Full listing title: Kidde Carbon Monoxide Detector, Plug-in Wall with AA Battery Backup, Test-Hush Button
Rated from the listing's specs, no buyer reviews yet
What it's made for: peace of mind on outage nights.
Two CO alarms close to it on our rating, each with a dated price.
It plugs in with a battery backup, per the listing, so it keeps working while the power is out, which is exactly when the generator runs.
Put one on every sleeping floor and one near the door closest to where the generator sits. Push its button once before storm season and listen for the beep.

Want smoke and CO in one unit? The Kidde AA Battery CO Detector (7.4/10) is a combined smoke and CO alarm.
Our take
The Kidde Plug-in CO Detector is about plug-in power with battery backup, and it doesn't pretend to be more. No buyer reviews yet, so the Kidde Plug-in CO Detector has to win you over on paper. Where it falls short: one alarm is not a plan; you want one on every sleeping floor. We'd pick this Kidde CO alarm if you run a generator anywhere near the house; otherwise, put it next to the Kidde Portable CO Detector (3rd Ed.) first.
Before you order the Kidde Plug-in CO Detector, check where it will go: it plugs in with a battery backup, so it keeps working during the outage; place one near the door closest to the generator.
Find the full model number on your generator's label and compare it with the listing before you order.
One on every sleeping floor and one near the door closest to the generator. Our CO safety and placement guide covers placement.

Both score 6.8/10. Compare the listings side by side to choose.
We rate it 6.8/10 (good). The rating comes from its documented listing alone, as no customer-review record is captured yet.
Only if your generator manual confirms it. Check the outlet or plug type, the amperage, the list of supported models and any adapter the manual asks for; looking similar is no proof that it fits.
Its listing states plug-in power with battery backup. These are the seller's figures, not our measurements: whether it fits your exact generator is worth confirming first.
