is used to power up a piece of electronics which has been in storage for a long period of time, to allow the capacitors to reform, hopefully without self-destructing.
That ebay bucking transformer is meant for constant use, to drop the AC wall voltage from today's higher averages (>120 VAC) to 110 or 115 for devices which were designed to use lower voltages.
You're right that someone could DIY one for themselves fairly inexpensively if they know which end of the soldering iron gets hot, and feel safe with wiring projects.
