This comment isn't trying to convey the capability, it's talking about the physical size. Perhaps you want to know about the DeltaV, and perhaps at some point that should have been mentioned, but at this point, that's not what they're talking about.
You cannot really talk about deltaV capability for a thruster. You can talk about specific impulse, power usage, power dissipation, total impulse. But deltaV implies you know the size of the satellite, which varies for all their customers.
