Because most ratings are based on ideal conditions, we analyzed our major candidates at two distinctive hundreds to discover how they'd complete in actual-planet use: 20 W, symbolizing the blended electrical power draw of the residence modem and router, and 300 W, symbolizing the ability usage of the modem, router, Laptop, and exterior disk drive functioning simultaneously.
It provides sufficient surge defense. Inside our tests, the CP900AVR knocked down our five,000-volt surges to simply 540.four volts.
