Customers are saying

Customers admire the 1000VA Battery Back-Up System for its exceptional battery life, overall performance, ease of use, and surge protection capabilities. Many appreciate its compact size, reasonable price, and the abundance of outlets it offers. While some users have noted that the device can be a bit noisy when activated and slightly heavy, and that the instructions could be clearer, the positive aspects appear to outweigh these concerns.

    It does its work. I needed to replace my old UPC. This one is much smaller than the one I have and works fine. I like how it has half of the outlets connected to the battery and half not connected to it.

    Cyber Power did pretty good job with this unit, for the money! So far So Good. Buy the warranty, Units last about what's printed on the box ! You will have plenty of time to shut PC down if your there during a power outage!

    UPS with surge protection helps smooth out power hits and brownouts preventing premature equipment failure. Has power meter, voltage from utility, and frequency are displayed.

    One of the better battery backup for my computer system. Has never needed a reset and maintained my system for 60min following a power outage. A bit expensive but a great buy.

    So far I have not had any power loss events but I'm sure it'll be fine. I'm just powering a NAS so it should last long enough to shut it down. I'll update this review if it doesn't.

    The UPS is my second with the first one lasting at least 5 years before it failed. Customer service was helpful in identifying that the error code was NOT the battery and the unit itself. I gladly bought another and when the new one was hooked I took the old unit back to Best Buy for recycling as I have done with other electronics in the past . . . and they said they could not recycle it because it had a battery! I was miffed and highly disappointed that Best Buy sells products they will not assist in taking out of the waster stream when they reach their end of life.

    12 outlets, 6 UPS, 6 ac only outlets. There are 4 outlets spaced apart for larger ac plugs, 2 are UPS. Digital readout during surges, back up power if needed to power down your equipment during power blackouts. Good warranty. Great website and customer support.

    We have purchased Cyber Power in the past. We have found it to be a very reliable product. We liked the fact we could easily see each source we wanted to plug into this particular model. Good value for the price.

    Good UPS and Power Conditioning

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    My wife sews for her hobby and she is very good at it. She just bought a new sewing machine. The price was several thousand dollars. The vender highly recommended getting a UPS system that provided power conditioning to deal with lightning, spikes in the commercial power and general power problems that can cause immediate and long-term problems with the sewing machine. The CyberPower 1000VA seemed to exceed the minimum power specifications Pfaff. Plus it was just over $100. Just under 2% in additional cost to the sewing machine. I’m thinking of getting a couple of these for my computer and peripherals and the other for my media center. I just have everything on surge protection now. Power conditioning seems to be a good thing to provide.

    I bought this UPS for my high end gaming system since I was getting brown outs and did not want to lose power. Works great and I have had no issues. Bought it from best buy since I had some rewards to spend and it was a mid-range unit. Would recommend.

    This CyberPower Battery Backup does a great job of powering my DSL Modem and Panasonic telephone. The interface that tells you how many minutes of power you have left and the health of the battery in the unit are easy to access and understand.
