[ICOM] Icom T90A wall charger question

[Jim Miller]

I went through this dilemma when I first got my T90.  My question was about
WHY they would allow the operation of the T90 from the cigarette lighter
"charger" but not allow it from the wall-wart.

I finally purchased the cigarette lighter charger also.  I thought maybe the
car charger had a voltage limiter in it and that they didn't want the T90
operated on the 12v I measured from the wall-wart.  Wrong.  My conclusion
after getting the car charger and finding the same charging voltage from it
as the wall-wart, is that the wall-wart will not supply the necessary
current to operate the radio in transmit and that the car charger will.  I
believe this to be true now and that the charging plug effectively removes
the radio battery from being able to supplement the charger when attached so
the charger has to be capable entirely on it's own of supplying all current
necessary for transmit.  YES, I HAVE used the radio on the car charger in
transmit and it works fine as documented.

The car charger is cheaper than an additional battery and the charge time is
much less even with the radio on and mostly monitoring.  You can add a
gelcel carry pack (several amp-hours) for quick recharges while still
operating if you have to be portable all the time.

73, Jim

Thanks Jim,

So I am assuming that any 12 volt 200mah wall charger should work. That is
interesting since the manual recommends using the special CP19 cord when
running the radio off of a cigarette lighter, and that is supposed to lower
it to 11.5 volts.

John,

Just happened to have one right here on my desk.

Its rating for output is 12 VDC at 200ma.

Can someone who has a T90A look at the wall charger and tell me the voltage
and current ratings for it.  It is listed in the manual as a BC110AR, but
the specifications are not given for it.
