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...

Charging Tytn II with alternative USB Wall Charger

Can the Tytn II be charged with other USB wall chargers other than what comes with the package? I have 4 alternative wall chargers:
(1) USB wall charger for Blackberry 8707g
(2) TravelPac world travel adapter with USB charger
(3) USB wall charger for Aliph Jawbone
(4) USB wall charger for O2 Atom Life
I do charge the Tytn II through USB cable connected to my PC. However, I was reading somewhere that this is ill advised, as from a device longevity perspective it is always better to charge using AC Adaptor chargers as opposed charging through the PC, not sure how true it is. I do see under the “Power” settings that there is an option to turn “When device is turned on, do not charge the battery when connected to the PC”, so maybe there is some truth to it.
In any case, my biggest concern is with the wall charger for my Blackberry. The Blackberry seems to be using somewhat different voltage from other USB chargers as I am not able to charge the Blackberry with any other charger other than its own wall charger or through the PC. For example, charging the Blackberry through the TravelPac adaptor more often than not does not work.
Question is, can I (safely) charge my Tytn II with other USB wall chargers? Any downside from using non-HTC chargers? Thanks

Unless someone has already tried one of those other chargers and can post their success here, I would not try it - there have been reports of generic car-chargers and the like frying circuitry on the Kaiser, as the USB power connection is wired differently to some (superficially similar) devices. It's not really worth risking it, when I'm sure you can pick up a spare HTC charger for not much.
I charge from USB everyday at the office (and the mains, when I'm away from work for more than a couple of days) and after three months my battery performance seems much the same as everyone else reports - in fact, better than some. I know opinions differ on whether these modern batteries have any kind of "memory effect" or benefit from a proper discharge cycle etc - personally I've seen no evidence of that. In any case, absolute worst case scenario is buying a new battery some way down the line - given that there are already higher capacity aftermarket versions of the stock battery on sale, that might not even be a bad thing.
With my old Sony Ericsson M600i I used to find that USB charging would never bring the phone to full charge (however long I left it), and the 90-odd % charge it did have would never last quite as long as a proper mains charge. No sign of either issue on the Kaiser.

As long as the charger in question is rated at no more than 5v/1A (as the original Kaiser charger) it should be safe. The Kaiser can probably take more than 1A safely tho, but I won't guarantee that. That said, most wall-chargers are rated somewhere around 5v/1A.

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.

Using other chargers

Can I use chargers from other devices that also use mini USB such as my garmin GPS or will they damage my X1?

ive never actually used the charger that came with it(it came with the ugly European plug). if you are going to use a standard USB charger,dont go with one that has higher amps than the official one (i think its 700 miliamps if im not mistaken ) just to be sure
that said. i used the charger for the following devices to charge my x1 (some charge faster than others): Atom EXEC, samsung digital camera, htc wizard, motorolla dumbphone, usb pc cable, xbox360, g1

I charge mine via mini USB cable from PC, mains adaptors (2 different ones), 12V cig lighter adaptor.
BTW PC seems to be the slowest at charging.

Back to OP:
Yes, but it is not advisable. Check if the other charger has the same specs first.

USB is a standard isn't it? I don't think your at risk frying your XPERIA. If it managed 220 in Europe it will manage 110 here. As for me, I've charged my phone with everything, a USB cable connected to my computer, a car ciggarette charger that came with my Tomtom, and my friends iPhone charer. All worked flawlessly.

yes usb is std
it give 5volts dc
and charger which provide
5volts in the correct usb connector
can charge the device
nothing else matter
amps don't matter as long as it's more then 0.5

From my understanding, if the charger allows 1A, then that is the MAXIMUM it will provide, it won't be trying to supply that all the time.
So if the X1 wants, say, 0.6A, then a 1A charger will work. On the other hand, you wont want to use a 0.5A charger if it is trying to draw 0.6A or whatever higher.
This is just how you can have a massive 900W power supply. You can draw 200W, 300W, etc. but you can't have a 300W power supply and try and draw 500W (unless you like smoke, fire, explosions, etc.)

John is correct. The USB standard 5V is the important bit. Doesn't matter if the device can supply 0.5A or 5A. Most PC USB ports are good for 500mA, the OEM charger is good for 750mA.
A few of my friends have Motorals RazR's that charge via a mini USB, I don't have to worry about packing a charger when staying overnight.
I already had a collection of USB style chargers and mini USB cables before I got the X1. Use my laptop or a Belkin charger (1A) I got for the iPod in the lounge room, a generic USB phone charger in the car (500mA), the OEM SE charger in my bedroom etc, etc.
At 1st I thought oh no, my 3rd SE phone, my 3rd type of memory card and 3rd tye of charger - but I was a winner with the mini USB

Make non-motorola charger work?

So this is my first motorola and I had heard of the issues they have with non motorola chargers. Now I am experiencing it first hand. With the same ac charger I have charged many phones with and is capable of 1 amp output (D4 charger is only rated at 850 mA) my D4 struggles. With the device off it charged painfully slowly. While on it cannot even charge. It discharges while plugged in despite the charging indicator and reporting "charging (AC)" in status.
How does it know it is not a moto charger? Is it just about the resistance between the data pins? For most other phones shorting the data pins on the charger indicates to the phone that it is a high current charger and not a computer USB port. Is there a similar trick for motorola phones? I would rather not have to purchase an overpriced moto oem car charger. I have a perfectly fine 1.2 amp car charger soldered directly into my car's 12v system behind the dash. Can I make it work?
Thanks!

On a regular basis I successfully charge my D4 using both a charger from a Samsung Reality feature phone and from a B&N Nook Simple Touch, in addition to the one that came with it. I've also used a variety of car chargers.
Sent from my DROID4 using XDA

Actually, so far I have only one charger that had any trouble charging the phone (it was a $3 charger with 2 USB ports), but the $3 charger with ONE USB port works fine, as does the Nook Color charger, Blackberry charger, and Samsung charger I have tried it with, as well as both my old car charger and Lenovo's always-on charging port on their laptops.

Not sure how it knows one way or the other. I've successfully used a few LG chargers to charge my D4. The only really hickup I've ran into is the usb cables from those lg chargers won't sync data to the phones when plugged into a computer, they'll still charge off the usb port but won't read as a usb connection to the computer.

Heh, captcha is trynply.
Every charger I've used, including an old charger for an EN-V, kindle, supplied, and various other phone chargers works just fine with this phone. Probably have a bad charger, guy.

Thanks for the replies. I guess I was wrong. My modded car charger works just fine. I guess its just time to retire the old charger that I have been using. I think it might be my old nexus one charger.

A more important question would be does the thing charge over computer-bound USB ports?
When you're without a charger, but there's a USB cable that fits your phone, sometimes a regular USB data port is the only that is around... even though it might take a really long time.
Try a computer bound USB port, then try your actual charger, again. Or do the hard reset (vol down plus power, hold until it actually does it), which is just like pulling the battery.
See how that goes.

It does in fact charge via USB port. In fact, it has a 'charge only' mode. Depending on how much juice your port puts out, and what you are doing with the phone, it will charge slowly/not at all, though.

from my experiences, the droid 4 will not accept lg microusb cables, the charging bricks work tho. i use a blackberry microusb on mine along with a Logitech and the stock moto ones. 1.2 amps is a bit high but not crazy sounding. personally, I charge at 1 amp.
