The only Pferdefuss:
Although supplied with a 1000mA AC adapter, the station when HTC Desire reports are only as "USB source," and not as "AC source".
The AC adapter itself should not be a "Dedicated Charging Port" - right on the HTC sees this even a "USB Source".
The original HTC adapter "TC E250" itself announces you as "AC source" - directly plugged into the phone.
Infected the HTC adapter "TC E250" to the docking station - then the cell phone in the dock again sees only "USB Source".
The purpose of this docking station is only charging in at - and I would still expect me "full power".
Too bad! Therefore've also considered the first part to send back because of it.
On closer reflection, however, I realize that can not have both at the same time:
Since the part also has a data port to the PC, it can lead to phone back "only" normal "USB Source" be.
One can consider the "charger only" cradle, or a combination device in which a switch "Quick Charge / Data Link" allows.
Info:
The Dedicated Charging Port shorts the D + and D- pins with a resistance of at most 200 ohms.
That way the Connected Device is allowed to pull more current - approx. 1000 mA.
Without this pinning, the Connected Device will only draw up to 500 mA.
If you use your HTC Desire "full power" (eg GPS navigation plus plus downloads), then it can consume already morethan 500mA, Which Means to effective discharge Even When plugged into the cradle ...
