Used for something besides computer equipment!
We do not use this on computer equipment but instead our TV, receiver and DVD player. We live in an older neighborhood. With that being said, we are subject to power “flickers” and short outages. Every time our power would flicker, we would lose the TV signal as well as our internet router would have to “reboot”. Now, I have TWO of these…one on the TV equipment, the other on the internet router and modem. Besides giving us surge protection, now when the power flickers or goes off, we do NOT lose TV nor internet!1

Good battery and surge support in a reasonable size package
Many years ago, a local power surge (the odd thunderbolt) blew out the CPU on an iMac even through a typical power surge protected multi-plug surge protected electrical cord extenders. At that time, I bought the predecessor APC device and went through one cycle of battery replacement. The batteries are lead-acid so they eventually decay. When the second battery died, it turned out that the original device had gone out of support. So…I bought the newer version. The cost was not too much of an increase over a battery alone, especially not when amortized over the lifetime. The new design is sleeker and, I presume that as another reviewer said, the electronics have at least a decade of improvement as well. I don’t need the battery support much, but it is an important part of the surge protection. It has, once or twice, allowed me to shut down cleanly when we had a power outage â rare where I live.The outlets work well. Unfortunately, geometry limits how many power bricks will plug in cleanly. So I make sure that computers and external drives are on the surge/battery outlets and just run an extension plug block from a surge only outlet for any other things that do not require battery like desk lights.This has been a reliable solution to a common problem at a reasonable price. I do not remember why I chose APC in the first place, but I have no regrets. And no more blown CPUs!

Does a good job
I havenât really had an issue with it yet, but I also, havenât lost power for a long time to really test it. It is a good quality UPS, though it is a bit heavy as it uses a lead acid battery for backup, it has decent battery life, averaging around 12 hours powering a low wattage lamp and a phone charger, the silence button is really nice, especially since it is a toggle switch, you wonât wake up to it beeping in the middle of the night.

Working well for my Laptop. Battery died & this will keep my laptop from crashing in a power outage. Tested with battery alone & kept power to my PC. Only did a short test though.

This device has been an absolute lifesaver for my desktop and monitor setup. In areas where electricity cut-offs happen unexpectedly, it has consistently saved my work and prevented data loss. The moment the power drops, everything keeps running smoothly, giving me plenty of time to save files and shut down properly. Itâs become an essential part of my workflow, especially when working on critical documents or during virtual client sessions. If youâre using a desktop or any sensitive electronics, this is one of the smartest investments you can make. Highly reliable and totally worth it.
