## Description

Satisure Plug in motion sensor

Review: Reliable and Easy-to-Use Power Failure Alarm with Adjustable Alerts - 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 monitoring 12-hour alert feature prevents constant ringing Versatile for use with freezers, refrigerators, sump pumps, and aquariums Easy setup and user-friendly Cons: Requires a plug-in (no battery backup) Limited temperature sensitivity settings
Review: Great item, especially when the power goes off at a critical time. - It works well. I got it because I hatch chicks in my incubator and every time there are always a power failure that happens in the critical time of incubating. And always at night when I am sleeping. Most of the time I only wake up an hour after and the temperature of the incubator has already dropped and cause many chicks to die. With this item, I have it in my bedroom and when the power goes out, I can rapidly go and engage the emergency generator. Also you can choose among different chimes and especially you can adjust the volume. This way you can adjust it loud enough to wake you up but not to jolt you out of the bed. I wish I had bought this item years ago.

### ⭐⭐⭐⭐⭐ Immediate alarm on power outage, choice of alarm tones and volume level.
*by M***Y on 23 February 2026*

Very effective and useful alarm. Alerts immediately when power goes off - essential if you have a generator, as we do. We need this to alert us to a switchover to the generator, so that the main house heat can be turned off, so as not to bog the generator down with too much amperage demand. The other nice things about it are the ability to modify the volume levels, so it doesn't blast your ears off (like some smoke detectors), and a choice of alert sounds. The replacement outlet on the front of it is the icing on the cake. Just plug and play.
