I got an XDA II from my dad, it had to charger. So, I got one off of eBay for all of £3.50. Within 10mins of it been connected it blew up?!?! I am being deadly serious, it actually did.
So, after getting my money back etc, they did not want their old unit back. So, I thought i may aswell put this to some use while my new charger (from a diffferent place) was delivered. So, I snipped the connector with some wire attached, rigged it up to a USB connector (As below) and there we have a nice DIY USB Charger.
The pinouts are as follows:
- (GND) Pin 4 on the USB
Pins 16,17,18 on XDA Connector
+ Pin 1 on the USB
Pins 20,21,22 on the XDA Connector
Its charging away quite nicely now, but I shall report back on the actual rate of charge because from what I gather the output of a USB is 100mA whereas the charger had an output of 200mA.
Hope you find this useful
no usb provide 500mA to share for all usb devices connected to the port
unless a powered usb hub is used in which case every port in the hub provide 500mA
Ah, Its going through a USB 1.1 hub... which has no external power.
Though, today.. my replacement arrives. Thanks for the help though, the information about the web is a bit vague.
C series serial number prime worked for three days now won't take a charge. Device will connect to pc or mac via cable, just won't take a charge. Any ideas for me?

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.

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!!
Hi everyone. I own a GS3 that has been running flawlessly for about 3 weeks but since last 2 days it has developed a problem whereby it only charges via the laptop USB port and not the wall charger. I have tried factory reset, flashed two different custom ROMs based on two different firmwares, pulled battery many times, etc etc, to no avail.
the phone starts charging from wall charger, but after a few minutes, charging stops. I have used the original Samsung charger, my old HTC charger, with a combination of many different USB cables and the result is always the same. The USB port appears to be undamaged
ny suggestion to fix the problem?
Android 4.0.4
I9300BWLH1
Kernel SIYAH S3 V1.5.2
Well from what i can see the problem doesnt lie in the data cable. So maybe it the wall plug section. Or maybe the the socket itself maybe be faulty.
Problem doesnt seem to be in the phone itself so nothing to worrry about too much.
Maybe buy a travel charger to see if that helps.
Also high recommended that you do check the plug socket to see if anything else charges in there.
Might be worth charging in a different plug socket.
Hope this helps

the data cable IS OK !!
How about the plug socket. Have you tried to plug something else into the same plus socket to make that it still charges for example plugging your laptop into that same plug socket that your phone was to see if the laptop charges.

the result is the same.

Well I thought my phone was broke last week...
It wouldn't charge so I tried my old HTC charger and that wouldn't charge it either but it would via usb to laptop. So I purchased a new wire and that worked, I then tested my HTC charger on my HTC Desire HD and that still worked.
So the SGS3 doesn't seem to charge using a HTC cable unless connected to a computer. Try purchasing a new genuine usb cable
Alternatively, you could wipe battery stats in CWM (in advanced menu) and see if that fixes it

I had the same trouble, only 3 weeks after I bought my SGS3.
I did go to Samsung repair center, and they change the motherboard (under warranty).
2 Month before, same trouble with my SGS2, unfortunatly no warranty.
Samsung ask me for (around) 300$ for motherboard, and I did not do.
I've removed batterie and charge with external battery charger .... and forget it a while.
When I try it later, it was working fine ! What was my surprise !
I can charge it again with charger.... two days after "same player shoot again" : impossible to charge ... then work again :silly: !
I'm having this issue too. There is a whole thread of people having charging issues, and I assumed my problem was the same, however upon further inspection it charges via PC USB cable. That said, this may be the issue with the others in that thread.
My phone definitely seemed to charge by powerpoint when I first got it, but has since stopped.
Charging by PC is a pain, as I use my phone as an alarm, and my PC is in another room.
edit: the lightning icon comes up when I plug it into the wall charger, it just gets no charge. Is this the same as everyone else?
Bought one of the 3FHUBEG HDTV adapters today to mirror my S3 onto my tv. According to the guide i should plug the official charger into the adapter and then plug the charger into the wall. When i do this i get NOTHING on my tv screen and the phone will not charge. I thought the adapter was DOA so after trying many things i removed the wall charger and instead i plugged the usb into my pc and voila it worked and the phone started charging and the S3 mirrored onto my tv.
It seems to be working okay this way but why isnt it working when i plug the usb end of the charging cable into the uk plug adapter and then connect it to my socket? Would i be doing any damage by just powering it via usb on the tv?
Im really confused. I charge my phone normally overnight and it works no problem with the usb charging lead plugged into the wall socket and then the micro usb into the phone but for some strange reason the phone will not power the HDTV adapter this way and will only work by USB power and not mains power. Any help appreciated. :good:
Check your cable first, some of them have 4 pins only and this can be a reason. If not, I'm not sure but wall charger have 1A output and this can be too much for adapter. USB output is 550mA so nearly half of it. Charging from USB won't damage anything, it'll only take longer to charge your phone.

It's definately a 5 pin and its an official cable. I'm just concerned as every video i've seen etc shows the charger being plugged into the wall. When i was charging it via usb, as its a slower charge, the phone seemed to be losing more power using the HDTV adapter than the charge was capable of charging, i.e the phone battery was draining power quicker than the USB could charge it. Absolute mystery.
Hmmm, maybe it's just so badly made...

Wouldn't surprise me with Samsung. I actually bought this adapter so i can stream certain things from my phone to the tv as the browser i have on my Samsung SMART tv is pants. Common theme developing here :silly:
Ok I've been using anker batteries for about a month now and I bought the two batteries and an external battery charger deal. So I haven't been charging my phone through the modified micro usb port on the bottom but putting a fresh one in every morning and taking the one out and placing it on the charger for the next day. Today I used my phone super heavily and needed to charge it when I got home. I plugged it in and nothing. I've switched plugs, switched cords, etc. Ive also plugged it into my computer and it goes into usb debugging mode so I know the port still works. Since I know my plugs work, the charger works and the port works what could be causing the phone not to charge?

Have you tried the OEM battery to see if it will charge in the phone?
