Hendun Upgraded Power Failure Alarm, Gfci Circuit Failed Dector Alerter, Smart Outage Reminder For Freezer In Garage, Monitor Cut Of Cpap, Breaker And Gfi/Gfci Trip Alarm

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 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!!

Fácil de instalar y usar bien volumen y varias opciones de alarma.

These little power outage gadgets are awesome! They're the only model I could find that allows you to use regular AAA batteries. All the other brands/models use rechargeable batteries which go dead in a few years, and then you have another item that needs to be recycled. They are loud, work reliably and have the buttons on the front to easily silence them in an outage. I purchased a huge bag of 14 of these units and every last one worked flawlessly. I'm using the Energizer AAA lithium batteries in these which have up to a 20-year shelf life. Since the power only goes out once or twice a year for only a few hours they should last a while. Also, they have a choice of alert tones to choose from that DO NOT sound like a smoke detector. You could get your home broken into by the fire dept if your neighbor calls them saying your smoke detector is going off. Not a problem with this alarm as the alert tones sound different and are intermittent.

Works just as described! Thank you
