Icom IC-A14 detailed questions

I need to replace my 24 year old crew radio. The current radio sits in
it's charger base 98% of the time, with the charger power on. At home,
it's connected to an external speaker that's in my wife's sewing room
and to an antenna on the roof; in the motorhome, we use it's internal
speaker, but it's still connected to a roof antenna. It might get
removed ocasionally for use as a handheld.

The A14 looks like it would do the job, mostly. I'm hoping someone
already knows the answers, so I don't have to wait till Tuesday to
contact Icom...

1) Can the A14 be powered externally while it's in use? This could be
cord from an external power supply or cigarette lighter socket, or a
charger base that it sits in while turned on (the manual says it must be
off while in the supplied charger base).

2) Can it be left on charge indefinitely while turned off?

Any pertinent comments are encouraged.
