Lionel Transformer

What is the Power Use, of an Average Small Charger, When Plugged In the Wall (Unconnected)?

Thanks g.venkatesan, but One Could Expect a Very Small Amount of Heat Dissipation.
Thanks .*., as I Suspected.
Thanks Very Much Retired EE.

I tested seven chargers and found they use 0.1 to 2.8 W unconnected. The one that uses only 0.1 W when unconnected is a USB device charger. My notebook computer charger has the highest input rating of the seven, 1.7 A 100-240 V but uses only 0.3 W unconnected. The one that uses 2.8 W is a 15 minute charger for AA, AAA & 9 V batteries. It uses 120 W maximum when connected. The average for the seven chargers tested was 0.9 W.

PS-1
I tested three small transformers, a 40 W AC Gilbert toy train transformer from the early 1950's used 5.2 W unloaded. A 5.5 VA Lionel transformer used 0.8 W unloaded. A 9 VAC 0.5 A transformer used 0.5 W unloaded. Average 13%, pretty close to one of the other answers.
