So, bought the following cradle from DayDeal's ebay store:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=350284094212
The product description says the following:
* Custom-fitted Docking Cradle
* USB connection/charging cable
* AC power adapter
* Stylus
Now the issue is with the second line. What is NOT explained here is that the unit when plugged IN to a wall jack AND the sync charge cable is plugged in to your computer, the sync/charge cable gets no more power from the wall jack and wants to get it from ONLY the sync/charge USB cable. All of this leads to the unit being grossly undercharged and therefore, complains that there is not enough charge coming from the power source and that you need to shut down and therefore the whole idea of a wall charger is useless after this.
WHY would a sync/charge USB cable which by the way is physically attached to the unit and cannot be removed, while the wall jack plugs into a proprietary mini-USB cable. I know it's proprietary because I tried first to use the wall charging cable that came with my TP2 from Sprint.
So, I'd recommend not buying this cradle unless you want to do what I'm doing now, have a USB sync/charge cable dangling from the unit and NOT plugged into the computer, but instead only plug in the wall charger and sync and data transfer via USB which is what I was doing before except now, I have a cradle to do it in.
Not a good trade-off to me. I bought this specifically to be able to sync/charge FROM the cradle.
One last thing, don't think about using the cradle if you have a skin or a hard case on the phone. The connector is so flush with the back of the charging stand that if you try to put anything BUT the phone into the stand it can't connect.
EDIT: December 5, 2009:
Been in touch with the vendor. They are going to swap out this unit for another one. They say that the unit doesn't do this at their site and that this one may be defective. I'll gladly swap this one out for one that works as unstated or at least expected. I'll post when I've gotten the new unit if this is actually a defective first unit or if this is the actual way these units work. And, I'll also try this on multiple machines so that I know it's not just my home desktop.
Another bad cradle from ebay DELUXE CRADLE W/2nd Battery Slot FOR HTC TOUCH PRO 2
When AC plugged in and USB to PC the PC USB sucks the power so the phone charges slow or not at all. Also doenst seem safe for the USB to send the power back out to the PC from the cheapo AC plug in this cradle. When used as a standalone charger AC only it sometimes fails to charge, about a 50-50 success rate. Stay away from it.
That's good info. It is the exact cradle I bought, but i bought it just for charging. I have not used it for connecting to the PC yet, but i needed a cradle that had a slot for a battery in it too.

I purchased this cradle and my complaint has to do with the USB cable that is attached to cradle. I need a long line to reach back of my PC. This attached one does not reach unless I want to view the phone from 5' away! Very disappointed. I've only had it a few days but didn't know this, sanjsrik:

It does seem slow to charge but I'll run a couple of tests to confirm.
Today while I was plugged in I noticed my TF was not getting charged. I checked all the connections, rebootedthe device, and still no luck. I plugged it into my laptop and it was recognized as usual, and even charged up 1% over 10 minutes. I then plugged it into an old iphone charger and it charged a bit faster.
I tried the Asus AC adapter again and it didn't work. I called Asus and explained the issue. I was told I could order a new charger through estore.asus.com. Of course they don't have them in stock. I called the store and they recommended I contact customer support again. I called them back and they said my only option was to wait until the estore got them in stock. They said I couldn't RMA the Adapter at all. The rep said he couldn't confirm if the adapter was covered by the warranty!
I'm really frustrated right now, sorry for venting.

Man that sucks & what a ****. Try calling again & hope you get a better CS rep. GL to you.
Apologize for asking a trivial question; have you made sure that the wall adapter has locked into the charger correctly? There are two prongs in the adapter that need to click into the charger unit. I ask since I had a hard time figuring this one out
Does your TF battery discharge when plugged in? I have noticed others on here and some other sites talking about a charging problem. I got my TF today and plug it in right away since it talks about charging for 8 hours. It went from 35% to 100% pretty fast. After it got to 100 I put it on the dock and plugged the dock in. At some point the dock got a green light. At that point I hit the battery icon and saw it said 98%. It has stayed there for the last three hours with everything plugged in. The thinkpad I have at work has a preset threshold for when it starts charging. Supposidly this is for the battery health. I wonder if the TF wont start charging until it drops to a certain level. Even though my TF doesn't show charging at 98% if plugged in directly or through the dock if the dock is plugged in the dock shows a green light.

Yup. Devices will only start charging at 89-90% until full. If you disconnect the charger before it's full, most will not continue charging, until again depleted below that threshold.
OP, try turning the device off completely with the cable out (hold the power button for about 15 seconds). Then, when off, and the cable plugged into the charger, plug the charger in to the device. If the charger is working, it should power the device on, and hopefully, you'll see the charging icon.

Don't know where you are in the world but in the UK they _can't_ exclude an integral part like that from the warranty. If the person on the other end cant verify if it's under the warranty I suggest you tell them to get someone that can. their lack of internal communication is not your problem.
I got the same problem.
I got my Transformer last week and I encountered the same problem. When I first called the Asus support, the guy told me that my option would be to send the whole thing to them because I did not know at that time that it was the adapter. I told him that I would return the machine to the store that I bought instead. Then, I started testing by plugging it to my PC and it worked. I also plugged a USB light to the Asus adapter and it did not do anything, so I called them back the next day. I got a better support person this time and he told me to send the adapter back to them. I got the RMA number. I know that they probably don't have the replacement yet so I will have to wait and see.
In the mean time, I find out that the iPad AC adapter will charge the Transformer a bit faster than plugging into a computer. However, it is still not that fast. It takes several hours before charging from 60% to 100%, but it is not too bad. I will have to leave with it until I get a replace adapter.
I have tried completely powering the tablet off and plugging it in, it does nothing. The adapter worked fine for about a week, but now it's toast. I'm going to try and call Asus again today and see what I can do. It's sad that others have had the same issue!
I'm going to try and find an iPad charger in the meantime.
Replacement adapter?
As I said before, the iPad AC adapter will charge the transformer but it will be slow. I tried to find a replacement adapter but I could not find anything that will provide 15V and 1.2Amp. I think the iPad adapter will provide 5V and more than 1.2Amp. Does anyone know an AC adapter that will provide more voltage?
FYI I've tried emailing Asus about getting a spare power adapter. They weren't particularly helpful:
The Travel kit is currently not available for purchase. Unfortunately we can not give a time estimate when this product will be available for purchase. For availability and price please contact your local retailer.

Even if you happen to find a 15v PSU with a USB connector on it it's unlikely to work as it would nee dto put that 15v on the right pin. The USB3 socket is not supposed to have 15v anywhere so the pinout can't be anything like a standard, they just happen to be rolling in 2 uses (USB sync/+15v Power) into one port.

there have been other threads about this. usually its the charger overheating and putting it in a ziplock in the freezer, resets it.
Mine did that too, just leave the charger and everything unplugged from the wall for a day. That fixed mine.
Sent from my ADR6425LVW using XDA Premium.
The other issue I've seen is poor contact in the USB socket on the wall adapter. I had to unplug the usb cable from the wall adapter. Then, look at the usb socket on the power adapter. The gold pins are the usb contacts. Directly opposite of them, there should be two silver prongs. I had to use a small flat blade screwdriver to pry both of them out a little further to ensure they did their job of firmly pushing the usb cable against the socket's usb contacts. Once I did, my TF201 was able to get charge from it, again.
If you decide to replace the wall charger, I believe Fry's and Office Depot stock the asus charger.
Same thing for me.. PC recognizes it as a media device, but will not charge with wall charger. Wall charger works with my HTC Phone, so it works.
I don't think it has anything to do with the latest update, since the Dock wont charge either, and there's no OS in that, right?
Just experienced this today. I have had it unplugged for about 10 hours now, we'll see if it charges.
I had the same issue few days after I got my prime. I connected my sgs to the charger and it worked. Then connected the prime and voila-works.

C1. There are some good suggestions here I need to try.
Wrap it in a towel and bang it against a table. That will fix it usually. Then get some pc heatsinks and some arctic silver adhesive and you can attach them to the charger to keep it from happening again.
The plug has two options, 5V (standard for USB?) and 15V. I used the plug on my old HTC phone (Ozone) and then plugged it back into my Prime and it worked. Thanks for the great tips guys.
Since the charger works in two modes, I wonder if some charges became confused and started dishing out 5V when they should be dishing out 15V. Thoughts?

Hi, I got the same problem. The charger indeed seems to be stuck in the 5V mode, since, when plugged in the tablet does get charged, even though it is not indicated, but very slowly. It is charging as if it is plugged in to a pc.
I tried plugging it into (old) phones, but I still can't seem to get it to switch back to the 15V mode.
The freezer didn't help either.
Any other suggestions?
I waited about 4-5 hours before plugging into my old phone. My other suggestion is to allow the phone to charge for a short bit (30 minutes) unplug and wait, then plug into your Prime.
I have a feeling that its a transistor toggle that isn't flipping at the correct voltage.
I've had the same problem yesterday. In my case the problem was with the charge socket on the keyboard itself. Some copper pins were deformed and that stopped the device charging. I took a magnifying glass(also for checking if any of the copper pins are bend) and a small tool to bend them back. After this it charged again. Hope this helps.
My charger suddenly stopped working from today. The Prime is detecting the connection as the screen turns ON but it is not charging. I charged my sensation using the same adapter and USB cable and it is working fine. Why can I not charge Prime via PC like phone? Is it possible? I am in India and not sure if the power adapter is easily available as Prime is not yet launched in India.
Kindly suggest.
Thanks in advance.
Hi,
I've started to have this problem today, plug it in and it does come up with the charge icon but it doesn't charge - or doesn't seem to.
However I left it connected last night from midnight until 8am this morning and it went from 13% to 17% so it is charging VERY VERY slowly although the unit doesn't actual seem to think it is.
I have it plugged in to my phone right now and its working perfectly, I borrowed the charger to my g/f last night to charge her iphone and i'm thinking this might have done something to flip the voltage as since then it isn't working.
Anyone have any ideas on this??

But if the charger works fine when charging a phone it cant be the connection at fault..
It does seem to me that the power it is outputting has dropped especially the I managed to gain 5% over the course of a night where WIFI was off and screen was off even though the charge icon doesn't come up.
Is there a way of forcing the charger back in to 12v mode??
damnit... I had the same problems a few days ago and I thought it was in the cable instead of the charger... not realising the charger has to put out 15v instead of 5v.
Does this mean the Transformer won't charge with for example, my HTC charger?
I totally messed up my cable, because I thought it was broken... when I opened up the USB plug, I noticed the yellow wire was not connected anymore, but this didn't solve anything. Eventually I messed up the cable that bad, that I've ordered a new one from ebay... but when I read this... I should have just banged the charger a few times... shait.

Has anyone actually ever managed to fix this problem? I've just contacted ASUS about it to see what they say - hopefully they'll ship me out a new charger plug or something, what a useless charger!!
Does anyone know if there is an official 2m USB cable available in the UK? I bought a generic one off eBay, but it charges the phone extremely slowly....

Are you charging the phone from a USB port? If so, it's the limitation of the port, not the cable. Try with a proper charger an it should charge at a more sensible pace.

Charging speed doesn't depend on the cable but on the charger it is used with.

I'm afraid it doesn't work as well for me. I got a Kindle 3 cable, and while it does charge the phone (using the charger which came with the phone), it does it very slowly. So slowly that if I try to use the phone even for basic tasks whilst charging with it the battery still keeps heading south.
If I use the stupidly short cable that came with the phone it charges nice and quick, but every other cable I have used so far either doesn't charge or does so very slowly.
Any ideas as to why this would be?
On a related note, this sounds good, but again the cable looks stupidly short:

What are you using to charge your phone? An EP-800 or something else? I have a cheap 1500ma charger that seems to take ages to charge my Xperia. The cause was that for a full speed charge, pins 2 and 3 must be bridged. I dismantled the charger and put a tiny blob of solder on the usb port pins. It now charges like a demon.
Same story with my car charger. Before the mod I could actually lose charge when using satnav and streaming music over bluetooth.
I have a battery widget that says whether I am on AC charging or USB charging. Its name eludes me.
Oh, and a safer alternative may be to sacrifice a USB cable and bridge the pins on that.
Better than all those though is the official Blackberry Playbook charger. 2A and a long cable. Charges the phone like nothing else.
Yep, am using an EP-800.
Fortunately the latest cable I ordered works a treat, so I can happily recommend this one:

Hi,
Where I charge my TF300T, the cable is too short... and when I plug a usb cable extension, no charge. A friend tell me it's possible that if I want to extend the cable, I need a USB3.0 extension...
So? What cable I need to extend the lenght of the charging cable?
Thanks!
Same. Tried multiple extention cables (though no specific USB 3.0 extenders) and no dice. It will not charge, even though other devices charge flawlessly even when I plug them into a USB extention cable (iPhone, Samsung Galaxy's, PS3 controllers, camera's, etc.)
However, the Power output of the AC adaptor for the TF300 is either 5V - 2A, or 15V - 1.2A (in contrast to the power requirements of the above mentioned devices, which are tailored to comply with USB 2.0 standards). Default power draw on USB 2.0 on Battery Charging Spec 1.1 is 100mA (1A), so that would definitely seem to be the problem. I however haven't yet had the opportunity to test a USB 3.0 extention cable, but I would assume these would do the trick, since USB 3.0 (or Battery Charging Specification 1.2) should be able to go up to 1.5A with a 5A max draw.
This thread for the TF101 shows why USB 2 extension cables don't work, and how to mod one to make it work.
A USB 3 extension cable would work too.
Consider getting the usb cable extender
Sent from my Galaxy Note or from my Transformer TF300T
I have used the Monoprice USB 3.0 cable extender mentioned in the thread for the TF101.
I also bought an after market longer cable from Amazon that works great. Link here:
http://www.amazon.com/gp/product/B007EIZ9B6/ref=oh_details_o06_s00_i00
i can confirm that the blue monoprice usb 3.0 extension works perfectly. i originally got it for my tf101 and am glad that its still useable on my tf300.
Here is a solution...

if you are just looking to wall charge it, get an extension cord at the dollar store
thats what i use
extention cord will be best.
thanks for the links. have been wondering about cable length and didn't want to add another cord to plug into the wall.
does the cable change when plugged into a PC? wife took off with laptop and didn't notice when I rooted.

Did you mean me does it charge? If so then the answer is yes but not fast. It is pretty much a trickle charge when plugged in to a PC. A pc does not put out a large enough charge via USB for the tf300 to charge properly. It would take forever for the tablet to charge.
You need a 15v plug like the one that comes stock with the Transformer.
Pretty much the only thing the USB cable is good for with a pc is to transfer data.

Hey,
I had this similar problem with my asus TF300T, I used to have a cable +-1.5m long or longer, then I had to send it back for repair.
Couple of days later I received a new charging cable, though it was 1.30m long or less. Which is very uncomfortable when using the tablet at the same time as it is charging. So I phoned Asus Support. They told me that it is indeed possible that some tablets are sold with a smaller cable. These are most likely the newer ones.
I asked if I could send back the shorter cable (which was broken upon delivery) and receive a longer one as the one I used to own.
They told me that Asus has stopped making cables any longer then 1.30m. Though costumer service had no clue why.
They suggested me to send the cable back and to include a note in the package that I used to have a longer cable and I would like to have a similar one back. Of course I was very polite etc, and it worked!
So as Asus' costumer service says : "Asus themselves owns very few longer cables, they don't produce the longer ones anymore and moved to a shorter standard cable. Only if you are lucky you can get your hands on an older long cable".
Of course this doesn't stop you from looking for other third party cables.
