Customer Ratings & Reviews

This model has plenty of outlets for heavy duty and light weight products.

This is a must have if you lose power at your house. You can plug in your internet modem and have internet during your loss of power at home. Modems don't use much power and it should last a while depending on how many things you have plugged into the power strip.

I purchased this Cyberpower ECL850LCD UPS based on the reviews I found on bestbuy.com. Having previously owned only APCC branded UPS, I was a bit unsure how this would perform. Eight months later I'm still pleased with the purchase and would recommend this to anyone who is in need of a UPS. It seems to be very sensitive to power spikes and is quick to respond.

Last battery back-up failed so I needed a replacement. This one has lots of electrical outlets to plug everything in. Works as advertised. Love Best Buy for customer service. They connected me to the right product to solve my problem.

Works as advertised. I have mine connected to a piece of equipment that draws a lot of power. It lets me know through an audible warning that it was to much of a drain on it with other device connected to it. So I moved some devices that did not need the ups. Works fine after that.

Good UPS!!! Easy to set up. I have it over a year now. And still works great. I bought it because it has "ECO mode" When the computer is off or is in sleep mode, the UPS automatically cuts power to computer peripherals connected to the 3 ECO outlets.

Works very well when there is a power outage. I have it connected to a circuit that sometimes trips and this has been great at keeping it alive long enough to flip the breaker.

Good system, but sporadic problems with backup working.

I bought this primarily to keep my security camera running even on power failure. I live in Florida and hurricane season will be coming soon, so I am expecting power surge power interruption. I am expecting this will work as expected.

So far so good. Haven't had a chance to see how well it works after a power outage. Very easy to set up and lcd display is nice to monitor capacity and usage

This UPS is providing power to a PS4, and DVR. So far I have not had any power failures, or surges but the unit appears to be operating as designed. Compact size makes this easy to place in tight spaces.

This become essential at home. When power outage, you have to make sure your security, alarms, cameras are all working. The product serves exact the purpose. Recommended.

just wanted a little something to keep the internet up during the annoying brown outs weve been getting, does the job.

Performs as expected. I have several power blips and it has not failed to provide continuous power to my electronic components

this is an updated version of one that i had.... just perfect for my computer and acc. and phone charger is a plus!

Works well and has plenty of plugs. The eco plugs are a great addition. Already had to use it during a power outage and it stuck it out perfectly.

CyberPower UPS's have been notoriously unreliable (some lasting only 2-3 months), but they are much cheaper than APC, so I keep buying them. We'll see how this one goes. However, I decided to get a replacement battery for the last unit, and while I was at it, checked for this unit, and found out that this unit's battery is not serviceable. No "green" corporate ethics here!

Looked on line for a UPS, reviewed all the options choose a couple then went on line to Best Buy and ordered the one i wanted.

CyberPower - 850VA Ecologic Battery Back-Up System - Black is good backup power

I love the digital interface of this product. It gives it character and allows me to see how well the product is functioning.
