Typically difficult to rate a turbojet in terms of power, but we could look at the fuel flow (energy) rate a momentum metric. In any case, we know it needs around 100kgf thrust, which can be easily obtained and installed, and we know this sort of control system, if not the mechanism (maybe it uses gimballed units) is easy to get.

The thing is, while this one has low fuel efficiency, but excellent power/weight and cost*mechanical*complexity/performance, there is an increasing number of new devices coming out which perform a similar role and with longer endurance, less noise, less jet velocity etc.
