Carbon monoxide detectors typically consume very little power, often operating on a minimal amount of electricity whether they are battery-powered or plugged into a household outlet. For example, a plug-in detector might draw just a few watts, comparable to a small LED nightlight. Battery-powered units utilize the stored energy within the batteries, which may last for several years depending on the specific model and usage.
Minimal power consumption allows these life-saving devices to remain active continuously, providing constant monitoring for the presence of carbon monoxide gas. This continuous operation is essential for home safety, offering early warning of potentially lethal CO leaks. Historically, before electronic detectors, detecting this odorless, colorless gas was exceedingly difficult, making these devices a significant advancement in home safety.
