Kaiser/Universal mini usb

Before i got HTC Tytn2 i had qtek9000. I had also Brodit car holder and instalation in car with cool hidden cable for charging qtek. After i bought Kaiser i also bought Brodit holder for Kaiser. I thought that this miniUSB should charge battery but it is very strange. Kaiser shows "charging" but battery is not charging. On normal 220v original Kaiser charger it works like charm. Are pin combinationfor these two smartphones different?

As far as I know the pinouts are the same.
There is a blog here which describes the HTC ExtUSB socket and also mentions that there are 2 charging modes. The faster charging, higher curent, needs 2 pins to be jumpered. Without this fast charge the current is limited and may not be sufficient to actually charge the device if you are actively using it. eg. GPS, 3g, Music etc. Try using the charger with the Kaiser in GPRS only mode, or Radio off, and with no apps running, this will enable you to see if in fact it is charging but at the slower rate. The Kaiser may need more power than your Qtek needed.

do you maybe know which two pins?

Quoting from the blog...
As for the power pins question this is simple a case of juice.
If I plug the USB cable into a HTC device, then plug that usb cable into a usb port and just wire that up to a bench power supply... the device draws a few hundred milliamps. (As much as USB spec allows).
This device, much like other mobile devices I have used which USB charge, can barely draw enough power of the USB to run itself let alone charge the battery.
However, if you close the A/B pins you are telling the phone "This is not a USB port, its a 1A power brick" so the phone charges the battery at its maximum safe rate.
This behaviour is stop the phone frying your usb ports.

Hope this helps

I had problems with some cables and some car chargers. It turns out that when I use a cable for sync that is fully USB 2.0 compatible everything works. For charging in my car I bought a universal car 12v to USB converter. Then I am usinging the same USB 2.0 sync cable with it. It works.

When i first got my kaiser, i used the car-charger from my old MiO A701. For a period of 1,5 month, it worked just fine. After that, for some reason, kaiser shows that is charging but it really does not!
I thought it would be a charger malfunction, but after reading the posts above i have my doubts...

Problem charging

One of my Tilts suddenly won't charge on some chargers:
HTC AC charger - OK
USB to PC - charge and sync OK
HTC compatible car charger - no charge
Blackberry AC charger - no charge
My second Tilt is OK on all four chargers (as expected).
I am suspecting a problem with the usb connector but looking for a reason why some chargers work and others don't.
Any insights would be appreciated.
Thanks

I saw a few weeks back a thread on this very forum that examines this problem in detail -- keep searching

Problem Charging
I think I 've read everything relevant. I am looking for someone who has h/w insight into the Kaiser charging scenarios. I suspect mini-usb damage.
I am somewhat familiar with HTC's pin 4-5 implementation to detect a true charger as opposed to a usb connection that can also apply power.
I want to eliminate software possibilities.
How can a Kaiser charge from an HTC AC charger and also charge from a USB connection to a PC....but not recognize a car charger or a third party AC charger that does not implememt the pin 4-5 grounding technique to identify a charger (and not a generic USB connection).
That is where I am lost.
Looking for "inside-out" knowledge...not "outside-in", if you catch my drift.

charging problems
If the car charger worked before, you can do an easy test. Just put in the car charger and do a soft reset. If it starts charging than, its only a software issue. I did a modification on a charger myself. Because I have different chargers using a normal USB cable, my device didn't charge alway as well. I modified a standard miniUSB cable by connecting the 5th pin to ground. When I use this cable for charging I never have a problem anymore. Succes.

I had exactly the same problem after I tried to re-set my device by poking the stylus in the mini-usb port instead of the re-set hole (tryng to do three things at once!). The port was mangled, and once i'd pushed it all back it wouldn't take a charge from the genric car charger. I bought an HTC branded car charger and it charges as good as a wall adapter.
I imagine that your suspicion of USB port damage is correct.

charging cable for X1

Can i use a non sony cable for charging my X1 or USB transfer? It looks the same as a USB mini connector that i have but i'm not game to test it without your advice?

Yes you can. The only comment to make is the number of connectors in the cable. Almost all cables will charge & allow you to connect with your PC, a minority may just allow charging.
(I once bought one of those roll-up cables from Boxwave, where the cable is collected in a disc: it was sold as a charging cable, and yes, it only charged! In the same box there was a synch cable of the same design, and that both charged and sync'ed)
And re the charger, you can use any. Charging from the PC is slower, as will be some wall chargers with a low rating (amperage).
But you will not damage the phone, however much power (amps) the charger promises to provide: the phone will only draw the current it needs.

Thanks for the reply. I'll test my cable.

x1 is miniUSB a universal std like a normal AC connector
even other htc devices with extUSB rather then normal miniUSB is direct compatible with
all miniUSB cables for charging and syncing with computers

[Q] Faster USB Charging?

Just reading up on USB chargers, and I found somewhere in a thread here about phones defaulting to smaller ma when charging via USB if the connector didn't have the data pins shorted or something.
So, I was wondering a couple of things:
1) If the default charger supplies 700ma, do you think that is the most the Nexus S can draw? Does anyone have one of these shorted USB chargers? Does it charge the NS faster?
2) If it does charge faster, how hard would it be to do something similar to shorting the data connections? I have a generic AC-USB cable which I currently use for my iPod touch.
3) Is there a way to check if it is already shorted out? The USB charging port looks similar to ones on my computer, but I'm not sure what to look for.
Thanks for any help! Maybe if we can sort out this stuff, we can provide a solution for those looking for faster charging!

it does work safely, i'm using a 1000 mAh charger at home, and a 2000 mAh charger in the car both are from aftermarket eBay/DealExtreme charges.
no overheating
and charges faster than stock

Ok thankyou for that AllGamer, I'll think of possible ways I could mod the charger now

The only reason it is slow is because of the USB charging brick instead of just a charger.

I know it's a wrong thread, but anyone has any pointers as to how to short a regular USB cable to make the phone think it's a power adapter cable?

Nah it's not the wrong thread that was one of my questions! I'm not sure exactly where you would do it, but maybe if you skinned the wire, then cut the data lines it would work?
Not sure which end you would do it on however, but that may not matter. Any other ideas?

The two center pins in the USB carry the data. If you pull them out, the cable won't be able to connect to the computer.

Wow - you don't need to do this and you wouldn't want to in a computer anyway.
The USB specification says that 500ma (@ 5v) of current should be available from a computer's USB port. Of course, the actual wires can carry much more than this, so manufacturers can tell their phones to takes as much current as is offered.
Almost all computers limit their USB power output accordingly - this is why some opld usb-powered external hard drives needed 2 USB plugs to get enough power. The only computers that I am SURE emit significantly more than 500ma on their USB ports are first and second generation MacBook Airs.
Some phones, the N1 and every other HTC specifically, look for a specially shorted cable to "know if they are plugged into the wall adaptor" as opposed to a computer USB port. In reality, this is just a way to make you specifically buy HTC chargers as opposed to third-party off-brands, because plugging one of these phones into an off brand charger will limit the current draw to about 450ma.
If you want to know if your Android phone thinks that it is in "USB" mode or in "AC" mode, just plug the phone in, open the dialer, enter *#*#4636#*#* and then select battery info. If your phone is one that cares (not all do), it will say USB if it thinks it should be in USB charging mode, or AC if it thinks it should be in AC charging mode.
I would not try shorting out the middle pins in a cable and then plugging it into the computer. First, most will probably just disable the USB port completely, shutting off even power you could draw. Second, if it doesn't shut down, you run the risk that a badly-built USB port might not properly limit the current to 500ma - and since they are not designed to furnish more current than that, you might melt something expensive or start a fire. third, if you make a mistake, you risk shorting out either your phone or your computer, which might ruin your day, week or month, depending on your financial means to replace the system that cooks itself.
I would just run out to your local store, pay 15 bucks for a 2A third-party usb charger brick, and go to town. That will work perfectly - this is what I use, and it probably cuts the charge time by 30-40%. Obviously, this indicates that the NS is not capable of drawing a full 2A - I have not put a meter on it, but I would bet that it limits itself to somewhere just under an amp in.

I have recently bought both a 2A wall charger and car charger and my phone does not recognise either of these as anything more than a 500mA source.
Is it really just a case of opening the car charger up and shorting out pins 2 & 3? they are currently not connected to anything in the charger.

If it's indeed a matter of shorting the data lines, then I think you can skin the wire as suggested by others, but then cut the data lines, short the end that leads to the phone, leave the end to the computer open. I think it's the phone that tries to determine whether the data lines are shorted.
Edit: Can someone measure the continuity between the data pins with the stock charger? I wonder if they are shorted. I'm still waiting for my Nexus S to arrive, so can't test it.

Yup, the data lines in the stock Nexus S charger ARE shorted.
I just modified a cheap 1A car charger by popping it open, soldering the 2 data lines together and putting it back.
The report on the Nexus S before I did this (*#*#4636#*#*) said "USB", and afterwards it now says "AC".
I will report back after I make a road trip if this improves the GPS + Pandora + Screen in car situation. I suspect it will.
----------------
Yup, the car charger seemed to actually maintain and increase the battery this time. Seems good.

The NS supports chargers output to a max of 1000mA, as it says on the back of it, where the battery resides.

usb cable defy+ different than normale ones

My defy+ cable has on the mirco side two metal pins on each side. Normale cables got only two metal pins on the wider side of the mirco side.

Sorry, I don't understand you, but you can use standard microusb wires for data and charge with your Defy+ (I usually use a Samsung usb wire)

The cables i used on my htc Desire wont charge or are only use full for date transfer. When i trie to charge true my charger or car charger. It start charging and within a second i got a message that it is unconnectend and then connected again. And it loops.

Those aren't "pins" in the sense of providing data signals or charging current. They are more like small springs designed to improve the mechanical retention of the micro USB plug in the socket. They don't make any difference to the electrical or electronic function of the USB cable, beyond reducing the risk of a poor physical connection, or a loss of physical connection if the handset is moved which charging/transferring data.
My Blackberry charger's micro USB plug doesn't have them , but the short USB to micro USB cable which came with my noise-cancelling headphones does - and the only function of that cable is to charge the battery in the headphones. I think you will find that there are a number of subtle mechanical variations of this kind between micro USB plugs from different manufacturers.

I used with my Defy+ usb chargers and usb cables from Samsung Wave and Blackberry 8990 and all of these works property for charging and for data transfers.
Maybe your HTC usb cable don´t work propertly?

Other possibilities are that the charger is faulty or providing a charge current which is slightly outside spec, or that there is a problem with the battery. I have seen problems caused by both of these kinds of fault (with third-party chargers and batteries) when using my Motorola USB cable.
