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.

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 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.
Anyone else notice that the wireless charging seems to be somewhat erratic in battery temperature increase?
Yesterday I put my phone on the WPC-700 and the battery temperature was up to 47C after about five minutes. I took it off the Qi charger, plugged it in to UBS and it was down to 35C. Today I tried it again on the WPC-700 and it is 37C after about 5 minutes.

Wireless charging = heat. Its a waste product of how it works and part of the reason why its slower to charge and less efficient. Its not the battery itself that's getting hot (at least not directly) but the coils used to capture the electromagnetic field produced by the charger.
Some chargers are a bit picky about alignment. If your phone and charger aren't aligned right, you can get excess heat and/or slow charging.
I see all the time where everyone likes to plop their phones down at an angle, relative to the charger, and while that may work with SOME chargers, it's definitely not recommended for all of them. Try placing your phone on the charger in exactly the way that the charger expects (look for a picture or diagram in the instructions or on the charger base). If this reduces your heat, then you have a picky charger.
Thanks for the suggestions. The actual battery temperature is warm, not just the device, significantly more than using USB. I"m just not sure if 47C is too hot or just right.
I have the phone aligned properly, I was careful to be sure the magnets grab best in how I placed the phone. I decided to order the Google charger and will see if there is any difference.
This is something I've noticed after using wireless charging to charge overnight for the past few months. I've been using the Nokia wireless charger, and in the morning the phone is usually warm. It's not hot. I checked temp and it's around 95F which is about how it gets after 5-10 min of browsing. I'm not concerned about the temperature, however I was just curious why I've never observed that with wired charging. I know that wireless charging heats up the phone more than wired charging, but after hitting 100% I thought it would act similar. After picking up the phone in the morning it feels cool when taking it off a wired charger. Granted, I've only used this one wireless charger for overnight charging. I have the nexus wireless charger that I keep in the car. I suppose I can try and see what results I get with that.
Anyway, just curious why you guys think. Again, I'm not overly concerned, but just wondering if the phone treats trickle charge differently when using wired vs. wireless.
Hi
I brought a Samsung wireless charger. The first few days, it worked flawlessly, but today when putting the phone on at 27%, when it hit around 85-90%, it started saying "Wireless charging have stopped" even tho it still charges. It's annoying, cause the screen light up, it vibrates and I get notification about it, but it starts charging right after?
Do you think this is a phone or wireless charger problem? Also, will this hurt my battery in any way? I mean if I leave it overnight, would it hurt the battery that the battery start charging, stopping again and then start again? This is around every sec or so.
Thanks in advance
Sometimes, that charger is finicky. You need to position the phone just right, and if it slides a little bit, it can start connecting/disconnecting. When it does that, try just picking it up and setting it back on the charger. I try to put just above center on the phone over center of the charger.
samsung S Charger Wide works
I bought the Samsung S Charger Wide qi charger, it predates the S6 round charger. It's also cheaper, although it does not come with a plugpack or USB cable. It needs a 2A charger (such as the one which comes with the S6). It charges easily even with the Samsung S View case in use. This older charge is about the size of Note. It has a slight lip making it harder for a phone to slip off.
does wireless chargers is fast as the fast charger provided?
No. It is a lot slower although the difference is much greater if your battery is very depleted. The performance gap is lower as the battery charges because the fast charger 'slows' down.
It's charging at 927mA according to GSam Battery at about 80%. That's not too bad.
