Many also appreciate its affordable price, ease of use, and compact size, with several noting the convenient number of outlets. A small number of users mentioned a noticeable humming sound when the unit is running on battery power, and the lack of a USB connection was also cited as a drawback by a few customers.

    I needed a battery backup/surge protector in my attic to protect my computer modem and water softener controller. This did what I needed.

    I am happy with the Cyberpower UPS. It has prevented loss of power of key hardware and did not allow any surges to get through.

    We live in the High Country and power surge protection with power outage defense is critical. This is the one.

    Every time we would have the slightest storm in my area, my phone and computer would go out and not come back for quite awhile. Dear AT&T finally came out and realized it was caused by a wire outside my house. They fixed the problem, but the technician suggested I get a battery-backup surge protector that included a "phone line" just in case, so I did. Luckily, I haven't had a storm since I installed it, but I feel better knowing I have this surge protector in case I need it.

    I have been using the cyberpower products for over 10 years. I have found that when it comes to any issues with their products they stand behind them 100% And if there is an issue they will replace it without question immediately. You don't have to go through a testing process in order to verify whether the product has failed or not. And they always make sure that they you are getting the best for the product that you were looking for at the price that is best for you
