It could be implied that it's just a power supply with a tremendous amount of output, while the boosters and the cores have engines themselves so it's probably using either KW or W. Correct me if I'm wrong but afaik about 10KW (10000W) is the power of a high-output diesel generator used as a back up or a portable power supply that can last thousands of hours. Sounds fitting for an AC generator to me.
I think the "engines" located inside the boosters and OB cores are a fusion of air, this, and car engines; aircraft engines are light and powerful, but have low initial accel, while car engines are about 2-3x heavier. It may use a fictional unit, or it may either use Thrust or Horsepower for the boost speed. I'd like to think that the OB core and booster "engines" in the AC era have somewhat been perfected or advanced to another generation.
Of course, go look for sources if you're curious; I've already closed my tabs and it'd be a pain to look for them all again.
