Battery capability: Company run-time rankings define how long a UPS can retain devices of varied wattages functioning. Because most rankings are dependant on best ailments, we tested our prime candidates at two distinctive loads to find out how they might perform in actual-earth use: twenty W, symbolizing the combined electrical power draw of a family modem and router, and 300 W, representing the power utilization of the modem, router, Computer system, and exterior disk drive managing concurrently.
It offers excellent battery lifetime. The CP900AVR surpasses most products we analyzed in operate time.
