Ok guys,
I just checked the voltage output of the official Tascam adapter unit and it's got a 5V - 1.5 amp output rating,
so it appears my HTC AC-USB Charger Adapter plug (5V - 1 amp)
will
not provide sufficient voltage output to the recorder.
Don, I suggest you check your AC-USB Charger output specs as well,
as insufficient output will put an undue strain on (and possibly burn out) the power adapter,
and possibly even eventually damage the recorder.
Fran, thanks for the heads up.
I'm
not taking any chances so going to look around for a similar adapter you found that's got the specified output rating required: 5V-1.5 Amp
