Kidde COPD Plug-In Carbon Monoxide Alarm Overview
The Kidde COPD plug-in carbon monoxide alarm is an AC-powered CO alarm with a backlit digital display that updates roughly every 15 seconds. As a Kidde COPD digital display CO alarm, it includes a Peak Level button showing the highest CO reading recorded since the last reset, and a rotating plug that fits vertical or horizontal outlets without blocking the adjacent socket.
Safety note: this plug-in CO alarm with battery backup is tested to UL 2034 (5th Edition) and is ETL Listed - a genuine code-compliant alarm. It detects airborne carbon monoxide only, not a chemical splash hazard or other liquid exposure risk. If it sounds, move to fresh air immediately, call emergency services, and don't re-enter until the space is confirmed safe or the CO source is identified and resolved. Test it regularly and replace it per Kidde's stated 10-year service life, even if it still powers on.
As a UL 2034 plug-in carbon monoxide alarm, this rotating plug CO alarm plugs directly into a wall outlet, with two AA alkaline batteries providing backup power during an outage and built-in surge immunity for voltage fluctuations. Use the Kidde CO alarm peak level button to check the highest reading recorded since the last reset. This model detects CO only - no WiFi, no explosive gas detection, and no air quality monitoring. See our best carbon monoxide detector guide for how it compares to other Kidde plug-in models.

Frequently Asked Questions
Is the Kidde COPD UL 2034 certified?
Yes. It is tested to UL 2034 (5th Edition) and is ETL Listed, making it a code-compliant carbon monoxide alarm, with a 10-year limited warranty on the unit.
How is the COPD powered?
It plugs directly into an AC wall outlet and includes two AA alkaline batteries for backup power during a power outage, so it keeps monitoring even if the electricity goes out.
What does the digital display show?
A backlit digital display shows the current sensed CO level and updates roughly every 15 seconds. A Peak Level button lets you check the highest CO reading recorded since the alarm was last reset or unplugged.
What is the rotating plug for?
The plug rotates to fit vertical or horizontal outlet orientations without covering or blocking the adjacent outlet socket, which helps with placement flexibility in rooms with limited outlet space.
How loud is the alarm?
It sounds an 85-decibel alert when it detects a dangerous carbon monoxide level, loud enough to be heard through most rooms in a home.
Does this have WiFi or smart app features?
No. The COPD is a standalone plug-in alarm with a digital display, not a WiFi-connected or app-controlled model. If you want smartphone alerts, look at a dedicated smart CO alarm like the Kidde COPDW instead.
Does this detect explosive gas or monitor air quality?
No. This model detects carbon monoxide only. If you need combined CO and explosive gas detection, or indoor air quality monitoring, those are separate Kidde models built specifically for those functions.
What happens if the power goes out?
The two AA backup batteries keep the alarm functioning during an outage, so CO monitoring continues even without wall power. Replace the backup batteries per Kidde's recommended interval so they're ready when needed.
Where should I plug in this alarm?
Install near sleeping areas and on each level of your home per general CO alarm placement guidance, and avoid outlets blocked by furniture or curtains that could restrict airflow to the sensor.
How do I test the alarm?
Use the built-in test function per Kidde's manual on a regular schedule to confirm the alarm and digital display are working correctly, and check the Peak Level reading periodically.
How long does this alarm last before replacement?
Kidde states a 10-year limited warranty on the COPD. Replace the unit at or before the end of its stated service life even if it still appears to power on and display readings.
What should I do if the alarm sounds?
Move to fresh air immediately, call emergency services, and don't re-enter the space until it's confirmed safe or the CO source has been identified and resolved by trained personnel. See our carbon monoxide exposure symptoms guide for what to watch for.

It does the job.
I needed this for a rental property that we are selling. It provides both battery backup as well as plug in power. It is easy to operate, inexpensive and does the job.

Quality CO detector. Worthwhile investment.
Quality Kidde brand CO detector. I replaced my original one with this identical one after 10 years of service, when it finally beeped and showed "END" in the display, which renders it useless, which is by design.Ironically, I never had any CO issues or alerts, until about a few months before its 10th anniversary in service.My home's natural gas boiler was over 25 years old, and begin leaking CO from incomplete combustion issues. This Kidde CO detector audibly alerted me and displayed the current CO level as well as the maximum CO level that it had recorded.Very simple to use and displays basic, yet useful information. I was able to open the windows and ventilate my house to prevent the excess CO buildup from harming us, thanks to this CO detectors audible & visual alerts.Hope they're still making this model 10 years from now, when I will need another one, or if I decide to move and want to purchase a new one. It's certainly not the cheapest CO unit on the market, but it's a good value for the money.Oh, it plugs directly into any standard 110-volt power outlet and it has a 9-volt battery backup, battery included. Although they recommend you replace the 9V backup battery every few years, I never replaced mine, and it was still almost as good as the day it was installed.My Kidde CO detector is plugged into an outlet in our upstairs hallway just outside of our bedroom. Fortunately, it also fit perfectly next to (below) my plug-in doorbell, which was a huge plus!I'm planning on installing one in the basement, near the gas boiler as well. Should have done that years ago, as we would have likely received an earlier "heads-up" that there was a combustion problem with the boiler.One last note: You can remote wall-mount this unit also. Cool feature!If you look at the last picture that I posted with this review, you can see that when the rear access cover is removed to access the backup battery, there is extra cord stored on the opposite side of the battery.The connected main power source plug can be easily removed and relocated/extended, via the corded connection, in order to have the CO detector located somewhere other than directly plugged into the power source.There is also a handy little clear plastic packet included, containing two wood/mounting screws and two wall mount plastic expanding inserts. (Not shown in picture.)Just can't say enough good stuff about this unit. Very pleased with it!

Bought 2 as replacements for my Mom's old similar units
My mom installed 2 of these in her house 7 years ago. They both failed and started going off within 2 days of each other. Might have been just a dead battery. I don't know. She called me and said they needed replaced so I got 2 of the current model and installed them for her.I like that these units have a digital readout feature that allows you to pull up not only the current CO level but also the highest level since the last reset. As someone who works around fuel burning appliances as part of my job, I know that CO levels in a structure can vary, and it is important to know not only what the reading is right now, also to know how high the reading has been previously as CO levels can change as appliances or vehicles run, doors or windows open, etc. Even a high quality handheld unit that the fire department or gas company uses to investigate CO complaints is limited because it only knows what the CO level is right at the moment of the test. Meanwhile, this inexpensive digital CO detector cannot only tell you what the level is right now, but also the highest level it has noted...which is an important data point.I also like the way these units can be plugged/mounted directly to an outlet, or you can extend the plug from the unit and mount it a few feet away (perhaps above) the plug to get it into a better sampling position.I gave this unit 4 stars which is the highest rating I would give any of the readily available home CO detectors. Why not 5? Well, they still have a limited service life (like 7 years), and it would be nice if when they fail they would have a different alarm or some very clear indication that the reason it is going off is it has failed, not because it has detected CO. In my 83 year old mother's case, she had the police out there in the middle of the night because her old detector had gone off...and that is very common. When these units fail, it shouldn't initiate a call to 911. They need to make it much more obvious to the homeowner that the unit needs replaced, but there is no reason to call emergency services.

Remember to replace every 10 years
Bought as a replacement for detector that met its 10 year lifespan. Easy to install by just plugging it in to a wall outlet. Appreciate that it comes with a 9-volt backup battery. A potential lifesaver that functions reliably in the background.

Big improvement 🏆
Upon recommendation for ability, and the fact our current CO detector is pushing seven during renovations. It attaches to the ceiling. Figured replacement early based on quality of function for new device and huge savings to buy two as singles if worth it. As vintage ceiling tile are being installed and this device is flexible as to where it sets up. Can be plugged in with the back up battery or wall mounted with battery alone.Although it’s a bit large has a keen sense of detection. There’s no price or device size that matters with safety. But if ya can score a discount kudos.No matter what detector you buy make sure it has a digital read on how much CO2 is invading when it does.To know what’s safe … 0 😁 all seriousness, under 30. The booklet explains the levels. How the device will function in a warning situation. Symptoms o look out for. How long it’ll take to read CO2 depending on how severe it is.It’s recommended to take one on trips when staying at hotels and this detector is easy to set up anywhere. The two pronged action is helpful since this vintage house has a mix of two and three. But for a trip the 9 volt battery is good to go.For RVers this is a must have. Even in a van camping. Better to be safe than sorry.Tip: Write the date of install in permanent marker on the face. This way no need to remember.Tip 2: Same with smoke and fire detectors. For those , what I do is write the yr and month the battery is changed every time. Thin permanent marker should leave plenty of room.Unless hardwired and in ten you just emplacements it. Still, add the date of install. Same with fire extinguishers. Doesn’t hurt to have the fire department inspect it periodically.I know people who’ve lost their hem to fire. Not fun. I know people, like myself, a CO detector got us outta the house.What I like about this detector is the directions have great specifics for set up to avoid false positives and a freak out. Yeah, I did. It was scary. Thank goodness the two times it was for real we were safe.Though at that time we didn’t have a level readout. That’s what makes this gem such a peace.Not sure how long the sale is for. But the singles are a great price now. Hope you score a savings, too.Hope I never hear these defectors go off. But I feel save knowing new ones are in place every ten or less years, if your renovating, where to restock 😊

Good news bad news
Worked as advertised. Warranty was 10 years and it lasted a little more than 10 years. Good news is it never detected any carbon monoxide. Bad news that meant I didn't need it.

Carbon Monoxide Protection for your Home
I purchased the Kidde Carbon Monoxide Detector for my home to replace another unit that had expired. The Kidde Detector plug-in design with a 9-volt battery backup is very convenient & easy to use. It offers continuous protection even during power outages. The digital LED display clearly shows CO levels, which is helpful for peace of mind.Unit came ready to use, with battery already installed. We just pluged it in and it was ready to use. We feel confident that our family has chosen a great carbon monoxide detector for our home.

Peace of mind for our growing family
I bought this Kidde carbon monoxide detector because my wife is pregnant, and getting ready for a baby has made me think a lot more about safety around the house. I wanted something simple, reliable, and with a digital display so I could actually see readings instead of just relying on an alarm.Setup was straightforward — plugged it in, installed the backup battery, and it was ready in minutes. I like that it has a digital screen and peak level button since it gives more information than basic detectors. The battery backup is also reassuring in case power goes out.The size is reasonable and it doesn’t stick way out from the wall. Alarm volume seems loud enough to hear throughout the house.I can’t speak to long-term durability yet, but first impressions are positive. If you want a straightforward carbon monoxide detector with a display and battery backup, this seems like a solid option.

Nice
I like that it's not battery reliant, but has a backup battery. I have a CO monitor diwnstairs, but feel better also now having one upstairs. If the diwnstairs monitor hoes off and this one doesn't, then I'll know that either the CO hasn't reached upstairs (unlikely) or this monitor doesn't work. Hopefully, I won't have to find out!.
