    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

    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.

    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 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.

    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.
