Will a Hermes Car Charger work on the Kaiser?

[ZzFDKzZ]

I remember reading in a review long time ago that it wouldn't work. Just wanted to confirm this. Thanks.

All Hermes Chargers and Headset Adapters work fine, some cradles work OK too but the fit isn't perfect.

Thanks for the info!

what about the batteries from the hermes ?

Woah I forgot all about this thread.

That free HTC car charger that AT&T sent for the 8525 didn't work on the Tilt.

It worked fine on mine.

Nope, they won't fit.

Any Mini-Usb charger should work on the Tilt or any other device with a Mini-Usb port. I have used my Razr's on my Tilt and Hermes and on a sony and a nokia.

I think we need to settle this once and for all.

The Kaiser ExtUSB Connector...

http://forum.xda-developers.com/attachment.php?attachmentid=31649&d=1164664052

As we see the USB Connectors are on the Top and the "specialized audio connectors" on the bottom. Notice Pin 1 is Power, No other are power.

Now lets look at Mini-USB Series B, the standard USB connector on these Chargers.

Notice When you hold the Mini-USB Type B Connector with the Shorter part down that Pin 1 is to the far right. Pin 1 is also Power.

Mini-USB Type-B Pinout & Cable Color Code

Pin Wire Color Function
1 Red V BUS (5V)
2 White D-
3 Green D+
4 Not connected ID
5 Black Ground

Now we look at the ExtUSB diagram notice the bezel near the end with Pin 5. Notice Pin 1, which we know is Power, is to the "left." It matches up perfectly with Pin 1 Power on the USB Connector.

Also notice on Mini-USB Type B that there is no Pins on the Bottom to interfere with The Extra Pins on the HTC ExtUSB port.

So as long as the charger only provides power on Pin 1, which any good charger will, it will work with the Kaiser.

The USB specification provides a 5 V (volts) supply on a single wire from which connected USB devices may draw power. The specification provides for no more than 5.25 V and no less than 4.75 V (5 V±5%) between the positive and negative bus power lines. Initially, a device is only allowed to draw 100 mA. It may request more current from the upstream device in units of 2 mA up to a maximum of 500 mA.

[...]

On-The-Go and Battery Charging Specification both add new powering modes to the USB specification. The latter specification allows USB devices to draw up to 1.5 A from hubs and hosts that follow the Battery Charging Specification.

So If the Charger Provides up to 1.5A via Pin 1, it should work.


*Caveat: I don't know for certain that the HTC Kaiser draws 1.5A, but I'm sure it does. Hypothetically, on a USB bus the Bus will not provide more power than the Device Actively draws. So if for some obtuse reason HTC went against all Smart Design and Engineering, and created a Device with a Mini-USB Type B connector that couldn't handle 1.5A. A charging only charger that feeds it 1.5A it may blow it out.

I could not find any information on this. If someone knows or has a data sheet that says the HTC Kaiser can draw up to 1.5A then any charger that doesn't provide more then 1.5A will work fine. Any decent Charger maker would know that USB devices cannot handle more then 1.5A. Thusly not providing more then 1.5A on a charging-only charger.

Thanks for the info. I posted this back in '07 before the Kaiser came out.

Also the free adapter that the Cingular 8525 came with does not work with the AT&T Tilt.
