Soundbars draw 10 to 60 watts depending on size and volume. Models with a separate subwoofer draw more, and the subwoofer has its own standby draw.
A typical soundbar (25 W) costs $0.007 per hour, or about $0.81 per month at 4 hours a day in New Hampshire. Cheap to run
| Wattage | Per hour | Per day | Per month | Per year |

- Unplug the subwoofer if you rarely use it.
In standby it draws about 1 W, which adds roughly 9 kWh ($2.37) per year if it is never unplugged.
