Power Failure Alarm 2 Pack - 110dB Power Outage Monitor with LED

In this review the Power Failure Alarm 2 Pack is evaluated for homeowners and small business users who need a reliable, easy-to-install alert when mains power is lost. The single biggest reason to buy is straightforward: it provides an audible 110dB alarm plus LED notification and a rechargeable backup battery that will continue cycling alerts for up to 12 hours, giving you time to protect food, equipment, or systems. The reviewer found setup simple and the multiple tones and volume settings useful across different rooms and appliances.

Key Features

• Power outage alert: Emits a combined 110dB siren and LED flash for 60 seconds immediately after a detected power loss to draw fast attention.
• 12 hour backup: Built-in rechargeable battery keeps the unit cycling audible and LED alerts for up to 12 hours, so you are warned even during prolonged outages.
• Seven sirens and volume control: Offers 7 ringtone options and a 5-level volume control from mute to 110dB, letting you tailor the alarm to location and tolerance.
• Auto and manual cancel: The alarm stops automatically when power returns or can be silenced immediately with the cancel alert button for convenience.
• Integrated socket: Appliances plug directly into the alarm, so it monitors the circuit without occupying extra outlets and still allows normal appliance access.

Who It's For

The Power Failure Alarm suits homeowners with freezers, refrigerators, sump pumps, aquariums, or furnaces who need clear audible and visual notification if mains power fails. It is also appropriate for small shops or server closets where rapid awareness of loss of power can prevent costly damage.

People who should look elsewhere include those who require networked remote notifications (text/email) or battery-only portable alarms, since this model focuses on local audible/LED alerts and plugs into the monitored circuit rather than offering remote alerts.

Pros & Cons

Pros

• Clear, immediate 110dB alarm plus LED flash offers unmistakable local notification.

• Multiple siren choices and 5-level volume control give practical flexibility for different settings.

Cons

• No built-in remote notification feature; alerts are local only.
