  Does this actually work?  The 770/n800 need current-limited power,
and I would think the direct USB connection would feed it too much
current.  Too much current and the 770 will refuse to charge or
possibly damage it.  I bought a USB phone charger adapter and soldered
a nokia phone plug onto it.  The USB phone adapter boosts the voltage
to 6 volts and limits the current as well.  It looks very similar to
the Nokia one except it has a female USB plug on the other side (to
plug phone adapter plugs into).  Works pretty well but doesn't seem to
charge as fast as the standard AC adapter the 770/n800 ships with.
