Overview
A plug-in carbon monoxide alarm from Kidde, model COP, with 2 AA backup batteries, a rotating plug for vertical or horizontal outlets, and a loud 85 dB alarm. Built for homes, apartments and rental units where an outlet-powered detector with battery backup covers power outages.
This is a basic AC-powered CO alarm, not a smart or app-connected unit. The battery backup keeps it working through outages, and Kidde markets it as compact enough to pack for a hotel or rental stay, which is the main thing separating it from a hardwired wall unit.
- Model COP, UL 2034 5th edition tested and ETL listed
- 85 dB alarm with LED hazard indicator
- Test and hush button
- Includes 2 AA backup batteries
Who it's for
Renters and homeowners who want an outlet-powered CO detector rather than a hardwired system, plus anyone who wants a spare to bring on trips to hotels or short-term rentals. Not for someone who wants smartphone alerts or a combined smoke and CO unit.
Pros and cons
- Battery backup covers power outages
- Rotating plug fits vertical or horizontal outlets
- Compact enough to travel with
- 10-year limited warranty on the alarm
- No smartphone or app connectivity
- Detects CO only, not smoke
- Occupies an outlet rather than mounting to a wall
Performance notes
The unit runs on 120V AC power with 2 AA batteries as backup, so it keeps monitoring through a power cut. An LED indicates hazard status, a test and hush button lets you check function or silence a false alarm, and Kidde states it has no nuisance nighttime chirps. Power surge immunity is built in to help it keep working through electrical spikes.
