    Excellent UPS Works Flawlessly During Power Outages

    My go to for UPS supplies. I have several of these units protecting my most important electronics. I have used these extensively during power outages and I can say with confidence that they will not only protect your electronics, but also keep them running for a brief time. These are not meant to power your whole system for an extended amount of time. This is only so you can safely power down your devices.Another great feature of this device is that when the internal battery reaches its end of life, replacing it is extremely easy. It’s as simple as buying the battery and installing it with onl

    It works as expected.

    Great little UPS I like that it shows a battery charge level on my computer its about the size you would expect for a ups and for those who dont know what size that is about like a fat shoe box that is heavy that is actually pretty good.It works. No issues, and easy setup.

    Protect yourself before disaster.

    I had a previous cyberpower ups without a screen and for some reason the battery stopped working and a breaker flipped and my computer went out the second the power did which didn't make sense until I realized the batters couldn't hold a charge after 7 years. My pc started having problems after where it wouldn't take my old Ram overclock of 6400mhz now I can only go to 6000mhz without getting constant bsod.I upgraded to this for the screen and the outlet layout. I don't like the tower ups because the outlets are too close together while this one lays on the ground flat and has space for bigger

    It served well, but it couldn't handle my new gaming rig.

    Which makes sense, pay attention to the wattage rating on here. A good rule of thumb is find something that matches your PSU (power supply) on your PC. It's a little more nuanced than that since your computer isn't likely to be pulling the maximum wattage your PSU handles unless you're under a heavy gaming load. But if you're heavy into gaming it's a good rule to follow nonetheless.I just got a rig with the Nvidia RTX 4090, and when I got into some games that put that video card to hard work, that's when this battery backup got angry. Just one solid nonstop tone that doesn't shut up is the sig

    A few outlets that are uninterrupted so look for them on the outlet area. It’s well marked

    Works very well . It is used to keep my ccvc camera system and my cable company router powered during power out until my generator kicks on .. also works well here in Florida with storm fluctuating power loss . Power goes out for 4-10 seconds and internet drops until it reconnects takes a total of 10 minutes for the router to com back on . This fixes the issues and also tells you the amount of load on the battery and how long it will power what you have plugged in. Great battery capacity and easy to read bright display

    I was so excited 😊

    I love it . You can't use it for anything extra, but if you need backup power for your home entertainment, this is the way to go

    Created a new SOP...for insurance reasons

    Plugged it in to allow it to charge before using it, as instructed by the sticker on the front of the device. That's where everything went wrong. The display came on, after a few seconds it made a "pop" sound then immediately making a high pitched whining. The display was flickering on and off, I frantically unplugged it. After unplugging it was still making the high pitched whine. With it setting on my desk now concerned how much time I had before this thing was going to spontaneously combust, I made the decision to attempt disconnecting the battery. Flipped it over to be greeted with a screw

    I am sold on this brand

    When I added another unit to my mesh router system, I realized I also needed a new UPS battery backup. I hate it when even a momentary power outage causes my network to shut down and reboot. Living in a rural area, those brief outages happen more often than you might expect.I already own four other CyberPower UPS units that have performed very well, so choosing this one was an easy decision. Another advantage is that all of my CyberPower units use the same replacement battery, allowing me to keep a few spares on hand that will work with any of them.This UPS is completely silent during normal o
