Considering that most rankings are dependant on suitable conditions, we analyzed our top rated candidates at two diverse loads to see how they might perform in real-environment use: 20 W, symbolizing the merged electricity draw of the residence modem and router, and 300 W, symbolizing the facility utilization of a modem, router, PC, and external harddrive running concurrently.
It offers terrific battery daily life. The CP900AVR surpasses most designs we tested in run time.
