Since hurricane Irene I have become more worried about my sump pump not working without any power. I also have a refrigerator that is on a circuit that pops the breaker two or three times a year. I was looking for a cheap alarm to tell me when I have no power to the frig and an alarm to wake me during a storm so I can get my generator going to power my sump pump.
I really like that the alarm also subs as a flashlight when the power goes out. It has a built in rechargeable battery that powers several LED’s to make for an effective flashlight. The flashlight turns on automatically when the power is disrupted. The manual states the battery can run the flashlight for up to 6 hours.
The only negative is the alarm itself. It is not very loud. The manual says it is 78 dB. It is not nearly as loud as a home fire alarm for example. I plan on using one in the bedroom which should wake me if the power goes out. This alarm costs under $15 dollars. It’s a decent solution for the price.
