Charger HTC specifications

---

What are the specifications of the official HTC chargers ?

I mean not the voltage/amp, but the way the phone identifies that it is its genuine charger and it can draw max power (ie. up to 1A).
Since normally with a real dumb charger via usb it should not draw more than 100mA (or maybe 500mA but even that would not be USB specification compliant without a proper USB negociation).

I guess this is something like 2 pins shorted on the charger cable ? (or some phones use a specific resistance between 2 plugs as identification)
If I want to charge at max current with a usb car charger, what can I do (short pins) ? And what will be the max current it will try to draw ?

The charger and usb cable provided with my Magic both have standard shaped mini usb plug. Though my collegue's HTC Dream came with HTC shaped mini usb plug. Is there any difference exept in the shape of the plug ?

Current drain

Hi

I have charged my sapphire with a power statin and it indicates about 800 mA of maximum current drain.

I made the charging wire myself from a broken charger so i think you can use any car charger.

The htc shaped mini usb is only to indicate it has charging wires and audio wires.
