Nice & Loud – definitely would wake me up if power goes down!
I find AC power is going down more often than it used to, partly because it is California and they have some protection built in such that if a power line gets hit by a branch or even animal it could cause it to shut down power to prevent triggering a wildfire. It usually stays down for at least 2 + hour, sometimes more.Several times I’ve been on the very of having a whole refrigerator and freezer’s worth of food spoiling so I ended up getting a 2 Kwh power station solely for my frig/freezer. Already had to use it twice in the last few months. During the day it is easy to know obviously when power goes down and I just go down and plug my frig into the power station.This little gem provides the protection if power ever goes down in the middle of the night while I am sleeping. It is nice & loud and would easily wake me up from even the deepest slumber. Well worth the investment and I highly recommend it.Only one con I would note. I’m not sure this would be loud enough if for example you are monitoring an outlet or device on the other side of the house or something. For me I just plug it into an outlet right in my bedroom because when I have a power issue the entire home is always affected.Suggest an enhancement where the main device can communicate with a wireless receiver and sound the alarm in the bedroom even if the monitoring device itself is on the other side of the house.Nevertheless this product is easily worth 5 stars.Update: on 6/8 AC power went down about 10:30pm when I was sleeping. This product indeed did its job well and woke me up from a deep sleep. Power was down until almost 4:30am and then was barely up for like an hour and went down again for another hour and a half. There is 100% chance my entire freezer and frig would have been full of spoiled food had it not been for this great product. Wish I could give this 10 stars!!

Amazing Item
I’m blown away by the Hendun Upgraded Power Failure Alarm.I was skeptical at first, but this thing has been a game-changer for me. As someone who’s had their fair share of coming home to a dead fridge, I can confidently say that this device has saved me from more than one potential disaster. It’s ridiculously easy to set up and the smart alert feature is super reliable. I’ve had it for a while now and it’s worked flawlessly, especially during a brief power outages. The fact that it can detect GFI/GFCI trips and breaker issues is just the icing on the cake. Highly recommend this to anyone who wants to avoid the hassle of a dead fridge or CPAP machine. Trust me, it’s worth every penny! I’m really glad I made the purchase.

So far, so good
Canât really speak as to how well the product works when the power does go out since it hasnât happened recently. Easy to start up and install. Alarm is super loud. Seems like it will work well if the power does fail. We bought this because our freezer in the garage is plugged into wonky plugs that go off without notice and nothing in the house is connected to the garage plugs so after power outages, we have lost so much food at least 3 times now. Hopefully it wonât happen again.Edit: power went out and the alarm went off! Works like a charm. 🙂

Continually trips GFCI
I purchased this to notify us if the power is ever disrupted to our water purifier. The purifier is plugged into a GFCI circuit. We’ve never had any issue with the GFCI tripping but wanted this alarm “just in case” as we’d not know that it’s not powered. About one day after plugging the alarm into the same outlet as the purifier it has tripped the GFCI multiple times, with nothing more than a VERY faint beeping — which couldn’t be heard unless we actually open the doors to the storage room where the purifier is located. Each time it tripped the circuit we reset the GFCI, and sometimes within hours the circuit would trip again. I had great hopes that this product would notify us of any outage — but it seems to be CAUSING outages in our situation. I might add that our home is new construction with all new circuitry, and we’ve never had any problems before this. Sadly, I can not recommend this product.05/2024 — I want to update my review. Even though I’m disappointed that this alarm isn’t working in our situation, I want to commend their customer service for dealing with the situation. Our home is brand new construction, with ‘smart/self-testing’ circuitry. So I don’t understand why our situation is unique. However, their customer service has been great.

A Must Have
This device has saved us money. We purchased this after a breaker tripped in our garage, where we have a fridge/freezer and deep freezer. We didn’t notice the tripped breaker until a few days had past since we don’t go out there often. I lost all of the food in the fridge and freezer. This device is perfect for alerting us to any tripped breakers or power outages. It has worked as described several times when the power was out. It is loud enough to hear through our door and walls if we are inside the house and in a room that is next to the garage. We can’t hear it in the back of the house, so if it goes off while we are asleep, we won’t know until we get up the next morning, but that’s OK. Even if we don’t hear it until the morning, the food will still be OK. It runs off of a rechargeable battery that charges itself when plugged in. I can’t recommend this enough for anyone that has appliances that may trip a breaker but not get noticed immediately.

Broke after 5 months – no support info
This product was working great for 5 months but now doesnât work. The parts that work off the battery donât seem to be working. Beeps every 30 minutes but doesnât alarm when electricity turns off. None of the buttons work either. I canât find any support info or warranty info.

These work great. We bought a second one after trying out the first, and they’ve already saved a fridge and freezer full of food.The alarm is nice and loud (you can choose among several and adjust the volume), and has always worked as expected, both in testing and in an actual power failure.The icing on the cake: if you use rechargeable AAA batteries, the unit charges them itself. Any modern device like this should do this, using consumer-replaceable rechargeable batteries, but before purchasing this one we were using an older unit that didn’t.We’re using these alarms on two GFCI outlets, one with a fridge/freezer combo and one with a chest freezer. GFCI outlets are notoriously troublesome, and before we put alarms on ours, we lost a chest freezer full of food without being able to repeat the issue or find the cause of the tripping.These alarms are the answer.

I got this for my saltwater reef aquarium so that if the power goes out at night I know immediately. It worked perfectly during the last power outage.
