Is there such a thing as a power sink equivalent to a benchtop power supply, where I can set the wattage (voltage, amperage) to be consumed?

What is this device called?

    \$\begingroup\$ Two-quadrant power supply, at least. Look over this page. I think it will become clear. \$\endgroup\$ – jonk May 10 at 23:04

    \$\begingroup\$ This is a bit like asking if there's a device out there that can somehow measure a voltage. A quick google should have solved it (since you work there). Every manufacturer of electronic test gear makes these. "This question does not show any research effort". \$\endgroup\$ – pipe May 11 at 11:21

Yes there is, it is called an electronic load.

    \$\begingroup\$ the was an open source one on kickstarter a few years ago... kickstarter.com/projects/nickjohnson/… \$\endgroup\$ – vicatcu May 11 at 0:55

    \$\begingroup\$ @vicatcu it's really an established thing, and I'm not sure how useful a kickstarter from a few years back in a professional environment is if the shop they link to is down... and 25 W max power? Oh, cute. \$\endgroup\$ – Marcus Müller May 11 at 10:58

    \$\begingroup\$ I don't know, awareness of open-source designs is helpful imho \$\endgroup\$ – vicatcu May 11 at 12:38

    \$\begingroup\$ @vicatcu For that purpose, it might have been more appropriate to link to the design sources directly instead of their kickstarter pager. \$\endgroup\$ – Bergi May 11 at 21:38

    \$\begingroup\$ @Bergi thanks, I didn't have time and that was the first thing that came up when I Google'd so I shared it. \$\endgroup\$ – vicatcu May 12 at 1:40

You might be looking for a Programmable Load Bank.
