Yes. I measured mine, which is the older style "big" one, not the current more compact model.

According to my notes, it was using approximately 1 W (with 240 V mains, if that matters).

I didn't note the exact figure - the meter had higher resolution but the power adapter was using so little power that I didn't care.

From memory, it was somewhat less than 1 W and I rounded it up.

I have the same "big" one, too. Glad to hear that someone made the measurements.
