Was/is this term commonly used on similar adapters?

I never heard of this term before, but Google exists. ;-)
Take a look at this Wikipedia page: https://en.wikipedia.org/wiki/Battery_eliminator. The section on the historic background may explain this special term.

So this Rockwell charger is a device that can (1) charge the battery with its 4,5 V /100 mA output, and it can also (2) power the calculator directly with 7,5 V / 50 mA.

I think in German this would simply be called "Netz-/Ladegerät", i.e. a device that can be used as a charger ("Ladegerät") as well as an AC-adapter ("Netzgerät").
