I have a laptop with a recharger (also known as an AC adapter), this is how it looks like:
When I disconnect my laptop from the charger, does it (the charger) still consume (waste) electricity?
I am trying to do math, how many kW I waste every year to keep my adapter plugged in the whole time. I tried to read how much watts does it take, but I am not good with that kind of stuff, so here is some info:
INPUT : 100-240V~50-60Hz 1.5A(1,5A)
OUTPUT: 19.5V(19,5V) --- 4.62A(4,62A)
Does this info help to do the math?
There is 8760 hours in year.
