Well the datacable for c155 is a T191 so 3.3v. This is not the answer to your question but
i hope it helps. ;)

But well, that is not really true. There are 2 versions of the charger,
the normal heavy one with transformer, and a light SMPS-one.
The first one delivers 5.94V without load, and the SMPS-version even
6.38V. The SMPS-one states "5.0V 350mA".
You need at least > 4.2V, since that's the voltage the battery is being
charged to.
And of course the datasheet of the used charging regulator, Intersil
ISL6292C states:
What voltage
is written on the charger?
230V≈ :-)
... and 3.6V, 600mA Supply Voltage, VIN . . . 4.3V to 6.5V

the charger works @5V, but I recall that a resistor is needed for the phone
to detect the charger as an original charger
I think your best choice is buying one off ebay

The charger uses a 2-pin connector, so where do you think an ID resistor should
be used? Motorola uses ID resistors in their mini-USB based chargers, but for
a 2-pin connector, I don't think that is true.

we are sucessfully charging our mobiles with a 100ohm resistor in parallel
to a 5V supply, so like galileo said, "but it moves" xD
