power loses over night it wakes me to call power company.

It works. Loud enough to wake me up on other side of house.

I can’t tell you anything about it because I just got it and haven’t used it yet. If you check back later I can give you a better idea.

I used a certified dba calibrated meter and the loudest of any alarm tones is 82dba at 3ft away.

We bought this to alert us of power failure in a garage fridge. It was super easy to set up and did exactly what we wanted!

This is one of those things that you don’t know how good it is until you need it. I have a sump pump and a freezer plugged into 2 gfi outlets in my basement. Recently there was a blackout for a few minutes. When power returned the gfi outlets did not reset. The sump pump was off and it rained, leaving me with a wet basement floor. I bought these devices to prevent that from happening again. I haven’t tested them. They just plug into the outlet and the indicator light comes on. You plug your appliance into this device. It rings if power is cut to the outlet. This only takes up one outlet on a duplex box so you can use the other outlet for another appliance. I am satisfied with this purchase.

After having our outlet trip during a power failure and losing hundreds of dollars worth of meat and food in our deep freeze, we turned to this product. Since installing, our breaker turned off again during a storm and the alarm immediately sounded. Even though our deep freeze is in the garage, we could hear it inside the home. Simply plug it in, plug in your appliance and it’s all good! Best purchase in a while

This power failure alarm does the job, but it has a few drawbacks. The alert sounds aren’t very loud, which could be an issue if you’re not close to it or have a loud TV or music playing. Additionally, the selection of sounds feels a bit odd and not very practical for something meant to grab attention. That said, it’s still helpful for monitoring power outages and does work as advertised. Overall, it’s a good product but could use some improvements.

I’ve been using the Power Failure Alarm for my freezer and refrigerator, and I’m really impressed with its functionality. It provides peace of mind knowing I’ll be alerted if there’s a power outage or temperature issue with my appliances. Here’s a breakdown of my experience:What I Like:Adjustable Alarm Volume (0-110 dB): The adjustable volume feature is fantastic. Depending on where I place it (in a loud kitchen or quieter pantry), I can set the alarm to a level that’s just right. The 110 dB is LOUD enough to be heard from another room, but I can tone it down if needed. It’s a huge relief to know I’ll hear it, even if I'm not in the immediate area.Clear LED Indicator: The LED indicator is a really nice touch. It lights up when the alarm is triggered, so I can easily see the status at a glance. The color changes based on the alert level, which makes it easy to understand whether the power is out or if the temperature is outside the desired range.12-Hour Alert Function: I like that the alarm has a 12-hour timer before it resets, so it doesn’t keep ringing non-stop once an issue has been detected. This gives you a window of time to address the issue without being overwhelmed by constant noise, and the alarm automatically resets if everything is back to normal.Versatile Use: I’ve used this alarm not only for my freezer but also for my refrigerator, sump pump, and even the aquarium. It’s a versatile device that works in various situations, and it helps to monitor power loss or temperature fluctuations in different appliances. This gives me confidence that all of my sensitive equipment is being monitored effectively.Easy Setup: The setup is super simple. I just plugged it in and mounted it in a spot where I can hear it clearly. It comes with an easy-to-understand manual and instructions, making it very user-friendly.What Could Be Improved:Not Battery-Powered: One thing to note is that this alarm requires a plug-in to operate (it doesn’t run on batteries). While this isn’t a dealbreaker, it does mean that if there’s a power failure for an extended period, the alarm itself will go off, which might not be helpful if the power outage is widespread and the device itself loses power. If you’re looking for a more portable, battery-operated option, this might not be the best fit.Sensitivity Settings: While the alarm works well for both power failure and temperature changes, there isn't much adjustment for temperature sensitivity. It might be nice to have more control over the specific temperature range at which the alarm triggers (like allowing it to activate only if the freezer temperature rises above a certain threshold).In Summary: The Power Failure Alarm is a fantastic tool for anyone who wants an extra layer of protection for their appliances. It’s easy to set up, versatile, and provides reliable alerts for power loss or temperature changes. I feel much more confident knowing that my freezer, refrigerator, and other sensitive equipment are being monitored 24/7. The adjustable volume and LED indicator make it very user-friendly, and the 12-hour alert feature is a thoughtful addition. My only minor gripe is that it’s not battery-powered, so it’s not ideal in situations where power outages last longer than a few hours, but for most uses, it works great.Pros:Adjustable alarm volume (0-110 dB)Clear LED indicator for easy monitoring12-hour alert feature prevents constant ringingVersatile for use with freezers, refrigerators, sump pumps, and aquariumsEasy setup and user-friendlyCons:Requires a plug-in (no battery backup)Limited temperature sensitivity settings
