    Works fine

    They seem much smaller then the old ones and lighter must have a new type of battery. This is only a 450. I only have a desktop and a wireless modem plugged into it.. If you put anymore into this unit you will need a bigger unit like a 650 or greater.. I have a 650 one for hurricanes to charge phones there great for this.. It will also power lights if needed or radios or laptops or tablets. Desktops take to much power they will run the battery down in no time. . Laptops much better or tablets.

    Dead Upon Opening

    I plugged this in and let it charge up (Needs to charge 8 hours before use) then I plugged in 3 monitors and my desktop so it was not fully loaded. Then it started beeping out of no where and the beep stood for the battery being overloaded. So then on the website it said unplug everything then unplug it from the wall so it runs off the backup battery and if it kept beeping for the battery being overloaded then the battery has malfunctioned. Upon doing this it kept beeping so I promptly returned it and got a regular surge protector.

    Good short term power backup

    When the storms come that knock trees into power lines, the electricity will frequently drop out for only seconds at a time. It wreaks havoc on fine electrical equipment. For a very reasonable price, this backup bridges the gap between the loss and restore of those brief outages. My particular use is for my UV water purifier for my well water. It prevents the early demise of an expensive UV bulb. The price of this backup is WELL WORTH not buying new UV bulbs all the time.

    Long power outages (5 to 13 hours) happen where I live as often as twice a month, and since we're in a dead zone for cell coverage we have to use wireless at home, so without power I don't even have a phone connection. This UPS is just right for keeping my cable modem, wired/wireless network and VOIP phone working during a long power outage. It's the kind of thing where there's not a lot to say about it. Either it works when you need it, or not. This works.

    I purchased this to be the battery backup for my Cable Modem. It works perfectly for this and should easily keep it up and running for 30-45 minutes if I lose power. I sadly lose power for 10-15 seconds at my home at least 1 every month or so and this makes things easier. I highly recommend this and would buy again. If you look I did... I bought this the 650 and the 1500 model for other uses in my house.

    Excellent Backup

    I love in an area that sadly has too many surges and this thing has outright saved my work on my PC too many times to count. The loud beep will let you know it’s served you, it’s intense, but I’ll take a little shock knowing my gear is protected allowing me to save and properly shut down. This has a 15 minute back up, so you have plenty of time to finish work and save. Worth every single penny.

    I have my NAS, router, and modem connected to this. 4 of the outlets are "protected" and the other 4 are running from the battery. These 4 battery operated are the ones that stay on backup. My only gripe about this model is that you can't turn off the outlets that are not on the backup. Since it doesn't affect performance, I'm not docking on the rating.

    I bought this because I was tired of power flickers knocking me offline (really annoying when you are online gaming with a friend, and you just disappear for 10-20 mins. due to a 1 second power flicker). This UPS works as advertised. Just one problem, so far: I pushed the power button a bit hard one time and it got stuck. Had to disassemble the whole unit just to get it unstuck. Cheap design.

    Good UPS for a light load

    Living in Florida we are subject to the occasional power blip, either storms ( small & very large ) or the usual construction issues where something breaks a line. I had UPS's in the past, but needed a new one for my router, modem, switch and a monitor. Not a lot of Amps but still critical items. This 450VA unit filled the bill and was at Best Buy with a good price.

    Dissapointed no USB connection to PC

    The only thing stopping me from 5 stars is nowhere on the box does it state there is no usb connection to pc. You only figure it out when you get it home and install. I like the fact that is weighs maybe half the amount of older models, yet still has full 3 year warranty. I would have paid a little more to keep the USB connection so I can utilize the cyberpower personal software.

    I have used CyberPower for several years now and they are dependable and user friendly. I purchased 2 of these this time as we have over 14 units that need standalone power backup. These allow plenty of time and outlet space to allow the backup generator to establish itself efficiently and prevent interruptions to the critical operations they perform.

    I was experiencing frequent power interruptions which required constant rebooting of my WIFI modem and router. My audio tech recommended I try a battery backup unit. So I went to Best Buy and found this unit. This unit woks flawlessly and has resolved my reboot problem. It also was very reasonable in cost.

    I bought this Backup Power Supply for wife because she was using her devices without one. A few days after the purchase my power supply gave out. So, the new supply became mine! How is that for timing? It seems to work well. Have not lost power yet. That is the true test of one of these devices. It has 8 sockets. So far so good.

    a good size for a small-medium powered computer

    Does not have USB monitoring which is fine, it can keep a small-medium sized computer running for a couple minutes on full battery charge. Not sure if it can be silenced when power goes out. That is a minor thing, although I am sure someone will know the power is out when things do not turn on, the beep is just a reminder!

    There was a distant rumble of thunder during a recent storm that caused all devices, ie TV, lights to flicker & reset..Eveything came back except my Dell XPS which required a motherboard. I have added this device as a protective buffer in the incoming power to the XPS. UPS is a bonus and the unit costs much less than that $377 board..

    I purchased this backup for a Ring home alarm base station. The base station has its own battery (supposedly good for 24 hours) but by adding this CyberPower unit I have a tremendous backup system. It is small enough to fit into a small cabinet out of sight. This is a nice small backup unit that works perfectly for low power devices.

    I haven’t had any problems with it. It’s kind of nice going around and traveling and you know you have a backup battery. The only complaint is that when using has a battery it will make an annoying beeping every minute, it’s not annoying enough for me to try to solve it. Maybe I will put a piece of tape over the speaker.

    It did it's job right when our power went out recently. The router and security cameras where connected to independent batteries. Luckily the Internet provider was unaffected as well and we were able to see remotely what was happening although the batteries did not outlast the outage. Overall a good solution for short power outages.

    Shortly after this arrived and I set it up, our power inexplicably went out. I let it run just to see how long I had, and the unit kept my all-in-one computer plus a phone charger and a few peripherals going for 10 minutes or so, which is more than enough to make sure everything's saved and closed down properly.

    I purchased this UPS to power three 3D printers and one laser cutter. I have had one power outage that lasted only a few minutes. Using this UPS saved me the trouble of a reprint. I like this option better than the imperfect "recover after power failure" feature available in the 3D printer firmware (Marlin).
