Simple question and a simple answer. +rep to who's ever right! :)

as in my previous post, they use the same amount as if the phone was plugged in.

as in my previous post, they use the same amount as if the phone was plugged in.

OK I have done a mini test:

Household consumption with charger unplugged: 218 w/h

Household consumption with charger plugged in and no phone attatched: 218 w/h

Household consumption with charger plugged in and phone is attatched: 225 w/h

There you go then.

what the hell kind of unit is "w/h"?

Watts per hour.

Sorry you are trying to say that a mobile charger uses the same as when no phone is attached, I have given you the evidence and you post a picture? So does a charger use the same as when a phone is attached or not? No it's not the same.

Watts per hour.

Conflicting answers!

I don't know who to give +rep to!

there is no such thing as a watt/hour. your test is idiotic. i wish people who dont have a clue what they are talking about wouldnt post in threads such as this.

yes a charger DOES use the same amount of power whether a phone is plugged in or not

How is my test idiotic, that was how much my house was using in watts (is that not an electrical measurement?) every hour (measurement of time). So if my house was using more electric when the only thing that changed was the phone plugged in then surely that means it's correct, please explain if it's not though.

like i said, if you dont know what your talking about, dont post.

No it's a forum where you discuss things, unless you are going to prove me otherwise I don't understand why my test is not correct?

Having a light bulb, for example, plugged into a socket without it being on will not use power.
Any device that uses a transformer WILL use power (i.e a phone charger) as the principle behind this is that the current induces a lower current in a different circuit that is open (i.e off).

other devices such as T.Vs on standby use some power, however it is reduced from the full power. if the tv is off it doesnt use any.
video players etc which have displays eg. time even when its "off" will use power.

hope that helps

I will admit I'm not a scientist so don't really get what that link proves. My post explained that having the charger plugged in with no phone does not use the same electric as if it was plugged in, if you don't think that was correct can you explain? I genuinely am interested and would like to know.

isn't it the standard unit electricity consumption is measured in?
