    A very well made and solid device. It worked, as instructed, perfect the first time it was powered-up and has done so for several months now. Twice, when the power at my residence went out, it protected my expensive desktop computer and monitor; no interruption to their operation at all. Very recommended indeed!

    Unit is reasonably priced and has a number of well-spaced outlets. The hard thing about writing a review on a UPS is that if it works well you can't really write about it until its needed, and without a power outage so far I don't, but for a short-time, low capacity application this works well

    This is a great little battery back up. I personally have four different power supply back ups, running various items in the house. We have multiple larger battery backups, running the PCs and monitors. We also have battery backups on the fiber, Internet as well.

    I should've purchased one of these a long time ago. I has already been tested. Held power with no issues. I was able to save and exit what I was doing with no power loss to the computer I was on.

    10/10 recommend, saw it on a YouTube video and got it, ever since my pc, xbox and monitor have been plugged in and has saved them a couple time after my house lost power like 3 or 4 times in a row, they stayed on a I just made sure to turn them off, also there’s an alarm that let’s you know if something is wrong

    Read the instructions and you’ll be fine. I bought to keep my internet up and running during surges/momentary power outages and these work fine. I use the surge-protected outlets for other expensive items, but I have one of these for my modem on my demarcation wall and another on my primary router. So far so good.

    It’s performing as advertised. It has already proved itself in a power outage. I have this one powering my modem and router among some other items. I’m planning on buying another one for my main desktop.

    i am a firm believer that anyone using a desktop computer should have it plugged into a UPS. especially when you can get one of this quality for so cheap. Will save hours of work in the case of an untimely power outage

    My old UPS died, and it was time for a new one. This has the same rating but is less than half the physical size. But the important thing is that it works. It keeps my home office equipment running through the power blinks that are common where I live. (Above ground electric service with lots of overhanging limbs that do not seem to get trimmed often enough). I'm not sure exactly how long it lasts, I have not tested that, with my work laptop, docking station and two monitors. But I know it has lasted the 10 minutes I waited before I decided to shut things down.

    This CyberPower 450VA Battery Back-Up System is small enough to fit almost anywhere, and safely expands how many outlets are available. Four backed up "supported" and four surge protected outlets. I've looked everywhere and you can't beat the value of this little black box, in fact I've purchased several and have installed them throughout.
