Yes. I tried to find the calculations, but couldn't find them. Google Bard to the rescue (and cutting out the actual calculations she gave):

> Therefore, a black hole needs to be at least 9.49 × 10^{22} kilograms in mass to emit 100 watts of Hawking radiation. This is about the mass of the Moon.

No clue whether those numbers check out.

EDIT: poking bard a bit more gives this correction:

> However, for a black hole to emit 100W in gamma rays, it would need to be very small, with a mass of only about 10^22 kilograms. This is much smaller than the Moon, which has a mass of about 10^25 kilograms.

But poking more and more makes me less and less confident, because bard seems to believe that bigger black holes emit more than smaller black holes.
