    No frills simple backup to last long enough for my TV, Cable box, and DVD player and network switch to stay powered, in case of a power outage, for my house generator to kick on.

    I got tired of my cable going off and then having to reboot when the electricity flickered and caused my modem for my cable to turn off. This unit does exactly what it says it does...no more having to wait for a reboot since my computer and cable modem continue to work. Even if the power goes off I still have time to save whatever I was doing on the computer so I don't lose what I was working on

    bought a pair of these for helping maintain power during slight hiccups (we have at least one a month); one is for my PC and the other is for the network equipment; so far they have been successful keeping everything alive during small blips - but I do not have my monitors or other things connected, just the PC and network items

    The battery is user replaceable

    Pros: Provides more than enough power back up for small IT equipment. I use it on my wireless router, cable modem, VoIP modem, and an IoT. The last power outage in my area lasted 15 mins, so I know it will provide power for 15 mins. The big plus is the user replaceable battery. Cons: Only 4 backup outlets. The other 4 are provide surge protection. The outlets are too close for power bricks. I use 6 inch extension.

    My desk setup just includes my gaming pc and a small speaker system, and my wifi modem and router. My power recently went out while I was working on my computer. This bad boy gave me enough time to save my game, quit it out, save some documents I had open, shut my computer down properly, and then gave me time to shut my router and modem off properly. This was a life-saver for that time. I love this thing.

    I wanted a battery backup and surge protector for new PS5, but I didn't need anything too heavy duty. I tested it by charging it up and then plugging my phone into it and then unplugging it from the wall and the phone still had power. This is perfect for a small space.

    I have had this for nearly a year now. I use it to smooth out the power that is fed to my Starlink with my travel trailer. Should there be a power dip, the Starlink continues to function 100% with no interruptions. Works as intended.

    Lost power to my whole second floor. The battery exceeded my expectations. The PC said on long enough for a normal shutdown, while my wifi stayed up allowing me to continue watching my streaming services on the downstairs smart tv.

    Works perfect. Have experienced several power outages, and this kept my computer and monitor running just fine, lots of time to save and shut down. The price was reasonable as well.

    I have had electrical surges at the apartment that I live in that fried my other laptop. Joe, the Apple Representative, was helping me with a MacBook Air. I explained my issues and he recommended this power surge protector. So far, so good. Thank you.

    Battery is easy to replace in the case of failure, has enough juice to run my monitor and my gaming PC for long enough to safely shut down, and has audio and visual indicators for when the battery is in use
