Power cords

By toastedbagel on Apr 17, 2008

" "

If I have a power cord(such as a laptop cord) that is plugged into the wall and not attached to the appliance(computer), will the cord still take up energy coming from the wall, even if not attached to it?

Yes,

You will constantly draw power from the outlet. Though it may not be as much draw as if you were running a device on it. Try picking up the AC adapter one day when not plugged in to the laptop. It still gets hot.

On another note,
When using AC power you should ALWAYS plug it into the back of the device before plugging it into the wall outlet to avoid excessive power surge.
