This post is basically a repeat of: Is there a maximum number of Pis that I can power from the same wall socket?
However my situation is slightly modified. Particularly for wall sockets in Denmark, which based on this link: https://www.worldstandards.eu/electricity/plugs-and-sockets/, the standard is 220-240 V, and 16 A.
I need to plug at least 60 raspberry pi's within close proximity of each other (for science :) ), and i want to make sure i am doing this correctly..
based on this guide: http://raspi.tv/2017/how-much-power-does-pi-zero-w-use, a Pi 3 is using 350mA max, which is what i used for the calculation made in the referenced stackexchange link
my calculation is as follows:
240*16=3840 watts from wall
.35*2.5=.875 watts one Pi 3 uses
3840*.=3264 watts from wall based on 85% efficiency
3264/.875=3730 Pi 3's that in theory could be plugged into the same wall circuit
apologies for the repeated post, but can someone please confirm my calculation that with a 2,5 amp power supply and 85% efficiency, i can in theory plug ~3730 Pi's into a socket (or a number in that range)?
essentially i want to guarantee that 60 Pi 3's will be safe to plug into the same socket. help is greatly appreciated..
