Oooh, the it seems i missunderstood the previous Messages. I was sure
that there is NO Charger
for the NEO Except the USB Port of a Computer. Im sorry :(
Greetings

I read the Archives and found this Topic. I own a T-Mobile MDA Vario.
The device is
charged via USB too. And theay included an USB Wallcharger. Have anybody
allready checked
this charger?
Device Data:
Delta Electronics inc.
AC Adapter HTC P/N: 79H00051-02M
Model: ADP-5FH C
Input: 100-240V~ 0,2A 50-60hz
Output: 5V = 1A LPS
Frequency Level 4
What i've learned so far:
The strange thing with USB-charger is a resistor of certain Ohms (47k IIRC)
that's supposed to connect 2 pins of the charger's plug "to identify
OM-charger".
I can't say whether this is standard for USB-chargers, or what will happen
when NEO doesn't sense this resistor on USB-power detection.
Charging seems to be controlled by the main CPU via PCU-chip. If there's no
CPU control e.g. due to completely flat accu, only a very low secure trickle
charge takes place (->"if you can't power on your NEO, connect to USB and try
again after ~30 min..."). There are chances this will be the same for missing
resistor, depending on what logic is in the "driver".
Maybe one of the devs may shed some more light on this.
