I have an hd 2 and its a used one when i bought it. So i dont get the original charger. I got a samsung charger @ 5v, 700ma. But when i connect it, the phone shows usb detected. Though its charging, its pretty slow, i think the usb mode makes it. Taking only few 100-300ma only. And the charging takes long. I know htc need 1amp charger. But i cant get it here. So i decided to rip the charger and make some modifications ( like grounding or shorting the data pins- the middle two) . So i need a little help. Any of you guys having an htc original charger pls help me. Howz the data pins connected in the original charger? Are they shorted together or they are open? Or they are grounded? Pls help me those who know abot it. I want to make my charger form usb charging to default charging. It badly needed

That's weird. I've got original Samsung 0.7A charger here and HTC Desire HD does detect it as charger aswell and takes 1A from it. Shortening datapins together does usually convince most of phones that they are connected to wall charger. Maybe it's not the case for HD2.
Samsung Galaxy Phone Rapid Charger Modcheck this thread few under yours... speaking of shorting data pins.
HD2 is same as most, requires 2 data pins to be shorted together (2 inner pins).
Easy mod on most charger units. If charger is a cheap china job, the quoted 700mA figure could be optimistic ... temporary mod it by shorting data pins together & see how it performs ...
But there are 3 pins and not 4. So which ones are the middle?

can anyone confirm if it worked for them? I made an adapter by shorting both data leads, but it didn't work for me. My phone will charge when switched off, but when it's on with both gps and data running, it barely gets enough current to charge the battery. Only my original cable works.

What device?
Signalling a dumb charger with MiniUSB (as opposed to MicroUSB) is less standardized. On most MiniUSB devices it's done by shorting pin 4 to pin 5, but it varies.
I could be wrong about this (someone please correct me if I am), but I believe the transformer inside the charger will need physically replacing if you're going to be pulling more current from it. If it's not too much over the charger's rated current it may be ok, but I've burned up more than one of them by hooking it up to something that draws more than what they were designed for.

Depends as part of the reason of the mod is to achieve full power draw of a acceptable rated charger by making the phone think it is connected to HTC charger & thus charge at mains rate of 1A or a little above rather than USB standard of 500mA. Most chargers of reasonable quality will supply 800mA to 1.2A & if you buy wisely a bit higher.
Issue arises on cheap china chargers with false specs that actually only handle 500mA & perhaps 800mA max for short bursts but when these are forced to supply more will fail.
A good quality charger will have no problem supplying full charge to a HTC handset ...
A good example - getting a non-iDevice to pull its full rated charge current from an iPad charger (charger rated 2.1A, but nothing but iDevices will pull any more than 500 mA from it without modifications.)
A good example of cheap Chinese chargers - the "1A" chargers carried by Monoprice. They're good for 300-400 mA at best. You won't burn them out as it's a fundamental current limit setting of the SMPS chip, but the voltage will droop if you try to pull too much out of it. It's the only Monoprice product I've ever been disappointed with.

sorry about that, I have the HD2. if I use the replacement cable with both data lines I shorted, it never charges when the phone is running. but if I swap my original cable the phone charges normally.
it's as though it ignores the shorted data lines, or maybe the HD2 doesn't really work that way?
I'm worried because my original cable is beginning to show signs of wear and tear.

There have been quite a few postings here on people having problems charging their XDA with thrird-party chargers originally built for the XDA I.
Add me to the list I"m on the road and can't get the damned thing charged using the charger.
However the good news is, that the problem is not the cable (or the connector for that matter). Right now I'm in the internet cafe using the USB-connection to charge the XDA II at least a little. THis is working!!
My third-partz charger is a power supply with a USB-socket, that connects with this charge-sync cable. But, its not working! This leaves two possibilities:
1) The power supply is providing a lower voltage than the XDA II requires (something less than 5.0 Volts, mazbe 4.7?). I can't check this here, but if someone with a similar problem could measure his charger voltage using a multimeter, we might find an answer. Pins to check on this site under "connector".
If this is the cause, it won't help me here, but at least we'll have the problem solved.
2) I noticed in my charger, that the USB/pins 2 and 3 ( Data-H and Data-L) are unconnected. Potentially the XDA II has an issue if these lines are floating whilst power is applied to the USB-bus. I don't know if we can check this easilz,bu if someone has an Idea?
Greetings from the Maldives 8) Sun, warm, great, but no power for my XDA!!!

I'm using a nokia charger, and the supplied adapter and it seesm to work fine.
MDA/XDA II Pinout - Charge Issue Resolved!!
Being back from my vacation, I immediately got into figuring out why my third party charger was not working, though the MDA II would charge through the same cable when connected to the USB-bus of a PC.
It was a wiring error in the USB-cable after all!
To figure it out I took that little adapter that comes with the original charger apart. Though the MDA/XDA II has the same pinout as the MDA/XDA I, there is a major difference in that not all GND pins are connected together inside. In order to charge, at least one of Pins 16,17,18 must be connected to ground. The grounds on pins 2 and 5 are not connected to the internal charge circuit. TO make things worse, the MDA/XDA detects an external charge power source when pin 2 is GND and Pin 22 is +5V - so the light goes on, but it still does not charge.
On my cable the USB-shield was connected to pin 18. When connected to a PC, the shield was connected at that end to Ground and all went well. On my charger supply, the shield was not connected, so it couldn't charge.
I just rewired the connector and see there it works!
So, if you have the same problem, and are handy at the soldering iron, there is a solution! For those making/selling those USB charge/sync cables, get it right the first time!
Is it safe using a Nokia Charger ?
My Nokia travel charger is rated at 6.2 V, not 5.0 as the one supplied with the XDA II
Regards
Michael
Yeah! But watch out anyway because the volatge is not the only thing to check before charging a device. The right voltage but a bad amperage can cause lots of damage...
Using the Brando USB charger woukd actually DRAIN the battery when the bar reaches yellow....
Using a Nokia charger
The Nokia is rated at 6.2 V 720 mA, the original charger is 5V 1 A.
If I understand my physics right, the XDA may draw more current that the charger can handle, so AMP vise, the danger is on the charger ?
Not that I belive that the XDA would really pull 1A, but you never know.
It would be really nice to have just one charger in the travel bag..

This was the effect I had. Its a mistake in the wiring on your cable.
Thanks,
What I am really after is to find out if there is a place to find a USB cable that will work right out of the box/dodgy package that it comes in. I am not good with soldering irons or electronics and would like to buy one that is wired up correctly to charge my XDA II.
Cheers.
Anyone seen where to buy extra power adapters? Be nice to have one with a longer cable. Stock one is very short.

I couldn't stand it anymore so I snipped my wire and added another 4 ft.
I have been trying to get an additional PSU and car charger for my Acer. Went to Frys, tried almost EVERYTHING they have on those Universal PSU and NONE of them work in the pin connector for the Acer. What gives!
Try to get a free tip for my Energizer Xpal and also result in zero search. Any fellows have a pointer to where in getting the right tip? Thx
So far the ONLY one that I have found that works is the Enercell 12 / 1.5 with the 'G' tip, but it's like $30 at RadioShack. The tip itself is a little long and if it wiggles it will stop/start charging off and on.
I'm working with a few people to find some at decent price for us.
anyone measured the dimensions of the charging tip at all? If worse comes to worse we could always buy a generic 12v 1.5a AC adapter from ebay and buy the tip separately to solder on.
The USB port wont be able to charge the tablet fast enough and the battery will still drain. I've found that this happens on my Xperia X10 mobile phone. I have to disable 3G data in order get it to start charging.

The 'g' tip for the Encercell is 1.1mm x 3.0mm
Hope that helps
thanks for hte dimensions... unfortunately they don't sell that brand over here in Australia. I'm also reluctant to pay ~$30 for a charger.
I wonder if one of the round tips on this USB charger would fit:

It may still charge if the device is switched off completely.

No charging difference at all except I don't have to have my face mashed up against the wall while it charges.
I used a piece of wire from an old 1amp charger I had. The extra piece doesn't even get slighty warm. 1.5 amps isn't all that much juice. I did solder the connetions too.
huh and it is only $10 for a new one.

Wal-Mart Car Charger
The Wal-Mart Car charger for portable DVD players works perfect.
a quick look at the wall power supply says that it it needs 12V at 1.5 amps with center of tip positive.
The Wal-Mart car charger puts out 2000ma (2amps), and has a tip that works.. It works PERFECT and it only costs 15 bux.
usb charging is out.. usb is only 5V at 500 ma (.5 amp).. not sure why everybody complains about wanting USB to charge their tablet. Even if they did add it, it would take so terribly long to charge it, you would get mad. With the proper charger and voltage, it only takes about 2-3 hours to fully charge the thing...
Good luck!

This has been a topic of discussions for a LONG time hopefully you'll know.... Couldn't there be a potential issue with charging at 2 amps when it calls for 1.5?? I was told you could use less but not ore without causing damage to the battery?
I have a 'demo' on the way from overseas to try that I should get Wednesday. I will let you know ASAP.
This is a big issue with me as I prefer a charger at home and the office and I'd like something that I can charge on my desk 'without my face mashed up against the wall' (as atomicwedgie so perfectly put it)

The Amp rating on wall chargers is what the charger is CAPABLE of outputting, not what it is always outputting. As long as there is current limiting built into the charging circuit (which is a must), then the charging circuit in the A500 won't pull any more amperage than it needs to charge. Don't worry about buying a higher amperage charger than is needed, but do worry about buying one that is lower as it can overload the charger.

Apologies if I don’t have the right forum lads,
I bought a Pipo Max M1 tablet about 3 months ago. I loved it , a very good tablet.
I bought a second one for my nephew as a Xmas present.
Before I gave it to him I charged it using my own charger a 5V, 2.5mA charger.
Then I took it to him in Greece.
Now when I went to Greece I never took my charger with me, I assume my nephews charger would do just fine.
When both tablets were discharged I used my newphews charger. This charger was a 12V, 1.5mA charger totally different from the one which came with my tablet.
When I used the 12V, 1.5mA the tablets showed both 100% charge in 2-3 minutes and then both discharged in less than 1 minute, clearly something wrong with that charger. Both tablets never charged again and where completely drained.
Now when I came back to the UK and used my charger (which was working from the start) , my tablet will not charge, it will not turn on and the tablet will get really hot when the jack plug is located when I hook it up to the power supply.
Is it possible the tablet is fried because of the wrong charger that came with the second tablet?
Could it be a matter of taking it to a technician and fixing it?
Any ideas guys?
Thanks in advance and looking forward to your reply
I have the same problem with you. They sent me the wrong charger (9V, 2.5A). The tablet was dead after 3 minutes. Now i'm waiting to receive the right charger.

Panospc I have tried the reset button quite a few times but the batteries are completely drained!
Also I tried the method outlined in your link , although i had to cut the red cable and reconnect it but nothing happened.
My worry is that the tablet now overheats where the power supply plugs in.
Did your tablet overheat when plugged into the power supply without charging or turning on? Does it work now?

I have only the 9V 2.5A charger right now, with this charger, both tablet and charger was cold all the time after 4 hours of charging. The tablet is not turning on. When I get the 5V, 2.5A charger I will inform you.
If you have a multimeter, try to measure the voltage of the battery, maybe the voltage is higher or lower than normal.

Yes I had the same issue when I was trying to get different adapters to work with the tablet.
I have ordered two seperate adapters from ebay both at 5V,2000 mA which the seller described specifically for the M1. I will post them to Greece and hopefully they will work.
Regarding my tablet as I am no expert, is it possible you think my tablet was fried?Can it come back to life?
A highest voltage adapter than 5V (the 12 V that I used) , do you think it burned the unit?

I got a 5V, 2A charger from ebay and my tablet works fine now.
I guess that the tablet has a circuit before the battery that prevents charging if the voltage is higher than 5v. So I think that this circuit was fried from the 12V charger and the current doesn't reach the battery and other parts of the tablet. You have to find a way to connect the tablet to an external charged battery with the same voltage to see if the tablet is alive, I think most mobile phones have a 3.7V battery also.

Hi guys I've got the same problem. I got my PIPO m1, but it didn't switch on with or without charger. I disassembled device and charched battery straight. So, after 8 hours of charching it has just 3.25 volt. And if I connect charger to the unit, voltage on its motherboard is 0.5 volt (battery is desoldered at this moment). It can't be the problem of charger, cause I used several ones (5V, 2.5A).
And! The main point! Stock charger was from PIPO m2 so it has 9V Unfortunately, I noticed it after my first charching tryings.
For now I've got a brick. Have you got any ideas what i can do to reanimate it?? ( Thanks!

SpookyXDA I will follow panos advise today and try to connect the tablet straight to an external 3.7v battery.
Also I will try and find a 3.7v charger and connect the battery straight to that charger and see how it goes!
I have the feeling the circuit board , like panos said above, was fried at a point due to the 12V (in my case and I think the same for you since you used a 9V). If anyone is here has good imagination and creativity on how to overcome and bypass the fried portion on the circuit that would be great!

If it is impossible to fix, I am interested to buy it because I'm looking for some spare parts.
My phone only goes into charging mode when I plug it in to my computer. Anyone have this problem?

Have not had this problem myself. Try another USB charger? Just about anything that's 500mA will work (albeit not nearly as fast as the 2.0 amp charger that came with your phone).
I suspect your charger.

It was the cable. I really didn't suspect it would be that since I have barely used it and I've only had it for two weeks. Thanks!

Good to hear it was a simple solution. You might check with the place you purchased it from to see if they will provide a new cable. I guess we can just be glad you didn't find out about the cable during the middle of an Odin flash...

No kidding. That would hurt a little
I am now having this problem after my phone got wet. No AC or DC chargers will work but the phone will always charge from a computer or even the USB interface of a car.
Even if I can get an AC or DC charger to be recognized, the phone will show as charging but the battery will continue to decline.
It is making no sense to me though I assume getting the phone wet partially fried something.
Yeah the voltage is increased to charge you battery when on AC power, at the kernel level. USB voltage is lower. So i'd say surely fried, and will no doubt stop working sooner or later.
I know that on my s2 I had an issue where it would say its charging and when I woke up in the morning no charge at all. The pin/row of pins or bar if you will would bend down and not make good contact. I used a tooth pick to pry up on it every time it did that.

Thanks. I didn't realize that the charging port was removable on the S4 so I swapped that out and all is fine now. :good:
Ummm... No its not the voltage. It is the ID pin. The voltage stays the same. The only actual difference is the milliamp mAH output of the charger. A normal USB plug has 500mA our charger has 2000. How the phone tells the difference? The 2 data pins inside he charger are shorted together. The voltage always stays the same.

Little help chaps.
Ok i've just bought this http://www.ebay.co.uk/itm/390566738301
I presumed (not sure if rightly or wrongly) that it would be sufficient to charge my Nexus 4
I'm using an older usb cable I've got to charge it in my car however if i'm using navigation then the battery still decreases.
I've got a funny feeling that the cable is the culprit but i'm not 100% sure.
Is there anyway to monitor how much juice your phone is getting from the charge?
P.S in the battery monitor screen it says AC not USB
Thanks in advance for any help

Battery monitor widget pro. It monitors the mA that's being used, mV, etc. Maybe the phone is pulling more mA than the charger is supplying.
You need to go into your battery settings/status while your phone is plugged into your car charger.
It will show one of two statuses:
Charging(AC) and Charching(USB)
If it is showing charging(USB), then the phone is detecting a false data connection. This can be solved by taking apart your USB charger and soldering the middle two pins of the USB. These pins are the Data(+) and Data(-) pins. I attached an image of the two Data pins soldered together on the usb charger.
If it is showing Charging(AC), then your USB charger is not pushing enough mA to charge your phone. Most cheap car USB chargers are in the 500 mA to 700 mA range. The stock USB wall charger that comes with your Nexus 4 is 5V 1200mA.

Yeah it definitely shows AC was the first thing I checked, so what your saying is that link o posted above is actaully a false claim to how much power it knocks out?

Hard to say. From my experience, you get what you pay for. A USB charger that cost less than 2 GBP seems unlikely to support the kind of mA throughput that the Nexus 4 requires.
Some ways to check this are to check the power supply and draw through a battery monitoring app, use a different USB cable or the USB cable that came with your Nexus 4, or take apart the USB charger and inspect the hardware to see if it actually is built to support a 2A supply. That last one is a bit of a headache.
Here is an iFixit teardown of a similar USB charger which goes into detail about some of the working parts of a car USB charger.
To quote the final part of the iFixit teardown:
Quite simply, the device is a rebadged 500mA or 750mA USB charger at best. It is NOT 1A capable, despite what the sticker on the body says.

No problem! You should try and remember that the Nexus 4 is a pretty sophisticated piece of hardware. I'm not advocating that you go out and spend 20 GBP on equipment, but you don't want to use a cheap generic piece of trash to interface that electrical connection. The build quality of your charger can put your handset at risk to being damaged by electrical shorts and/or heat.
I would liken it to parking your sports car in a cheap parking garage on the bad side of town. Sure, you can do it, but there are risks involved!
