But the batteries can only power the essential items in our house for a limited amount of time. A lot of our essential circuits have other items plugged in, and we need to marshal the amount of power usage to insure we don't run out of battery power. We put this alarm on one of the outlets that does not receive power from our battery backup, since the batteries take over seamlessly during an outage. There is a red flashing light, which is quite bright, and a VERY loud alarm that goes off when the outlet looses power. This lets us cut off not essential items, check the amount of juice we have in the batteries so we can manage our use. It is a great tool for people with systems like ours. Review: Fast install and solid basic functionality - Simple to use. Plug it into an outlet turn it on and if the power fails the alarm goes up. It cost effective way to monitor power near freezers and other places where lots of power could be a problem. Decent build quality. WiFi connectivity would be a plus. ## Features - Function: Alarm for both power failure and come back, different alarm voice for power off and on. - 118 dB: 118 db loud siren that keeps the alarm until it is turned off or the battery is exhausted. - LED Light: Led flashing allow you to see the alert even from far away.

Plug it into an outlet turn it on and if the power fails the alarm goes up. It cost effective way to monitor power near freezers and other places where lots of power could be a problem. Decent build quality. WiFi connectivity would be a plus. ### ⭐⭐⭐⭐ Really, really loud *by J***R on September 1, 2022* The alarm works well. My only complaint is that it is too loud. We want to know when we lose power to our refrigerator. It doesn't need to sound like we are under attack by Martians! I had to cover it in a piece of foam rubber to dampen the noise. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/395980049-qwork-power-failure-alarm-118-db-loud-siren-with-led](https://www.desertcart.hr/products/395980049-qwork-power-failure-alarm-118-db-loud-siren-with-led) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-20*
