Same here. I am afraid to leave it plugged in for too long. I am sure my fear is unfounded but it get hot enough to make me nervous.

When the tablet is 100% charged, it doesn't get as hot anymore. When nothing is plugged in, its cool as a gem. I wouldn't worry about it. Laptop chargers run about as hot as this.

Side effect of pushing current?
HEAT
Yeah, it will get a little warm, maybe even a bit too warm to hold in your hand for more than a few seconds. If you need to unplug it to stow it or take it along, unplug your TF from it and let it sit for a couple minutes.

Same, the charger feels dodgy to me.
Think we can use an apple charger like this for the Transformer cable?
edit (cant post link but its the apple usb charger that is larger and more rounded versus the tiny box like one for phones).
the apple one says output of 5.1V 2.1A
the asus one says output 5.15V 2.12A (I think, text is ludicrously small)
Loving the device by the way, but yeah the powerpack does not inspire confidence at all.

Someone mentioned in another thread that part of the reason for the charger getting so hot is because some people have been plugging it in the wrong way. The adapter should be plugged in with the "S" in "ASUS" lining up with the wider prong on the outlet

chargers get hot. Plain and simple.
My laptop charger feels like it'll burn straight through the carpet.
The things people complain about... lol

True, but someone's TF charger has already melted see http://forum.xda-developers.com/showpost.php?p=13894929&postcount=15. No charger should get so hot that it melts.

I don't have this problem. The manual shows a diff kind of charger than I got in the box though. I just got my tf today. Manual shows a charger consisting of a power plug piece, another piece which plugs into power piece, and USB cable that plugs into that. I have just a power piece which has a USB port on it, plug in and go. Charging from first time charge on both dock and tablet for 5 hours or so right now, tablet is charged full just dock still charging, adapter is barely warm.
The charge light on my dock is still red though, thought it would have changed to at least orange by now. The tablet has been at 100 for say 2 hours, and removed from dock for about an hour.
Update, it is getting hot after being plugged in for around 6 hours, not so hot that i'm worried. What's more worrisome is that the docks charge light is still red after all that time.

The power plug is already attached to the PSU. Similar to how Apple laptop power bricks allow you to put on a different power plug.

True, and unless yours is melting, it's not too hot.

Anybody actually got a temperature reading?

gonna see if I can charge the thing at work and use our IR temperature reader to get a reading

Using an IR ThermoGun I get 58.1 degrees C or 137 degrees F
Thats after an hour currently charging Tab and dock together

Mine is warm when it is charging but not hot. As soon.as the charging completes it shut down and is ambient temp.

That is indeed what I was agreeing to in my post yes.. I mentioned in a previous post as well that it got hot while actively charging, but not excessively so, and nowhere near the point that something would melt.

My Charger melted

wtf...
tablet wasnt charging. The charger was plugged into the outlet with the usb cable connected.
i noticed my tablet was dead and when i go to charge it, i feel the cable is hot..
then notice rubber/plastic casing that covers the pin connection, is melted.
(the part with ASUS name)
not sure where to see the model number. i just smelled it and its not good... fawk
I wonder if they got the same company as apple to make the proprietry cables lmao
But seriously thats not cool send the pics to asus they will probably send you a new one and a cover or something to keep you happy

Contact ASUS, send them pics. Do Not send them the unit yet. If they don't replace it immediately, send it to UL Labs.
Asus tech support have the tendency to not think at all and just declare your warranty voided because the outside is melted or whatever. They always claim it's a sign you tamper with it.

i have to do so as well
With the history ASUS has with AC power adapters we all need to keep a watchful eye on our adapters. It appears they maybe under built. Meaning the components used in their construction are not big enough to handle the load.
Maybe we need to follow DEVCAKE's thread and build an AC adapter?

By the way my adapter died yesterday.
I've never noticed anything with my TF's charger (I just worry about the cable getting damaged at the docking connector), but now that you metion that...did notice that my Eee PC's charger always did get awefully hot at the brick :-S
So i called yesterday after i got lost in that crap website. most links would end up dead.
The rep gave me an RMA number and emailed me instructions.
I sent them an email with the pic. THanks for the suggestion. Hopefully i can get something resolved.
For now...i cant even charge the damn thing.
I know this is almost a month old since the last post, but curious to know, did they give you any push back or require the old 1 back?
Same here. My Asus charger is very very hot. I need to emphasize the very because its really very hot.
These chargers are very cheap. Running hot is a known issue and if it quits working put it in a ziplock bag and put it in the freezer for 30 minutes. Sounds stupid but it will reset the overload switch in the charger. I've done it. I also don't keep my tab on the charger all the time.

Ever since I got my first asus product, (eee pc 2Gig surf) I have had charger issues. They always make them very flimsy. My transformers charger gets extremely hot as well. My grandpa owns a viewsonic gTab and the charger for that doesn't burst into flames like mine when he charges it. Thanks for the pictures, I won't leave it plugged in when its not charging anymore.

I had to do something like this with my ASUS netbook. It had an indicator light on it that would randomly stop working because it got too hot. Had to unplug it for up to an hour to get it to work again. On that note anyone know of any third party transformer chargers that work better/less hot?

Did you include the socket adapter (UK/usa/europe plugs)? Or just the bare adapter...
Have to send it in as well (getting it picked up tomorrow) and wondering whether or not to include the plugs/adapter.
i love how asus charges $50 for this overheqting piece of **** charger. if they are going to pull an Apple on pricing then the quality better be top notch
Mine died to (I don't really know from what but i'm guessing from overheating or some low quality issue), and I found a perfectly fine 12v output AC adaptater with USB port for 10$ in a supermarket. It's a little heavier but have a much longer cable and doesn't threaten to burn my house during the night.
But loosing the USB cable itself must be anoying.

Fried eee pad?

Well ladies and gents, I think either my eee pad has been sucked dry or the charger fried, or both. I went to turn on my pad and found out that both the dock and tablet were at 0%.
I plugged it in got it booted and after an hour, the orange light on the side of the dock stopped blinking and stayed orange, as if it were charging, but the pad still showed at 0% for both pieces. I unplugged the charger to find it was so hot it was almost untouchable and as soon as I unplugged, the tab shut down. Also the dock was not usable to type while plugged in. Am I screwed with this piece?

Zip lock bag your charger and put it in the freezer.
lol really? put it in the freezer? Hey test the usb cable first by connecting it to the computer and see if you get a response. If so for the most part you have like a 90% chance its not the cable. More then likely the adapter is messed up as stated above. The AC plug itself is detachable, its hard to get off but it comes off. You will see its two pieces one big piece and a slimmer piece. Dont rember witch direction it SLIDES off but it comes off. Just check around it and make sure its not blocked or anything. But yea might have to get a new one.

Really. There is a heat sensor in the charging cube that disengages the link in case of overheat. Zip lock bag is there to keep out moisture.
Crazy. I unplugged the charger, let it sit. Plugged it in 20 mins later and all of a sudden my tablet has 60%. This thing is weird. Gonna have to teat more thoroughly ans possibly get a new charger

Good. Just remember. If this happens again but next time the safety won't just disengage, then throw it in the freezer like I instructed.
Added by edit.
Then of course chances are you won't do this. Most people are not modders because they are too afraid to do anything out of the ordinary. This is why the ipad is so popular. Anyway, if this is your case, then I guess the alternative is to get a new charger.
I just want you to know that i tried Goodintention's advice and it worked for me. That being said, do not wait to get a charger replacement by following DevCake's thread on how to make up your own charger for the TF. Once these chargers start going bad the only way is downhill.
My second charger died yesterday and I am following Devcake's advice.

[Q]Wall Wart Is Hot

Just got my tf101! Question, the wall wart is extremely hot, almost to the point of not being able to hold it. Is this common? This is the first charge.

it cooled down after it was done chrarging. Maybe it was the initial charge, the battery was completely drained.

Wall Wart Gets Hot
It is not the voltage that makes the wall wart get hot but the current. On first charge the batteries are demanding a lot of power [current] to charge up. So the wart gets hot. However every time the batteries get very low on their charge the wart will have to put out a lot of juice to charge the batteries up and so will get hot again. The wall wart is just not beefy enough to really handle a lot of demand from the batteries. You might want to read thru some of the posts on making up another charger for the TF. Any wall wart should never get so hot you can not handle it.
Happy New Year
hshoem1
I got my Transformer back in June this year and the wall wart has almost always heated up to a point where I've thought it to be unnatural (based on how most other device chargers do not get so hot), but it still to this day gets fairly warm every time I charge it and I have not had any issues with it. It seems to be normal behavior for the charger. :/

question about over heating and charging...

Should this phone be able to handle playing music from a downloaded spotify play list and run navigation at the same time through blue tooth without over heating or draining? I had the phone in a windshield dock the air conditioning was running. I noticed the phone was hot to the touch and despite being plugged in to a charger the battery was draining. I'm on the latest clean rom not overclocked.
After taking it down out of the windshield and keeping it right by the AC vent it cooled down but the battery still drained.
ETA: more details and clarified the question
I use panodora and navigation and haven't had an issue. If it's really hot out I aim one of the AC vets at it and that keeps it nice and cool. One of my docks is right below a vent so it works out perfectly.

It gets warm for sure but not hot to the point of overheating. If it's in the sun though that could make it get too hot.
Sent from my HTC One X using xda premium
Probably a dumb question but what's the voltage output on the dock? I had the same problem with my original Evo back in the day using a generic 600mA charging cable. Switched to a higher output and it stopped, although it's still charged SUPER slow while using navigation and music...
Never shut down or anything but maaan that puppy got hot.
Standard usb cable. Not a powered dock.

Ah okay gotcha. Does it plug into a usb port straight through the car then or is it a cigarette lighter? I know this is irrelevant to the heat issue, but that losing battery while plugged in drove me nuts. Turned out the usb cable/plug I had wasn't pulling enough power from the cigarette/accessory outlet in the car to keep a positive charge going under load.
The phone showed it was being charged through "usb" instead of "a/c"
It's a cig lighter usb adapter. Never had a problem like this with any other device but I've never had a phone with this large a screen either.
Does it say it's charging through a/c under Settings->Power? Or usb? I know usb charges much slower. Most wall or car chargers list the output on the plug somewhere.
From what I've seen, anything around one amp should trigger a/c charging mode. Never had a problem with charging no matter what I run then.
I didn't look but the orange light was on and I saw the charging animation. I'll look at it next time I plug it in.
Hope that's at least helpful for the not charging thing anyways. Sorry for the semi-OT.
Anyways, I know mine gets warm when charging and when using navigation and gps. Combine the two and it gets scary. This has happened with my Evo, Evo 3d, and HOX. Dunno.
It worried me enough to post about it.
I just looked at the charger and is says 1000 milliamps max.
So your question is whether the phone will get hot while charging the battery and using navigation? Uh... Yeah, it will do that.

No my question was will running navigation and streaming at the same time cause it to overheat. One of the first things the phone do when it over heats is stop charging.
I had the same heating issue so I changed the charger - now, I use one that outputs 0.7 instead of 1.0. The default charger outputs 1.0.

On my way home from Atlanta I stopped by an AT&T store and explained my problem. I purchased a 30 dollar usb car charger from them. On the way home I made sure it said charging on ac. I used Google navigation and spotify playing cached content and lost 20% in 2 hours. If this phone can't keep up with running 2 things at once I'm going to have to get something else.
would you believe a factory reset fixed it?
WEIRD
On my drive back today I resorted to turning off the screen when GPS was running. It was charging, but very slowly.
So a factory reset improved it for you? I might try that.

Very strange man. So none of the heat issues anymore or anything? Glad you got it sorted out.

Dock won't charge but still charges tablet and functions well.

I've seen many questions about the dock but can't find one that talks about this issue I just had this morning.
Last night both my tablet and dock were charged completely. This afternoon I start using my tablet and notice the tablet is at 30% and the dock is fully discharged at 0%. I plugged the keyboard in connected to the tablet to charge it. The tablet is charging just fine but the keyboard is flashing the orange light and is not charging. I have tried plugging just the keyboard in and it is still flashing orange and not charging. I thought it could be the power supply but the tablet itself is charging just fine.
Does anyone have any ideas I should try before trying to see if I can get a replacement?

When the dock is fully discharged the red led will flash for a while when your charging. It's normal, when you have charged for a while it will be constantly on!

Defective. Exchange dock or send to Asus for repair.
I don't know what happened but I left it plugged in all night yesterday and this morning it was half charged with the light on orange so I'm hoping that sometime when I was sleeping it fixed itself.

I've had a dock die and just flash with no charging on the prime before guess it was defective. Picked up an open box from ebay for 90 bucks works like a charm.
I got the dock to charge, but had to monkey around to get it to fit just right....still not fun....
Got it solved by doing a cold boot.
Turned it off then held power + vol down combo untill I saw the text "cold-coot linux" apear, released the buttons and waited boot.
Now the charging light is blinking.on the dock.
Ok. Honest mistake. It wasn't charging. It blinks when active (connected to tablet and tablet unlocked...if you lock the tablet the dock led stops blinking).
Tried the cold boot thing described above. Didn't work.
The charger charges the tablet alright, but not the dock.
Opened it up yo see if there was something wrong (cable disconnected or so). Unplugged and plugged everything back. Still won't charge. =/
Any ideas????
Thanks in advance!
Got it to charge using a pliers. Images attached.
Apparently or my dock jack is bad or my cable connector...most probably the dock. =/
Any ideas on what to do now? Where can I get this jack? Is it not extremely hard to replace? Worth it?
I'm in Brazil, so I got no official ASUS support for this piece. =(

I have the same issue, and after reading your post, I tried your hack and the charging light finally came on for my dock. Evidence strongly suggests its a flaky electrical connection in either the cord or the jack. I am leaning towards jack because my cord will charge my tablet when directly plugged in, but I am not yet convinced.
Noticing that the connector's pins are on the outside, and it connects to a double-sided blade of pins, I tried to squeeze the connector some to make a better electrical connection. It was a little better, in that I could occasionally now get the charging light to turn on for a few seconds by applying pressure to just the cord's connector, but still not reliable. I then tried to use a small blade between the plastic and outer metal casing of the cord's connector, and I destroyed the came and now it won't even charge my tablet. I'll have to go to the store tomorrow to replace the cable, and we'll see if a new cord works to power the dock.
There's a distinct possibility that a new cable might just be all the fix I need.
Looking at the teardown on ifixit, it seems like the tablet uses a slightly different connector housing than the dock. Perhaps the dock has a less reliable part.

A new cable did not fix it.
Without another good path forward, I get brave and have attempted to reshape the receiver jack's metal housing to be more snug, hoping that a squeeze would do it. I have only managed to mangle it further.
