If the power goes out, chances are your garage door opener goes out of commission too - unless it’s plugged into a CyberPower Uninterruptible Power Supply (UPS) like model LE825G. The unit is designed to safeguard small loads, such as garage door openers, home entertainment systems, and office workstations in the case of a power outage.  For a garage door opener, the UPS would install on the garage ceiling and plug into the outlet where the opener would normally plug in. From there, plug the opener in the UPS for back-up power. For about $90, the unit offers enough power for a handful of full open-and-close cycles so homeowners and their vehicles won’t be stuck inside or outside during a power outage. The LE825G is recommended for use in temperature ranges from 32 to 104 degrees Fahrenheit. cyberpower.com
