It is a bit too early to know, hAP be Media devices have not yet been delivered to customers or if they have on some markets there are not yet reports on the forum of people actually having got one.
I would expect, starting from a max power of 20 W (without attachments)
idle (< 2Mbps traffic), no containers running, with disabled Wi-Fi 35-40% ->7-8W
idle (< 2Mbps traffic), no containers running, enabled Wi-Fi -> 35-40%+2 x 2-3 W= 11-14W
idle (< 2Mbps traffic), 2-3 light containers running (like Pi-Hole), enabled Wi-Fi -> A suffusion of yellow (seriously, hard to say, it will also depend on the USB storage device used, if any)
but the above is just like my opinion (you can call it an educated guess, at the most ).
