So would this mean things like guitar amps and toasters take up energy when off but plugged in? Also is it very bad to have your alarm clock plugged in at all times? If I unplug it I have to put in the time again when I plug it back in..
Okay but how does a device draw power when off? Isn't the circuit broken when it's off. Or for cables that aren't connected how is the circuit connected. It doesn't make sense to me.
Because some devices aren't "truly off" when you press the power button, they are in standby mode. They are constantly scanning for user input every millisecond, and they need power to accomplish this task.
A charger will indeed not consume any power if there is "nothing" pluged into it. However, it may consume electricity if something is pluged into it but is not being used or is not switched "ON". For e.g. if you have a Television plugged into the socket, but the TV is not "ON", it will still consume electricity in standby mode.
@@ScienceABCII it would be good for this type of video to give numbers, sources, and testing of those two. This video more or less say "trust me bro" without those.
@@ScienceABCIIhow about a gaming laptop battery which is big and serves as its power supply? What if the charger was plugged in but not connected to my laptop? Will it still consume electricity?

Measurements, data, please... mW of a typical unused usb charger...?
25 kWh per month or yearly
Thanks for this information. I was looking for this from quite some time!
Wow! That was the first video suggested by my search. You answered my question perfectly, thank you!
We are glad to hear that!
Anything that lites up or desplay led uses electric, you should not worry not a whole lot of power
Don't worry , you can always buy a few solar panels

Can you show some proof? Cuz I just watched a vid that chargers doesn't consume power when there's nothing plug into it.

Very helpful
Glad you think so!
This vid coulda been a min or 2 shorter
Thankyou !

this doesn’t answer how much money u waste by leaving things plugged in
