One of my customers has 2x of these and they are drawing ~10watts each on average, however they are not very busy if truth be told.   As Virgo said, budget 20w and you should be good

@Virgo 

Thanks for the confirmation. I thought that Maximum Power Consumption was the magic number I needed to hit - but wanted to be sure as I set about selecting switches for this LAN.

 I anticipate averaging 15-20 active Wi-Fi connections with bursts up to 50 during the workday. 

Now I'm curious if connecting the APs via 2.5GB is significantly better than 1GB. Rather than muddy this thread, and presume upon your good graces, I've posed that question in another thread. https://community.tp-link.com/en/business/forum/topic/619238?page=1

Thanks again, guys.
