So im seen alot of q's asked about "epad wont turn on" or "charger broke"
Just to let people no 9 times out of ten when you tf wont turn on people tend to think its finished and say there good byes. But a member here has said that theres a problem with the cargers and that putting it in a zip tie bag and putting it into the freezer for 30mins will help.. supposedly the boxy part of the charger has heat sensers and there reading the wrong temperatures so thats the idea of the freezer..
Some user said this helped there heat issue too.
*make sure it a zip tie bag/air tight bag to keep moisture out..
If people whos pad still wont turn on plug it into a laptop/computer to allow a slow charge for approximately 3 hrs and see results
Last resort is to buy a new charger with specifications of output values of 15v/5v
Charging at 1.2A/2A
I write this because i was afraid it would happen me at some stage so i did the searching so you dont have too

The answer is simple. You've paid good money for it.....RMA the charger for one that works.
Even people whogot replacement chargers were complaining

Yeah I had the problem once with the charger overheating itself while I was charging my phone off the USB in the keyboard. It hasn't done it since but it's nice to know that it's a "known issue"
Is it ok for you now

The question should be.....
What is classed as overheating?
This has happened to me in the past, and its actually a really simple problem.
More often than not, melted charger connectors are a direct result from charging a device like this with the connector loose, crooked, or not fully inserted.
Our transformers require bit more power than a standard USB connector can provide. As such, the charger connector has a redundant pins for power, to spread the current flow over more than one contact point. This reduces the current flowing though each individual tiny contact point, which is supplied by a tiny wire, and thus keeps the temperature in check. If one contact isn't able to make connection due to a loose connector, crooked or incomplete insertion, more current has to flow through the other contact points which basically begins to overheat.
This problem isn't just related to chargers and things like that. Any devices which you contact points and flow a reasonable amount of current can do this. I've had it happen to a friend who didn't properly seat the DIMMs on his motherboard, and basically overheated some power leads on his DIMM sockets:

nice! I had the same problem, my TF was not charging anymore. I took the charger out of the wall-outlet and let it lie on the ground for a whole day. The day after that one I tried the charger again and it worked again!
Thanks for this nice and helpful information!
This actually falls more under general and useful information than Q&A, so I am moving this to the correct area. Thanks OP for writing this.

I've seen a post somewhere where members are stating that the phone sometimes stops charging from the power supply. I had this tonight and when playing around with the charger, could hear arcing. It's due to the slide in plug part not making good contact with the pins. Evidence of this is a blackening of one of the metal plates inside the socket part (not the pins on the main charger part). Suggest you check your charger, as prolonged arcing is not good.
Another one here, I'm afraid.
The main part of the adaptor has silly silly bits of sprung metal that are supposed to contact with the smaller plug part. Unfortunately, on mine the two parts are rather loose it sometimes does not connect.
I hope that my supplier won't want me to send the whole phone package back otherwise it's going to cost more than the value of the adaptor to send insured.
Keep an eye out for this, folks. As the previous poster suggested, it could cause overheating.
- Steve
Update :
HTC Europe have just returned my mains adaptor, still intermittently faulty.
I've sent them a stiff letter with images of the pitted and blackened contacts caused by the mains arcing.
If that doesn't produce an acceptable response, I shall escalate the issue to a third party because of the potential safety issue.
Update :
HTC returned my power supply saying that they cannot find anything wrong with it. Not happy !
Obviously, because the problem was intermittent, they must have tested it briefly and not seen the problem.
I wrote to HTC UK enclosing pictures of the burned and pitted contacts. No reply.
I imagine that I shall now have to persue warranty through the original dealer (Handtec, who don't really want to know anything about faults after the first few days, but nevertheless have a legal obligation to resolve the issue).
Unfortunately I can just see myself going round in circles with HTC again. Grrrr!
Since its not a computer item you have to prove that it isnt working, which technically shouldnt be to hard since you have burn marks, if they continue to say noting id be temped to get a qualified second opinion from someone and get it on letter headed paper, if they refuse to do anything after that you can say you have expanded all reasonable efforts to fix this issue with themselves (HTC) which is a potentially life threatening issue, you have not had a satisfactory responce to date (DATE IT) and if you have still not recieved a reply / replacement within 14 days, the next communication will be from my solicitor, where matters will be taken further, on the grounds of faulty electrical goods proven to be faulty and not being replaced.
Try that and see what happens, course getting a solicitor might cost an arm an a leg for the cost of what? a £20 power adaptor...
Yes, it's frustrating.
I should have no problem getting an assessment from a qualified engineer - I work as an electronics engineer myself in a safety-critical industry (aerospace).
I'll give Handtec fair chance to solve my problem first before wheeling out the big guns ;-)
Here's an enlarged photo of the contact inside the plug half of the adaptor. You can see where it has started to arc :

My charger did this too!
Called up orange and they sent me an entire new handset and i had to give back the old charger, battery and phone. Leaving me with 2 8gb cards, 2 spare stylus', 2 cases etc...
So i'm not complaining

My HTC charger stopped working just a few minutes ago, luckily i had a 750mA USB charger which i bought for 5 bucks lying around and that works perfectly, charging it with that now.
Recently bought this on e-bay... (I'm from australia)
http://www.ebay.com.au/itm/320709658351?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
Unfortuantly I gave a positive feedback without doing extensive testing. With this set I find that when connected the battery was being drained from the phone at an astonishing rate (about 5-10% per minute).
I had to turn this one upside down for it to fit in my Mazda 626 because of the position of the cigarette lighter. Shoudn't make a difference though.
If anyone can recommend an in car charger that works I would appeciate any information.
I got this one:
http://www.ebay.com.au/itm/New-USB-...ronics_Batteries_Chargers&hash=item2c5ef94c72
And then just connect your data cable or buy one from here:
http://www.ebay.com.au/itm/High-Qua..._Accessories_Wires_Cables&hash=item4cf751cce0
The biggest advantage with this one is that you can recharge pretty much anything that has USB cable...
I found this one in local shop:
www.cellularline.com/catalog/en/cat...to/carica_batterie_da_auto/roller_car_charger
I like the roll-in cable, no hazzle with cable lying around. Maybe a little slow charging, about the same as computer usb port.

I use one of these, having 2 usb ports is handy since I can have my x5 and the wifes u8150 or 1 of the phones + ipod charging at the same time.

I had a general cigarette lighter to USB which I used for my previous phone... works just fine.. no need to buy anything specific.. anything should work
I bought one car charger for my U8800 but it shows different voltage in the specifications. That couldn't reduce the battery life? Or it only affects the % of charge of the battery?

You have to know, that I have bought 2 car chargers and they both draining out my battery. Some other guys that have been talking to, have the same issue. We came to conclusion that it has got to do with the rom or the kernel...

So your chargers are discharging your battery?
Why would this be rom or kernel related?
Read the links with Google translate, very hard to understand what the problem is. Could you try to explain more.
My friend, we are not sure what the problem is and all you could find in the above links, is only the proble, not a sollution... I just pointed them to saw you that this hapens to others as well and that the problem could be something else than the charger...
we concluded to be a kernel problem because if i have a stock rom the same usb charger charges normally but if i have a miui/cm/oxygen rom the same usb car charger discharges the phone. any help/solution/fix is welcome.
Does it working? I've bought one, but mine doesn't working...
I have just update to official 2.3.5 and the problem resist. So, maybe it is not the rom after all... I dont know.
I bought a cheap one from DealExtreme: http://www.dealextreme.com/p/car-cigarette-powered-usb-adapter-charger-blue-dc-12v-24v-36212
Works fine. And I had an old cheap one, that one worked too. Are you attaching a charging cable or a data cable?!?!
Tcm9669, this solution is good for charge everything with each device's orginal usb cable. I buy it from local shop for nearly same price.
No, I actually charge with a different cable I bought again.. from dealextreme (designed for HTC) it's not the original one.
Anyone tried this?

My review on this product is basically this.....
This product is amazing in every way it's described. Small, portable, lightweight, lots of energy, and can charge anything.
It comes with 2 ports to charge (can be used at the same time), and 1 port to charge the actual battery.
Can charge my iPhone more than 6 times....I have not been able to test it efficiently, but it works, and it works well!
How to describe this product....
Think of an iPhone 4 in a Otterbox. Now imagine it was a bit longer like an iPhone5. Now imagine that it looks like an iPhone, yet there isn't really a screen, it's just for looks. Now what you do is you put this charger in your pocket with your phone when it's getting low (or in the car, in a bag, purse, whatever), and than you instantly have POWER IN YOUR PANTS.
I've been questioned....why do you have a wire coming out of your pants? How are you charging your phone while walking around? What type of magic is this?
On a more serious note...everyone phone dies...everyone wishes they could charge their phone while moving, and they also wish their phones would never die. This device does that and more.
It's programmed to charge iPhones and Androids faster than normal.
It comes with a ton of connectors to charge tablets, all phones, laptops, and basically anything I can think of.
for $40...it's a steal. Buy it, you'll love it. Thank me Later ♥
My review on Amazon is very basic, and lists the only two flaws I saw....
1) The iPhone connector will unattach itself from the provided cord that comes with the device. I think the same applies for Androids, and tablets. I suggest using the standard cord your device comes with to connect to the external battery.
2) there's a lot of important attachments that come in this very small bag, and all the pieces are very small. None of them are really needed besides the USB cord to charge the battery, but I wouldn't want to lose them, and yet they are so small...I likely will. Wish there was a small zipper in the protective pouch it comes in.
Conclusion:
★★★★★/★★★★★ (A universal product that should be owned by everyone)
Cost: $25-$40...I suggest buying the largest one, simply because it's an amazing deal. I bought it for $50 not too long ago, and it can be a life saver. (Think about the shows where you get lost in the woods, and your phone dies) ^_^
Edit: basically changed my review on amazon to this. Hope that's alright with you guys.
where is the link for this thing or even a name for it to buy? i am not seeing it. sorry if i missed something.

Hi guys,
I just got done modding my Note 2 to do wireless charging and I'm extremely happy about it!
It is super easy and simple. Unscrew the back, solder copper tapes on the terminals that already exist.
It would have taken me 5 minutes if I had a good soldering iron... Mine sucked really bad (the tip wouldn't heat up right) so it took more like 10 minutes.
Here is a Youtube link to a nice tutorial: http://www.youtube.com/watch?v=rDSyjl_2CXo
Here is a cheap wireless tag + charger for Note 2 from China for $50. Took 2 weeks to get here. (Cheapest I could find for both coil and charger) It works great. Charging distance is 5mm and output is 1000mA. Not fast but good enough.
http://www.ebay.com/itm/170995097433?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
When you get the wireless tag you just need to heat up the terminals and take them off. You can leave the terminals on, but it's pretty thick, adds about 1-2mm of thickness so you'll need to buy a bigger cover to use it without taking them off. Tutorial here: http://www.youtube.com/watch?v=J5bnenaI86I&feature=youtu.be
The wireless tag adds very slight bulk, maybe a slight curve where it bulges out the most, but the regular backing will close and it's barely noticeable. Especially since I use my Note II in a case I won't ever see it. It may bug some people that don't use any case or cover.

Here is my Note II charging.
I found that wireless charging on a flat surface was actually too big of a hassle... I had to position it right and trying to operate the phone while charging was difficult because it would slide off.
This was what I had in mind when I did the mod, to have it in a stand. I had a Belkin Flipblade stand, so I put the charging plate there and now all I need to do is slip the phone in it. (I had to attach some stuff in front to keep the Note from sliding off the stand as you can see)
I did this mod because I wanted to be able to sit in front of my desk, slip the phone on a stand which will automatically start charging, and listen to music through my Logitech speakers wirelessly. (Bluetooth audio receiver is on its way as I write...)
Charging plate
This notification pops up every time I put the Note on the charger. I'd like to get rid of this notification but I don't know how... No big deal, though.
Also another thing is, keeping the screen on while charging option doesn't work with wireless charging and this really bugs.. I guess I'll have to do some search to do this.
Anyway just wanted to show off..
looks great, i have the same charging pad, let me try diy a dock station with that like u!
Also I downloaded Tasker to keep screen on while charging. Works like a charm!

You know what.. I thought I was posting a forum specific to Verizon Note II...
How long does it take to fully charge?
Hi there, thought i might post another little Mod that came into my mind
We all know that the Xperia-Z ist not quite an endurance runner when it comes to Battery-Life and i guess most here will most-likely have a power-bank with them, just in case.
Problem with that is, the o-rings are prone to damage due to opening the flaps all over again.
This is most-likely also a main-reason for water-damaged devices, you know it, i know it, and Sony knows that too.
So lets see what we can do to that dockingstation, so that we get a mobile Power-bank Dock.
Its actually plain simple, you simply get yourself a so called "EasyAcc 3000mah U-Bright"-Powerbank, this Powerbank fits easily centered unto the Back of the Dockingstation without being distinguishable looking at it from the front side, and if you dont know the Dockingstation even sideways.
The Dimensions:
Topside of the Sony Dock : 14,4cm x 3cm
Easyacc 3000mah U-Bright : 10,7cm x 2,2cm
A picture of the Easyacc:

which would basically go behind the XperiaZ, and look like this Illustration:
The way you fix it in place would be really up to you, probably glued, or by using neodym-magnets, or probably even some Velcro or zip-ties.
Other than that you just really need a really short usb/-to/microusb-cable that goes from the Power-bank to the Micro-USB-Port
Hope this probably is useful for one or another!
Thanks.
That's actually not a bad idea!

Does anyone know what the voltage/current specs of the dock that connects via the 2 connections on the left side?
Do you mean polarity or really only the specs e.g. Voltage/Amps? The dock itself has an output of 5V/1,8A which is kinda funny as the default Sony-charger is rated 5V/1,5A
The mentioned Easyacc Powerbank outputs up to 5V/2,1A without (verified) getting hot.
Hope this might help

If you are holding your phone horizontal with the connectors facing down (like you would put it in the dock), well then:
LEFT-> POSITIV
RIGHT-> Is negative.
Its actually even marked on the Dockingstation itself, in case you have the Dockingstation

Nice!
I had something similiar for my SGS3 but was missing something alike for the Xperia-Z.
Well i now did the modification mentioned above and iam good actually
Eventually get a power-case later on, although i kinda like the Xperia-Z as it is (thin as hell )
Thank you anyways for mentioning it, probably a better alternative to other Users
