hello,
i hope someone can help me.
i need to know, wich contacts of the wall chager (mini usb side) are nessecery (e.g. + -) to chage my wizard?
History:
My original wall charger was broken (one wire inside the cable split up).
so i decided to soled an standart mini usb plug as an sparepart to the cable.
i messured it out, wich of the wire´s are the possitiv and wich one the negativ pole. so i soled each pole on the mini-usb port. it was confused because i messued that on the original plug the negative pole was on the shield and the possitive one one pin inside the plug.
but on the internet i found an description of the mini-usb plug wich means, that the negativ pole is also on an pin too.
with the negative pole on shield my wizard only charge on standby, and not in power off (if i pluged in on power off, the whole battery discharge until death !!!!!).
are there two negative poles?
can u help me?

Hello Friends,
i made myself a Carholder with Charger and Audio-Connection for my Wizard100. I took a Lm7805 to create +5V out from 12V of the Car Battery. I also took a normal Mini USB Plug, and connected the two wires who leads the Voltage to the unit with my 5V Regulator. When i turn on ignition in my car i could measure the 5Volts at the Cradle and when i plug in my Device the Charging LED goes Red and the Symbol in my Today Screen shows the charging. But when i pull out my Device after a while the batterypower goes down very fast and rapid. Why? Is there any conection that has to be done? How many pins are used to charge the Wizard by USB?
Charging current...
How much current is your rig capable of, the stock charger puts out 1 Amp. I know that the wizard is rather finicky 'bout its charging method. Hope this leads you in the right direction...as for pins, i would think that if it says its charging, then your pin outs are ok. It would most likely be about the amperage
The L7805 Regultaor IC fits up to 1.5A .Thats enough i suggest. Now i´ve ordered a real car charger and put the electronic in my carholder. What about grounding? Is ist allowed to put the Audio Ground together with the charging ground or must I divide both grounds?
Thanks so far for your replys...
hi guys, I soldered a 5v charger's +5v & ground wires to a female USB port, then connected to the mini-usb port of the Atom, external power was detected but it doesn't charge, what else do I have to do to trigger charging? thanks!

Interesting. I've noted similar issues, I first thought it was to do with the power current capacity however I'm not so sure now. What I did find was that if I plugged in the usb plug first and then turned the charger power on (e.g. car charger 850mA) then it would charge. However the original charger worked any which way. Also turning off the screen would result in slow charging even when it said not! Does this help?
There is some problem in oem battry driver, you can google to find the driver hotfix.
sorry for my BAD english..
You must give two other pins short with resistor as i remember. This is in order to simulate USB connectivity, which original charger do.
This is for HP Ipaq rw6815 I have..
more info you can find in below links it's for other devices, but the workaround is the same:

I don't think below method i safe enough, I think it's not a wise decision to shorten your data pins, but obviously work with iphone

hi there.
shortly-i have this phone with no orig. usb cable and with no wall charger. it was friend of mine phone actualy. given to me with dead battery (i am not sure but i have trouwn it away long time ago)
first I did was to wait until friends of mine from china had sent to me 2 batteries compitable with the phone. what i discovered is that a normal ordinar usb cable cant charge the phone's battery it only can connect to the pc.
second what i did is this: i found my old charger from a very old panasonic cell phone and had a try to make the charging process with the simply contacting corresponding pinouts of the battery to the +&- of this same charger (somehow i dissasembled the plug of that charger and it became more "comfortable" to get in touch to the pinouts of the specific cingular's battery)
that unordinar way i did discovered that i can charge these batteries even not sure how much appropriate that other brand wall charger is. It seems its pretty much the same as a power characteristics.
Meanwhile (as i dont use this phone) i had some free time to search the net and to have better idea about that strange unordinar power charging matter with that model of a phone. The situation is that i cant find a place nearby me to buy a cheap usb and wall charger and become using this nice device finaly.
And also i dont want to buy these cable things before clearly understand why this happens ..
I did try also to charge this phone with a HTC brand wall charger but no sucsess again cause it seems this wall charger is for other htc phone (even same mini usb plug and same characteristics)
What i need is to have answers by someone very informed about that matter and let me know what exactly is the specific power charging matter (need explanations i mean) with this phone. If sharing some good ideas about how to remake others usb cable or wall charger for geting it work along for me in such a case , i will appreciate this very much
thanks
charge
hi ! please forgive me for my bad english! in this case you can charge your phone in 1 way! you need to procure a motorola or any charger with same socket but attention the charger must have 6 volts and no less than 500 mAh(milli amps)! you cut the wires and one wire put on the + of the battery you will see the signs on the battery an one wire at the - no matter which one. and you need stay with the wires 3 - 4 minutes on the battery ! then you put the battery on the phone it will start and then you cand fully charge it with the usb cable ! good luckk ! i hope my inf will help you!
no
no it doesnt work that way.
what i need is the simple answer : what is so special into the pinouts of htc cingular 8125 wall charger?
thats what i need only. Then I might figure out how to proceed
Thanks anyway
I don't know if anyone else has had trouble doing what I have done, but I've got the Cingular 8125 (HTC Wizard 100), which is also known as the HTC 8125.
1. I bought a car charger at a convenience store for $6 that had the mini-USB plug. It worked like a charm. Never any problem there.
2. I also bought a standard USB to mini-USB cable from the local computer store, because I had lost mine, and it also worked fine for both synchronization and for charging.
3. I bought a second wall charger, buying a standard mini-USB wall charger sold pretty much everywhere cellular phone chargers are sold. It's a common charging port, and this generic worked for me as well.
I'd be interested to hear if anyone has had problems with these types of devices not properly charging the unit.
Even my USB cable for my portable USB hard drive will power my unit.
EDIT: About your problem with it not charging. I had that problem about a year ago, when my battery got extremely old. It wouldn't charge even with the original charger. I just needed a new battery. The batteries get old and stop taking a charge after a certain amount of use. How long this takes depends on how heavily the batteries are used. They, like car batteries, do not last forever.
I had this problem when I had my wiz too. The battery died and drained, and my phone refused to charge it. I took it to an AT&T service center, and they had no clue what the problem was, and they wanted to issue me a replacement (it was a G4, I had a G3, I wasn't about to fiddle with that at the time.) So I asked to borrow a demo device they had there to fix it. I charged my battery on their demo device no problem, got it up to 3%, and finished charging it through my USB cable in the car socket.
It appears to be a sort of one-in-every-few-or-so type condition, but I got hit with it.
seems like noone can tell me if something special inside the mini-USB plug.
i realy cant charge. Very nice device, but i cant make it charging up whit cables.
guys, from up there, say that nothing special about the charging cables, but i trust what i see not what i read.
Perhaps there is a problem with your USB port on the device? USB charging has standards, and all devices that need power from a USB port have the same power pin configuration. Otherwise, they can't call it a USB connection. It would have to be called a proprietary connection, and they would have to change the plug size/dimensions and pins.
If there isn't a problem with your battery (which is the most likely source of your problem), then it may be a loose connection on your USB connector. This happens with a number of devices.
If a sync cable connects to the PC but will not charge the battery, then you definitely have an unusual pin detachment of some sort, or a bad battery.
thanks again..
for pity i was writing a lot to make my recent post and finaly it desapeared cause my session was left.. its funny in some case, but now i just dont want to repeat all what was intended to be posted
i give only the link where you might see why i was assuming that this is a kind of a special matter here with that htc 8125 charging

so, any more help will be appreciated a lot
thanks
SOLVED: HTC Wizard (Cingular 8125) Dead Battery Wont Charge

Hi - Too bad for the OP that asked questions but did not listen to this brilliant post.
I have confirmed that a variation of this method works perfectly! I have an old Cingular 8125 that I have been trying to charge for over a year using various USB chargers and NONE would charge the device.
The reason that this may happen is that the original charger has an output of 1 full amp which is much higher than most chargers. The voltage is the same but you need a charger that can handle such a strong current draw.
Nearly all USB chargers can only handle around 250milliamps - 500milliamps which is about half the power needed to breathe life into a fully discharged battery.
The best solution is to NEVER let the battery fully discharge.
Here are the details of what I did:
1. Find the best match charger of 5-6 DC Volts and ability to put out as close to one amp (1000mA) as possible. I chose an old Sanyo SCP-07ADT that is rated at DC 5.4V at 800mA. The plug can be any type, no need to be USB.
2. Cut the connector off the end of the cable and strip the outer black part up about an inch and then strip the positive and negative (red / black respectively) wires up about a millimeter, just enough to have bare metal ends to touch to a small area.
3. Take your battery out of the phone, look at the back of battery for the + and - marks which correlate to one of the metal connection points on your battery, this is where you will "touch" or "attach" the bare ends of the wires.
4. Plug the charger in making sure not to short your bare leads. Before you do this double check that the OUTPUT of your charger is indeed DC voltage so that you don't hurt yourself. You do not want AC output and it can be dangerous.
Then touch the bare end of the red wire to positive of battery, and black wire to negative terminal of your battery. I held them with my fingers while surfing the web for about five or ten minutes. I had no idea if anything was happening or not but it "felt" like the battery might have gotten just a bit warmer.
5. Unplug the home-made bare wire charger and put battery in your phone. Quickly attach a USB charger or just plug into a USB cable of your computer. I pushed it in and nothing happened at first but finally I heard the standard "bleep" when you plug a USB device in. I knew that I made progress because it never beeped before it took about 30 seconds and several "bleeps" of connecting/disconnecting from USB but eventually the charge light stayed on!
It's been about 30 minutes and I'm up to about 50% charge and been using the phone heavily while charging.
So, in summary... never let your battery discharge below 5% or you can only charge it with an OEM cable rated at 1amp (rare). IF you let it discharge to "dead" then charge for 5-10 minutes with the "wire" method and then charge normally!
Thanks to Dozzen for the original idea!!
Wizard that won't charge
When my Wizard/HTC 8125 goes dead my cure for the battery is to use a 9 volt charger with the wires stripped back also. But, my method is a bit different. I place a standard Christmas Tree light bulb (the newer small ones)in series with the charger wires. Observe the correct polarity. The battery is labeled + and - so that part is easy. By using the small light bulb you are doing 2 things. 1.You can see the slight glow from the bulb and know that proper connection is made. 2. You are limiting the charging current to the battery.
If you get really creative like I did you can solder a couple of small nails or in my case a set of red and black probes to the setup and the points on these nails/probes make for much easier connections. Note.... This method may take a few minutes longer but, is much easier on the battery.
In my experience once the battery is below a certain level NO charger that I plug in will work. I just purchased a used 8125 from eBay and brought it back to life most successfully with this method.
hy there my htc wizard battery whos dead so i charched with a cable with + and - the phone starts but when i try to connect to a usb or a adaptor it doesnt charge anymore it show me the charge icon on the baterry but it doesnt charge the usb works fine it's sync to my pc but it doesnt charge anymore... what sould i do?
So it seems no one touched on what really matters here.
A design flaw, in my opinion. The HTC Wizard cannot recharge via USB unless there is enough power to turn on. The reason is because it requires the OS to charge.
So, what many people already posted are very creative ways to charge your 8125. The easiest and cheapest way, in my opinion, is to use AA batteries.
1) Take two AA batteries and tape together so they are in series. Imagine it like this... [- AA battery #1 +][- AA battery #2 +]
2) Use two wires and tape one to each side of the AA's (one on the + side and another on the other battery's - side since the - of the first battery is connected to the + of the second).
--w-i-r-e--[- AA battery #1 +][- AA battery #2 +]--w-i-r-e--
3) Connect the positive (+) wire to the positive (+) side of the phone. By this I mean the 6 metal pieces that stick out to contact the phone battery. I did it by wrapping the wire around the top most one (or second top most, it's been over a year since I've done this.).
4) Connect the negative (-) wire to the negative (-) side of the phone. Again, bottom most or second bottom most (see #3).
5) Insert phone battery while the wires are still in and connected to the two AAs.
6) Let the power flow for 30 seconds or so and then try turning your phone on. This part is the important part because you cannot use a USB to mini-USB connected to your computer to charge the phone unless the operating system can function. Meaning, it needs to be turned on first.
7) Once the phone is on, plug in the mini-USB part and connect it to a computer. I'd recommend getting at least 5% battery before disconnecting the AAs, seeing as you need to be able to start up your phone long enough for the OS to boot. Once the OS boots, you can fully charge it through a normal USB to mini-USB connection on any computer.
old post but just wanted to say thanks. Used the wire to battery method and got phone turned on after 2 mins of holding wires to battery.
I was always wondering how to speed up this unacceptably slow USB charging (If you are in a low signal area with bluetooth ON then the battery is drained far more quicker than the laptop can charge it ending up with a flat battery ). Finally I tested the output from the pins of the wall charger and my Laptop. Even when the laptop is powered off (no data exchange) the USB charging is very slow. The HD seems to send a ~1v pulse through D+ channel when to connect it to USB port (even when powered off the device seems to check if it is a USB data port), but with the charger it does not!, so we need to break this communication.
So I put a thin plastic film over the D+ and D- terminals of the USB cable and voila the device charges much faster..(slightly slower than wall charger - 25% slower, can be accounted for by the lower power output of the laptop USB port, the voltage of laptop usb port is 150-200 mV lower).
While I am typing this my HD has gained 9% charge with screen on!! . Natively it charged atmost 1% by this time with screen off.
Now I am looking for a permanent mod for my spare USB cable hacking off the data lines.
For those in a hurry with nothing but a HD with flat battery USB cable and a computer at hand, worthwhile using a thin paper over the inner two pins of the USB cable on PC side and plugging it in. (You do this at your own risk).
Hope it helps others too. Let me know your experiences.
With my Desktop USB port, charge rate is better than wall charger if you block the data pins. The port seems to be capable of 1.5 amp at 4.96 v
Also ensure that the USB cable snugly fits the mini USB port on HD.
Could this be also the problem why (my) Blackstone doesn't receive a TMC-signal with HyperGPS & iGO8 while charging in my car?
It's a genuine car charger from HTC, so I should say these pins are already "shut" from connection, or am I wrong?
I have a usb cable that is dedicatet for charging. It dosent have D+/- wires. With this cable on my laptop the charge time form about 20% is more than half of regular USD cable..
The cable was supplied with a car BT handsfree.
Regarding the TMC issue Im not shure, Try asking the guys that developed HyperGPS they might know, if not they might be able to fix if they arent aware of the issue
Interesting tip, thanks... I've lost my charger and have been finding it a pain to charge it using the USB port on my laptop.
I cut a small strip of paper from one end of a sticky note, and stuck the adhesive end to the outer flat surface of the USB plug to secure the strip in place. Seems to have done the trick, because the charging light is on and the PC hasn't detected the device. As for how long it takes to charge... will have to wait and see.
Also, I was wondering if there was any difference in charging speed (i.e. when charging via USB normally without using this trick) between activesync and file transfer mode?
Hello, I've just bought an emergency charger for my Kaiser. It takes the power from an AA battery and gives the USB voltage in the output. It works great with my Mio A 501, but doesn't work at all with the Kaiser. I did a quick search and found this in a discussion about car chargers:
Are you using the HTC charger or an OEM one?
The HTC charger works all the time the OEM ones don't - the reason being that if you use a normal Mini USB cable, the handsets will only take a charge if there is an indication of a data connection (either than gprs or the cable) - otherwise it won't take a charge.
You can apparently solder a couple of wires together on a normal mini USB cable - but I wouldn't know where to start on that!

Now I've already heard of that, for example, a Play Station Portable needs the data wires in the USB grounded in order to charge. Is it the same with Kaiser? (putting three wires together isn't a big deal) Or is there an easier way how to make it charge?
So, I gave it a try and soldered the data wires with the ground wire. But when I try to charge the Kaiser, a yellow led starts to glow (which it didn't with the original cable) and, after a minute or two, the led goes off and Kaiser stops charging. When I turn the Kaiser off and then plug the cable in, the yellow led doesn't go off. However, when I turn Kaiser back on to check the battery meter (after about half an hour), I find out that the battery didn't take any charge at all. So, could anyone tell me what the problem is?
thanks, Mike
PS.: Adding some photos of the wires...
Probably because of the voltage...
Hey!
Have you checked the output voltage of this charger? Standard charger outputs 5V. If yours outputs less - the battery won't charge; if outputs more - you may "burn" your PDA chipsets
5V - 5.5V is safe range.
I found this on thinkgeek.
http://www.thinkgeek.com/gadgets/cellphone/b43f/
It says for iPhone, but sure it would work just fine with other devices that have issues.
had a same problem but using it in the car...
when i got my tytn2 i immediately bought a car charger and the salesman told it's an original one, said output 5v 1A.. when using in the car it charged for a minute or two and went off... than i got from ebay a micro usb 1A charger (used for iPhone too) and tried in the car-> it work flawlessly
