This UPS lacks quality options, but it really has plenty of stores and delivers enough ability to keep a home Wi-Fi community up and functioning for as long as an hour or so and a half when the power goes out.

It provides sufficient surge security. Within our testing, the CP900AVR knocked down our five,000-volt surges to just 540.4 volts.
