Wifi router electricty usage

[Speedster]

Has anyone ever measured the electricity usage of a wifi router? Both my TP-Link MR3420 and Huawei B315 run off 12V 1A adapters which, by my reckoning means they should be in the region of 12w. Running that 24-7 for a month works out to 8640w (12*24*30), which is about R16 per month in electricty costs (at R2/kwh). It's not too bad, but adding 2 or 3 APs adds up pretty quickly. Is this correct?

Never done the sums, but will do now. You have given some food for thought, what about the pi's and all the the esp's and other toys that I just put in all over the place, maybe my hobby is costing more than I think.

They don't necessarily draw the full 1A all the time though. You'd have to measure it

Can't find yours, but most TP Link consume between 5 and 8W.
