Power Failure Alarm for Freezer, Briidea Power Outage Alarm with LED Indicator Lights and 80-120dB Adjustable Alarm, Perfect for Monitoring Refrigerators, Freezers, and Sewage, MK-077

Simple to use and reliable. Immediately alarms on outage. Works anywhere along the circuit you want to monitor if you can’t plug the device directly into it.

Works exactly as expected. The alarm is loud enough to hear from the basement but not too loud.

I have this on my garage fridge so if the GFCI breaker trips, I'll know. So far, it has saved my twice. THis is a great product for a great price. It is super loud so you will be able to hear it no matter where it is.

The media could not be loaded. Its loud enough and it works as described. I tripped circuit breaker and it went off. My mistake i thought it also sensed a “ load “ plugged into it and would alarm if a plug falls out ( refrigerator/ sump pump) but it just tells you if it has power to the outlet its plugged into. Which is fine for the money. No App or Wi-fi connection so it does you No Good if no ones home. Also depending on how long it was alarming it can take up to four hours for it to recharge.

Great product, has alerted me twice since installation. Both times power was restored but could have been a problem. Very loud. Well worth the cost!

This gives me the peace of mind that my freezer in the garage is running. I've had issues with the breaker tripping but not having anything noticable on that circuit it would be a long time before I realized it was off. Now this alarm goes off and I can hear it anywhere in my house. No more worries with thawed food! Highly recommended!!

Works well so far no more defrosted spoiled food.

Loud alarm, sounds like a soke detector going off! Very easy to use and has already alerted us once for power failure when the GFI tripped for whatever reason. Well worth it if it saves the fridge contents paid for itself already
