A bit of both @skyebend. The tables see a lot of use by students around lunchtime, with students having lunch and charging phones. They see moderate use before and after lunch with people studying and charging laptops. During prolonged outages, you'll see people bring their powerbanks and laptops for charging.

The day I took the picture, the 7 tables closest to my office were occupied, and I had to walk over to another faculty to find an empty table.
