    Great UPS for the price. I bought my UPS for home use with two laptops and a 21-inch monitor. 1. Great looking, with low noise, with plug and play capability. 2. AVR (automatic voltage regulator) extends battery life and smooths out voltage spikes. 3. Green On/Off power light indicator lets you see at a glance if your system is on or off. 4. There is also a mode button that lets you cycle through several different status indicators such as, Load Input, Run Time, Load Capacity by % and Battery Capacity by %.

    Going Strong 1 Year Later

    This battery backup is still going strong after 1 year. Supports my mid-range gaming desktop, 34" ultrawide monitor, and projector without overloading. Includes useful Windows 10 software enabling me to test functionality and set time automatic shutdown. I was initially worried that that my computers power supply (Corsair RMX750) would only support a pure sine wave battery backup. Glad that's not the case :-)

    The item is easy to use & will hopefully keep my NVR running during power outages. I only wish the instructions were easier to understand, but my equipment is currently plugged in & all appears to be operating appropriately.

    Just what I needed. The electricity in my bedroom would often cut out for a split second, causing my computer and ceiling fan to shut off briefly. This has more than enough power to keep my gaming computer going. The settings can take some getting used to, and it will make a loud beeping noise when the power goes out, but you can mute it.

    dependable battery back up system

    I've recently experienced my 4ht black out in Sherman oaks and feltb it was time to have a battery back up ...just in case. DSo, I purchased CyberPower -1000 and tested it out. I conveniently killed the poser to the house and relied on nothing but the battey back up. amazingly enough it worked. It gave me power where I needed it for up to 6 hours roughly. I didn't power everything, just the things I felt relevant (radio, tv, computer, cell phone, lights in the area i was occupying). in a nutshell, the Cyberpower 1000 did its thing. Very happy

    CyberPower - 1000VA UPS - Good value

    Best value for the size. Looked at several others that were a little larger than 1000VA but the cost was a lot higher. UPS used for a network rack rather than using a $400 rack ups. POE wireless APs, switch, router and cable modem have a 72 minute run-time. This unit also filters the power, not all UPSs have that capability.

    Needed a flat battery system for my den, and the ones I like from APC are tall. I know I can rotate them but then I can't see the indicator lights. This one is just the perfect size and works well and there are plenty of plugs, which is critical for the den. I usually buy APC products but I will consider more CyberPower products in the future. Great product.

    Bought this to replace a several-year old APC unit that quit (battery was OK, but it didn't keep things running when the power went out). Apparently APC doesn't make theirs with mounting holes on the back anymore. That was a deal killer. The CyberPower unit kept things up and running during a recent thunderstorm and 20-second power outage.

    We have storms around my area often. I bought this so I could safely power down my Computer and safe any work that was currently being done on it at the time. Gives me about 30 minutes to do what I need to do after power goes out. Useful item. Has a god awful beep that reminds you that you are using battery power.
