In reading the documentation for the 2000c, the manufacturer expects

FYI

But old planes tend to have crappy ship power outlets, frequently they are
even disconnected...


And the manufacturer says in that case, you can use a supplemental battery
supply which they can sell you. Most people who purchase the unit will have
ship power though, and won't need it.

My point was that it is unreasonable to expect the unit to do something which
the manufacturer says it is not designed to do.
