My cousin just got this tablet a few days ago. She likes it alot, but she said it get's really hot while charging. I have not been able to see/feel it myself since I live in a diff. city, but I am trying to find out for her if this is normal for this model. This is her first tablet so she is worried if there is something wrong or not.
It's a fairly high power charger, they get hot when used. Unless it's so hot she's worried it might melt or catch fire, it's no problem
The TF700 charger is rated at, what, 12-15W? That's quite a lot of power in such a small device. Have you ever used one of those small iPhone/iPad chargers? They get pretty damn hot as well.

She has a iphone and never has complained about the charger on it getting hot. Would it be correct to say that the asus charger get's significantly hotter than the Iphone charger?
I wouldn't say my TF700 charger gets any hotter than my iPhone charger.
I did just realise when re-reading your post that it might be interpreted that the actual tablet gets very hot while charging? Or is it the charger?
Either way, a battery gets heated up when charged, so both the charger and battery/device itself can get hot, although neither should get so hot that they're uncomfortable to hold. If it feels like you'll burn your fingers holding it that's a bad thing. Otherwise it should be fine

I was playing Ocean Tower while charged for several hours, the tablet itself got VERY warm, the charger itself was also quite hot. Not hot enough to burn me, but definately hot enough that i didnt want to touch it. I think im gonna stick with it for now, if it does start melting then im gonna be going directly back to the store and make a lot of noise. No charger should get hot enough to create a fire hazard!
We should have some prime users who upgraded to comment here.
I upgraded from the prime and don't remember the prime getting warm like the infinity when charging. The infinity gets quite warm, close to being hot.
Not to be contrary
...absolutely no hotness with the Infinity tablet here (maybe just lucky me)
The little charger brick...yes that thing gets warm when charging from say 17% to full up.
I switched from the Acer A700 to the Infinity.
You want warm try the Acer HD tablet.
The charger of the infinity gets about 50 °C when charging a long time but that's no problem
My charger gets hot as welll when it is charging the tablet/dock. Not so hot that i think it will set my house on fire while I'm asleep, but inconvenient to touch, yes. As Einride said, though, most high-powered chargers get hot.
As for someone mentioning the iPhone charger and it not getting hot: that is not a high-powered charger, and neither is my SGS2's. Not all crApple products are high-powered.

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.

I have a power plug and sometimes charges and sometimes don't. It also gets hot after about 10mins of charge but it is charging.
I know there has been a few faults but has anyone experienced this charging sometimes and hot to the touch?
The charger getting hot is a good sign; that shows that it is working. The charger will get (very) hot during charging and will cool off when it is done charging.
My recommendation to fix the sometimes charging/sometimes not charging problem is to pull the cord out of the plug unit and plug them back together. The cord is a little finicky and so it might need to be reseated. Make sure the cord is plugged ALL the way into the plug unit (it can be a little hard to get them to be perfectly together).

I have called Asus on this issue and while they agreed to RMA the charger I just can't be without it right now so i wait. Chargers getting warm are normal, but chargers getting as hot as mine does is not normal and not good. I would estimate this charger is getting in the 160-180 degree range. Mine has also failed to charge on one occasion. One post i ran across said to change the polarity of the charger by turning it over so that the word ASUS is upside down when the viewing the outlet with the ground pin below the prongs. Seemed to help but not sure if its actually better or just wishful thinking, ymmv.

Turning the charger over does not effect the heating of the charger, it simply eliminates the possibility of stray AC voltage on the shield of the cable and frame of the TF. The heating of the charger is caused by inefficiencies in the inexpensive charger and fact that it appears to be working close to its design limit. A few tips that have worked for me.
Use an outlet that good air circulation around it.
If used on an extension cord. sit on a heat conductive surface not on a carpet.
If tablet and dock are deeply discharged, charge separately and allow charger to cool between charge sessions.
If the charger gets too hot, it appears to shut off. Allowing it to cool generally gets it going again.
ASUS said i spoilt the power plug
sigh...i bought 2 units of EEE PAD **** TRANSFORMER...2 of the power plugs also loose...after 2 weeks of use...they said i spoilt the plugs and is not under warranty..i need to buy replacement...
how low quality is ASUS product or eee product...????

The charger and plug for the wall are a 2 piece unit. Ensure that that end that contains the wall prongs is seated all the way down. There is a line between the 2 units. The pieces on both sides of the line should be flush.
Regarding temperature, mine gets pretty warm. Warm enough that I would not want to handle it.
My Eee pad came with a UK power adaptor. I have noticed the adaptor gets very warm even after it has been charging for a half hour or so. It's a lot warmer than I would expect. Is this normal behaviour?
Seems to be. Mine gets warm when its charging, when the TF isnt plugged in or the TF shows charged it cools off. Not hot enough to melt anything but definitely warm to the touch, even warmer than my laptop adapter. Although, I should note it gets nowhere near as hot as a kingston laptop adapter I rented from Best Buy a while back.
My adapter gets super hot when I plug in my tablet when docked and both have dead batteries. After seeing pictures of people's adapters melting, I won't let mine charge from dead unattended.
i believe its warm due to the high charging rate. considering the fact that it only takes 4 hours to fully charge a tf from flat.
from personal experience, charging batteries at higher C the charger itself will warm up.
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.

Mine ddiid the same thing last night as well and was wondering the same thing. Since the house didnt burn down I am assuming all is well.
Sent from my Transformer TF101 using Tapatalk
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. :/
New tf700t. Let batteries deplete to teach battery monitors.
Keyboard drained, tab 12%.
Plugged in AC Adapter, wifi, and surfed web.
After a few hours I wake up smelling hot plastic.
Well, adapter is blazing hot. I needed to grab towel just to unplug so not to get burned.
Very disturbing as I was in bed watching TV falling asleep.
I'm very careful with anything that could cause fire.
.
?
Did I use charger properly?
Are some chargers defective?
I just installed chromi-x Rom if it matters.
Using battery operated devices at home I typically have them plugged in during use so close to fully charged when hitting the road,
.
Insight appreciated.
Cheers
The charger can get warm, but if it gets *that* hot, I'd say it is defective.
Interesting - I just went and felt mine. It's really freakin' hot as well.
Question: Have you removed the clear protective plastic sheet on it? I hadn't, but now I have.

It was blazin' HOT. Hot enough to freek me out.
I'm a green noob, but do know _that wrote the kernel im runnin' so the adapter is getting trashed.
Since it's sort of customized w/15V I'll try to find oem replacement.
thanks much.
It's normal for the adapter to get warm while charging, but it should not get hot to-the-touch. I would say the charger is defective.
I'm not sure. Mine gets uncomfortably warm as well. Always has.

I imagine you would know.
Do you think hot adapter may be a function of the state of each battery ie < certain life % remaining, while charging with tablet on, in use, wifi on etc?

Not sure. I have an Asus prime and an infinity and both cause the power pack to get what I would term hot. They always have. Asus chargers are funny as they deliver a much higher voltage and therefore generate more heat. Comparable with a laptop power pack maybe?
Ha, OK. Maybe I'll mount a heat sink or cpu fan to the darn thing.

Heat output is proportional to power (voltage * current), not voltage alone - and inverse proportional to the efficiency of the power supply.
