Customer Ratings & Reviews

After charging this unit for the suggested eight hours, I plugged in most of my entertainment devices into the power-backup outlets, including TV, sound bar, Blueray player, cable box, cable Internet router, and an extra router for home security. I then turned on the unit and all of the above devices, and set a DVD to start. All of that registered as using only up to 20% of the battery power available, for up to 15 minutes. I later went to my circuit breaker box and turned off the power to that area of the room several times, and the unit worked like a charm, keeping everything on even with no lights. Granted, the unit has an extremely low joules rating, compared with normal surge suppressors, but I have a full-house surge suppressor, so I'm cautiously confident. Also, the LED panel is easy to read and figure out. So far, I'm very pleased!

Price is what sold me on this and the features that won the fact I purchased

I live in Fl. And we get a lot of power surge espcially during a storm. This product will help you keep the wifi running even during a black out. I use the battery for my modem router and security devices. Works great espcially the LCD multifunction screen so you will have an idea how much battery % left for the back up. This is much lighter in weight than the other 850VA without the screen

Price and sophistication of UPS's have each improved since the last time I've purchased. The capacity is nice ampere-hour wise, and the lcd readout yields useful information. Output voltage and time remaining are among the most useful. Startup and shutdown is quicker than my last units.

This power source backs up my office in Washington, D.C. That has approximately 10 employees. I have the server and router plugged into this source and it has done a wonderful job in case the power goes out. The beeping sound alarms you but is not overbearing

Kept my PC on during a power surge. I believe my PC and monitor use a calculated 380W under heavy load. The price was a bit high and I was upset to find a better model on sale a week after I ordered this, but oh well.

Works great! Power to my house has went off a few times and this device has kicked in to keep my computer up, giving my time to shut it down.

Previous to this, I had the CyberPower 650, which left me pretty satisfied. It lasted over 7 years, even though I was told they lasted about 3-5 years. Before that, I'd had another well known brand that was good, but whenever our power went off, its back-up reaction wasn't quite fast enough to keep the DishNet receiver from rebooting! So, when I got the CP650 and discovered that it saved the receiver from rebooting, I knew which brand to go for the next time! This time, I went for the CP850VA because it could handle more power and it also has more inputs. Another well known place had it for cheaper, but used Best Buy's price matching to get it for the same price and BB's delivery was several days faster (plus, they're better for getting tech help). There was a brief moment of power loss about a week ago, so I've already seen it kick into action (with no Dish receiver problem). Actually, my 650 has been put to new use, but in another area with less of a load for it (the old battery is now a bit too weak for my AV setup, but still able to do much of its thing)! The 850 is actually more than I need, but possibly it will last even longer before the battery weakens enough to become a problem! Might have to wait 7 years to find that out, though. :-)

The LED display is why I bought this.Having all current information displayed works great! There is also a nice "beep" whenever you turn (off or on) the system. Easyto use , easy to setup, and does not take up much space(small footprint).

This is one of the few surge protector/battery back ups that had 12 usable plugs. And properly spaced so that different sized plugs can fit. I would buy this product again. I feel that the quality of CyberPower has gone up while APS may have declined.

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.

Great piece of equipment, easy to use, reliable, and pretty cool looking.

I have one of these for my main computer and one for my home server. The software is extremely straight forward and easy to use and the desktop widget is a nice addition. The widget can be customized to show real time information in a number of ways, including how many watts are currently being used by the system. I've only had them for about a month now, so I'm not sure how these will last, but so far so good.

My house went dark once while I was in the middle of project and I did not have a UPS. I lost a lot of data and had to rebuild my project from scratch. That is why I believe a good UPS for my desktop is essential. I've owned several Cyber Power UPS systems and trust them to give me the time I need to save my work during a power outage. I recommend Cyber Power because It is reliable and economical.

So far this UPS has been working great for me. I'm very happy with the purchase.

This was the perfect Surge and Battery Back-Up System all-in-one. It was purchased specifically to be used only with a new Samsung QLED 55" Television and Samsung 3D Surround Sound Bar, and Wireless Samsung Woofer and some other items associated with this system. My building has very good electric current regulation, however, there can be occasional small "spikes" or "surges" and/or loss of power for a minimal time. This keeps the power smoothly flowing to my entertainment system, even with an occasional spike/surge in power; plus, gives me more than enough time to turn off all devices if power goes out momentarily. Highly Recommend.

Has a lot of outlets for what you will need on a home office too !

Used this one in particular for several devices at one time. After a few weeks, and having it charge for about 24 hours, it has been working just fine. Apple tower, screen, scanner and printer all connected with no hiccups. Occasionally, will connect a phone charger. I have never had everything activated or working all at once, that may not be recommended unless its higher than 1,000VA, in my opinion. Overall, very good and dependable. This is my 5th I've purchased for the office spaces.

This is the second unit I've purchased in the past few years. I previously purchased one for a setup in the master bedroom.We tend to have momentary power outages in this area during the summer months due to thunderstorms. When this happens all the electronic equipment resets including my 4k television and cable tv box. The reset can take up to an annoying 10 minutes, and then 5 minutes later it might happen again. This ups, which I installed in the living room, keeps power to these units preventing a reset.

Easy setup. The only thing to watch out for it keep in mind the size make sure it will fit where your going to put it.
