Soundbar power specs

A soundbar is rated around 35 W, but the real figure shifts with a few things:

Model and rating: A soundbar ranges from about 20 W on efficient units to 60 W on larger or older ones — a spread of ~40 W.
Usage: the real draw depends on screen size, brightness and volume.
Standby: even idle it keeps drawing ~2 W, which quietly adds up over a year.
Run time: because a soundbar typically runs about 4 h/day, hours of use matter as much as raw wattage on your bill.
