    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.

    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.

    After one electric utility outage, the unit worked great. With a standby generator there is about 10:seconds without power between when the utility electric system goes down and the standby generator is working. ATT modem and wifi routers never saw the power outage because of the UPS.

    Overall this is a great device. I have it plugged into my Mac Mini M1, A LG Ultrawide display, and my desk lamp. My power would hit random surges and this has been a lifesaver for my devices. It's worth it at the price and is perfect for a small office setup.

    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).

    Living out in the country we are always having power outages. Do many power outages I have an automatic generator that kicks in after 10 seconds of power loss. This device is to bridge that time to keep my internet modem abs router online.

    fits it purpose well. I have an iMac desktop I have been using to WFH for the last year. Forgot the challenges with power outages shutting down desktops. only complaint I have is lack of USB port to connect into my Mac to start the shutdown sequence when the power fails. I overlooked that when purchasing but still kept the unit. I have it attached to my standing desk.

    I bought this so if the power went out, I could properly shut down my PC. I have my monitor and desktop hooked up to it and so far, the power has gone out several times and it performed as expected.

    Does the job. More compact than the same capacity unit it replaced. The plug orientation is 90 degrees from the previous but was able to connect the same equipment, even the ones with transformers. If you have polarized plugs you will be limited

    I bought for my ps4 for when my power goes out. I didn't want the ps4 yelling at me anymore and didn't want to risk damage of hard drive. I just have ps4 and my Tv plugged into the battery side which is about all that side can handle wattage wise. What I don't like is the loud beep it makes when it powers on and off.

    This battery backup unit is being used with my Netgear Cable Modem/Router so that it is still up during power outages. It is working great so far.

    Has served us well for brief power outages so we don’t lose WiFi on virtual meetings. The massive box that it shipped in was pretty ridiculous. I thought best buy messed up and sent me a large console tube television set. Other than that, it’s been working great and has been activated during power outages several times. Note - it needs to charge for 8 hrs before using it.
