? I'm sure I'm not alone.

Ouch I would hate to folk out another $500 dollars for a new tablet even though my old one still works. I don't use my tablet for any intensive apps like games, so a new one would be pretty pointless for me. I never had any issues with my charger, well one time one of my charger did blow up, but that's because the battery was faulty for my jump charger for my car. Other than that, you might have some dust in the charger pin hole? Just a guess really.

I'm on my third charger since March. Original Motorola one died, second one (off eBay) burnt out, current one (off eBay) still working but I can't use the touchscreen while unit is charging.
I live remote using an off-grid power supply so this may have something to do with it.

Huh. I have four of them, from the original back in Feb '11 to one I was given a few months back, and they all work perfectly- and most of 'em are used every week (two at home, one in the office, one for travel).

agreed with kcrudup, ive been through 2, the only reason being i snapped the connector on the first one when i pulled it out at a bad angle

The charger that came with my refurbished Xoom lasted almost through the first charge. I thought I was going to have to send the whole thing back until I took it into the Verizon store and verified that it charged with a different charger. I've since got one off eBay and another with the standard dock. Both have been holding out so far.
Oh and my Xoom touch screen doesn't respond while charging either. Somewhere I read that a factory reset will fix that... but I'm waiting until my 90 day warantee is up to put EOS on it since my BT mouse works while it is charging.

My original charger is still working and I got my tablet 8 months back. I think the charger has lasted pretty well. How long did peoples original ones seem to last?

That's an electrical problem (noise and/or grounding issues with the charger raise the "noise floor" so the touchscreen controller has trouble determining what's a valid touch) and can't be cured by any reset, factory or full or ...
Your issue is your charger- try another.

Just a quick note.. I've had the ebay sourced chargers fail on my xoom ( and other devices). I found that the power ratings on some of them are rather optimistic... they simply are running at the outer limits to charge the tablet and failure can be internal to the power unit...best case.. or worst case failure dumps overvoltage or raw AC power to the tablet.
Fortunately my failed units were of the internal power supply version.. and aside from bad smells no real damage was done.
I have successfully built charger/power units after scavenging the connector from my failed power supplies and using a minimum 1.5 amp 12v dc supply... they seem to work fine.. and keeping one handy is much more convenient than wondering where I last used it :fingers-crossed:
as always.. your mileage may vary

Hmm, that's interesting. Unfortunately this charger is from Verizon and i would surely hope that their stuff work to the correct specs. I wonder sometimes that maybe the problem could be with the contact inside the tablet. Could that have something to so with it?

I think the Motorola/Verizon chargrs are good. I think the earthing issue is with the cheap chargers from China.

When I lost my cellphone charger I had to buy a Chinese one, well, when charging it looked like possessed by the Devil itself lol! The screen started acting strange and I wasn't able to control it... Then I found my original charger and the exorcism was complete lol^2! BTW, a guy on X10 mini pro community (one of the best developers I ever met - my favorite one ) lost a cellphone with a Chinese charger, so what can I say - be careful with it!

Unable to charge!

I just starting having this issue last night...out of nowhere while the phone was plugged in, it said "Unable to charge. Use the original charger."
The odd thing is it actually charges a little in between the messages popping up, so it makes no sense...it's an obvious contradiction. lol I did a reboot but that didn't fix it. I'm using the oem charger.
This morning it happened a few more times but after unplugging and plugging back in quite a few times, it seems to have stopped - it appears to be charging normally (for now), but I'm still concerned!
Any suggestions/ideas?

I've seen it happen now and then on my phone. Usually it just means the charger isn't very well suited. This happened when I was using the charger for an MSI Tablet that my wife uses and keeps plugged in in the living room. It does charge very very slowly.
On another note, I actually had the phone tell me last night while I was outside that the battery was too cold and that it couldn't charge while hooked up to my external battery pack.....now THAT was funny.

Were you using the original charger the whole time? If so your USB port might be going bad?? I had to replace mine on my Galaxy Nexus which was a Samsung.

True, that would be odd. I got mine just a week or so ago and it charges fine with the original 3.0 charger and my old 2.0 ones from my galaxy nexus. I'd just keep an eye on it and if it keeps happening, it may be worth getting a warranty replacement.

Hey man, it's funny that you say that because if it continued to not work that was the next thing I was gonna try (standard usb cable) thanks for letting me know I'm not alone here!

If it continues to happen I'll be trying for the warranty exchange as well!

I'm having a severe case of this issue on my Note3.
No matter what charger cable I use (including 3.0 OEM), w an OEM base or not, no cable will charge and always gives me the "Use original charger" statement. The only way to currentlly power my device is via Qi Wireless or swap batteries.
I'm not sure what may have caused this.
The only big difference with my usage is I recently bought Anker batteries for swapping the OEM battery. But I've put my OEM back in and Im still getting this issue.
Dont kno if there's any relation but LG Qi Pad use to charge through the Seidio Dilex just fine, but now I have to take the case off. Qi Wireless charging still works fine on my Lugulake with the Dilex on though. Difference between then and now is I added a Skinomi on my back cover (excessive, i kno, for those occasional days when I want to go bare).
EDIT
my PC doesnt seem to detect my NOTE3 as a storage drive either when plugged in. Ugh, i may have a busted port. I wonder if I may have damaged it when installing my Skinomi. The adhesive requires heat to activate so I had plastic wrapped my phone and wrapped a hot towel around it to help thhe curves stick down (no it wasnt plugged in at the time)
other details, likely irrelevant, is I recently added a 64GB SDXC the device that previously didnt have external Storage.

I have this issue with my Note 3 as well it will charge with 2.0 but I get error message with 3.0 I called verizon first time after saying they would replace it they sent a 12" usb 2.0 cable which they charged $20 for I called back second rep stated she knew what i meant and she would sent the correct one out right away and of course remove the charge The sent a 3' usb cable with a led on it so i call back a third time and was advised they do not have usb 3.0 in stock and internal documents instruct them to transfer to Samgsung I call samsung and they rep tells me nope we don't have usb 3.0 either and that their documentation advises that they ship usb 2.0 I know this may seem petty but I paid $600 for this phone and I want to use usb 3.0 and it should be functioning oh yeah charging phone with cable with usb 2.0 that i had from my note 2 and now I see never carrier or manufacturer really care since they have my money and 2yr commitment

charging too slow , use original charger
I had this problem for some time now
it used to happen once every few weeks
now the phone doesnt charge using the original usb 3.0 cable provided with the device
I have no idea whats the problem
I plug it in and yet battery still goes down
leave it for hours and its not fully charged
and keels disconnecting
tried another cable, still the same problem
am out of the states and so, no verizon tech support

The TN7 has unfortunately been known to have wonky USB ports, so if you're having issues with it then you might want to contact the manufacturer and see about getting a replacement.

I had the same problem and I was able to fix it. Turn off the device, take a needle and try to narrow the USB port, GENTLY AND SLOWLY, try to make the hole to be tighter. I hope it helps. Tegra note is ****y stuff...

How?

Hey there my usb port, like many others has also gone bust. You mentioned trying to narrow the usb port, what do you mean by this? My tab has be useless for the past month since curries refused to repair it saying it was my fault. I guess its all down to me somehow fixing it any help would be appreciated. Thanks

Have you tried holding down the power button for around 30secs. My battery got drained completely and it didn't seem to be charging, even after a few hours using different chargers. After holding down the power button down for 30 seconds. Then releasing the button. Then pressing again. It came alive.
I may have had a different problem but hope it works for you.

charging problems...the port maybe?
Just bought a refurbished evga tn7 from ebay and it was charged 84% so cool. I played on it for a while bout maybe an hour or so. I left it to charge that night and it didn't charge very fast. Ever since it will only charge with the wall outlet with another cable or the one that came with it. Takes about 6 hours or so to charge even 40%. It also discharges very quickly about a percent a minute or so. It came with the 4.4.2 update. I love this tablet but I can hardly use it because of this. Please help!

hya - its not hard but you need some nerve, it is relatively easy to wire a QI wireless receiver direct to the battery then fit a charger into a suitable case.
I've done four of these now using fintie slate 7 extreme cases (ebay US) and QI elements from ebay UK. cost about 25 quid or so.
short term or as an alternative you can strip a usb cable or get a micro usb extension cable and wire that to the battery instead so you can charge it up using a smart USB charger. it is possible to wire into the charging circuit so it registers if you are carefull and solder to the board side of the USB otherwise the QI is probably a better option as the charger will switch off when it decides the battery has been charged minimising any possible fire risk from overcharging,
it is also possible to get a phone/computer repair shop to fit a new usb socket as the boards aren't available for some daft reason - they are listed on alibaba but not available.
the only issue is not having a working usb port but as long as you don't want to root the device it doesn't seem to be needed.

my wireless mod charges slower than it should as its only rated to 1A but not that slow - Ideally you need a 2A charger for tablets min 1A for decent charging, most phone chargers are 500-750mA.
otherwise turn the tablet off and all the power goes to charging.
