Saw this on the box of a two line business phone. Was curious what accessory this PowerBook was sitting on.

A Technoggin PowerPlate perhaps?

Neat. I figured it was some kind of external battery. I like how nowhere in that ad do they mention how much they weigh.

Maybe even more than the computer itself.
