I have a g2, but looking for a universal dock with separate connections for micro-usb and AC to allow for simultaneous fast charging and sync connection to a PC. Does such a thing exist?
Don't think so, since those 4 USB pins are all connected to the charger (2 for power +/-, and 2 to let the phone know about it's higher charging capacity), leaving no room for a standard usb connection any more.

Sorry if this has been covered elsewhere; I couldn't find anything.
I'm looking into getting some spare chargers for my Tilt. I read at Pocket PC Techs that the device has a distinct "fast charge" mode, that uses a special pinout. Is this true?
If so, does the charger that comes with the Tilt use this fast charge mode? It seems to be just a standard mini-USB charger (data sheet here).
The link to Pocket PC Techs is actually to an adapter that they sell that is suppose to give you a fast charge with any USB charger. I'm wondering under what circumstances I'd have to use this.
Anyone know what the fast charge pinout is, and which third-party chargers use it?
Thanks.
ISTR reading something about pins 4 & 5 being tied together on some chargers -- should be very easy to test this.
I have not tested this but I suspect the pin out is the same as the Hermes:

The USB charging is done with different connections and at a different mA rating. The mains charger is 1000mA and is what I would call the normal charging system (but what the site you show, refers to as fast charge - but only by comparison to USB charging) This is just about standard for many sync/charge PDAs and not a special feature of the Kaiser.

I do notice a huge difference in speed comparing my old razor usb power adapter vs usb cable into my computer vs tilt power adapater so it prolly makes sense

Yep, the Razor adapter only delivers 500mA not 1000mA

Plus the razor charger does not have the pins 4-5 shorted, this is a HTC tweak that lets the phone know that it's on a charger vs std. USB power and it may in fact charge at a higher rate upon detecting this. I just know that my Hermes occasionally did strange things like turn off BT radio and other odd things when connecting/disconnecting from different chargers. Kaiser seems better at this.
For a couple of weeks now, I have been charging my Kaiser at work by using the adapter that came with my Audiovox SMT5600. It's been working fine. I cannot however determine if this charges any faster or slower than the Kaiser's adapter.
Slow Charging
So that would explain when I use GPS in the car with my old RAZR charger why the battery still drains. Darn, looks like I'll have to buy a new car charger.
USB Charging
are there any issues iwth battery drain or lif when charging with the USB cable connected to a computer?
Thanks,

Is there a specific USB charger.
The pin out is the same as the Hermes?

I wouldn't think it would need to be tested. As per this page:
HTC has developed a range of accessories that are compatible across all HTC devices for consumer's ease of use. These include the BH M200 (Bluetooth headset), HS U110 (3.5 mm audio adapter and headset), and the HS S200 (HTC standard stereo wired headset) to enable effective communications on the move.

If the audio adapter and hard wired headset are compatible across all HTC devices (per HTC themselves), then that confirms that the pinout of the audio side is the same. And it's been mentioned earlier that the data side follows the mini-usb standard, which I can confirm: I'm using the usb cable from my camera to connect my Kaiser to my PC at home, while I use the supplied cable to connect it to my work PC.

I would like to use my old Himalaya MDA II Hands Free DSP Car Kit for my new Kaiser (as that I only have to buy a passive holder).
I tried to find a ExtUSB 11-lead Pre-wired Connector Plug ....but it is impossible..any suggestions?
It should be something like this one http://www.gomadic.com/comip10leadp.html
Sorry, can't help you there.

I am experiencing a similar issue with an USB/car adapter and the USB cable that came with the Tilt.
Ran Google Maps yesterday with GPS on and when I got home my phone was almost empty. It was charging the whole time in the car though.
Does this mean I should look for another USB cable that is shorting those pins?
What about these adapters that plug into the phone and allow you to connect a USB cable for charging and a 3.5mm audio plug?

Mmm, that is a unique piece!! But the cable seems somewhat short.
I think at the end..I am going to combine following pieces to make the final connection to my old handsfree carkit.. (I hate soldering)

Any problems with me using my old Razr car charger on my Kaiser? Typically I charge mine every night with the standard charger but in case of emergency I'd like to use my Razr car charger
Thanks
In answer to the original question, yes, pins 4 & 5 are shorted on the OEM charger that ships with the Tilts, thus enabling it to fast-charge the phone at currents greater than 500ma.
Hopefully this helps,

I came across this hub:
http://www.monoprice.com/products/p...d=1030702&p_id=9955&seq=1&format=1#largeimage
Looks pretty nice, all USB 3.0 ports, capable of supplying a 900ma of power to each port. Good for all sorts of things, not just a tablet being connected to the computer.
What I was wondering about this is would it be possible to open it up and short the data pins so that it is only capable of being a charging device? If so, it probably wouldnt even need a connection to a PC, just need to be plugged into the power adapter. I am wondering on this because if possible, that would mean when only using 1 port it (theoretically) would be capable of sending 3.8A out to the one device if the device tried to pull that much. Since the tablet would see the shorted connection it should at least try to pull 2A. Anyway, I just thought it would be a fun project to try and modify in this way. I will probably get it soon and attempt this myself, and might even look into beefing up the internal power circuit area to make sure it can safely send 3+ amps out one port if asked to. It would be nice to use this in conjunction with a pogo connector and finally be able to charge faster than the tablet drains while gaming.

Nexus 10 USB specs "microUSB v2.0"
http://www.gsmarena.com/samsung_google_nexus_10_p8110-5084.php
Would you get value from USB 3.0 ports with a USB v2.0 interface?
To get the full USB 3.0 power of 900mA, the device has to be configured as a USB3.0 device. The hardware developer USB 3.0 command verifier tool is separate from the USB 2.0 one
I thought we had also verified the USB connector and the POGO connector are mutually exclusive in power terms, even if the charging circuit inside the Nexus 10 could be modified to accept more than 2.5A.

Sorry, I dont scour the threads in accessories every day so thats news to me. Besides, I dont even know what "mutually exclusive" is supposed to mean in relation to this. If the pogo connector has a USB end and draws 2A from the power adapter, why wouldnt it be able to draw 2A from any source capable of putting out that much power? Your trying to tell me that the pogo connector somehow signals it is a USB2.0 device? If thats the case it wouldnt be able to draw more than the 500mA. The regular power adapter has a USB output connector after all and it can send 2A just fine. This hub has its own power adapter and doesnt try to draw the full 3.8A through a computer connection. What is the difference between the power adapter that comes with the tablet and a hub that has its own PSU to output that much and more power?
and yes I know it wouldnt transfer at 3.0 data speeds since the tablet has a 2.0 port, but I wouldn't be using the USB port on the tablet. But why would the USB somehow signal that it will only send 500mA through the pogo connector?

Mutually exclusive: charge from POGO or USB, but not both at the same time

The POGO connector, although it connects to a USB port, is not bound by the USB specification for how much it can draw. USB chargers are available that can deliver up to 3A, but it's up to the device to request this much power.
The specifications for USB 2.0 of 500mA (and 900mA for USB 3.0) are for a power and data connection, but their is an added specification for power only of 1.8A (and 5A for USB 3.0). a hub will generally adhere to the power and data specification, while the USB PSU has no data functionality (this is determined by their being a short circuit on the D+/D- USB pair).
The reason a USB 2.0 device will not draw 900mA from a USB 3.0 port, is because it's the device that negotiates the connection, and as a USB 2.0 device, it will only request the 500mA maximum from the USB 2.0 specification.
Try to think of it this way: an incandescent light bulb will not be any brighter if you increase the power source current.
Ok, but you just said everything I was talking about. So when I modify the hub to get rid of the data connection, and not even connect it to a computer and just have its power supply connected, how would that be different than simply a normal charger? The tablet would be charging through its pogo connector, and it simply plugs into the hub with a 3.8A power supply. So it wouldnt have anything to do with any USB limits then right? Cause the hub is USB3.0 ports capable so it is not like a USB 2.0 hub that wouldnt have the proper internal circuitry to push the 3.8A I will be trying to draw.

If you short the D+/D- pins, you can then use the hub as a standard charger PSU, capable of delivering 3.8A.
The issue is that current gets pulled, not pushed. It doesn't matter how many Amps you provide, the Nexus 10 charging circuit is only capable of pulling a maximum of 2.5A. (datasheet for the charge circuit can be found here).
From earlier posts (in one of the POGO threads, I think), there were found to be kernel limits restricting the SMB347 charging to 2A.
Has anyone gotten OTG + charging working on the Turbo 1? Meaning, having a USB peripheral connected and the Turbo charging at the same time.
I'm using a USB DAC in the car connected directly to an amp. Sound is amazing. Would be cool to charge while playing music.
TIA.
I've tried to accomplish this on my Turbo 1 using hubs and splitters and whatnot. I am pretty certain that when an otg is plugged in the phone is incapable of receiving any current alongside the flash drive, since while using otg the micro usb port is in a sort of 'out' mode, so to speak. The only way I've found I was able to use otg+charging was to wireless charge. The phone gets a bit hot but that could be because I was otg-ing a straight up HDD; with a flash drive I'm not concerned it'll get too hot, and it definitely won't overheat. Let me know if you find other solutions
I have a Beklin Wireless Charging Pad 10W and it works fine with my XZ2. However sometime I need to share my mobile network to the laptop, and every time when I plug the USB cable it will automatically change to get charge by USB.
Of cause I can keep the wireless charging by using the hotspot feature, but I find that hotspot + wireless charging + once opening some other apps it will make the phone overheat and I often get the overheat message. Therefore I am curious, is it possible to keep charging by Wireless Pad and share the mobile network with USB cable?
Thank you!
Hi there!
My life does not match any pattern, that's probably why the new Smart Charge feature does not really work. I manually stop charging around 80% whenever possible. However, I frequently travel by car using Android Auto which requires me to connect the phone to the car using USB. It will ALWAYS charge to 100% when connected. Are there any options to disable charging at all? Are there USB cables which do not charge but rather provide a data only connection? Do you have any other suggestions?
You can't do it.
Usb data transfer needs +5v.
You can make a usb cable charge only, but not a usb cable data transfer only.
