Maybe I'm misunderstanding something, but isn't the only power
consumed due to wire resistance in the primary winding of the
transformer? Seems to me that should be miniscule.
Most chargers and things these days use switch-mode supplies.
I don't know how much they draw unloaded.
FWIW, I practice unplugging my various chargers when not in use (excepting
the chager for an SLA flashlight which likes float charged). Unfortunately,
a lot of my computer system remains "on" when unused.
