    i have my garage door opener plugged into this box in case of power outage. it was much cheaper than replacing the whole garage door opener with a newer one that had a backup battery.

    Won't know if it works until the power fails. But did test it by pulling the power cord. No reason why it won't work. Great for the price. The small KVA model is all I needed to protect the water softener.
