Q. e.g. lamps, phone chargers, laptop chargers etc. also do chargers still use electricity when they are plugged in but not connected to laptop/phone?
A. A ceiling fan might be as much as 300 watts on high speed.
A powerful stereo could draw a lot of watts.
Space heaters are the worst, usually 1500 watts.
A vacuum cleaner is usually close to that too.
A very large LCD might draw 180 watts.
A piece of exercise equipment like a treadmill or stepper could have a strong demand.
A powerful desktop computer with upgraded graphics and such could draw as much as 600 watts at full capacity.
Yes, any type of plug that is bigger than a standard lamp plug has some form of transformer which uses induction to change voltage, and even when you don't pull power from that transformer it consumes a very small amount of energy. It's really trivial. If you were to add up the phantom draws of your entire home it might add up to 10 watts of power.
Your laptop charger might draw .2 watts at worst. But more like 70 watts when it's powering your laptop.
