Excellent value. Slim design wont take much of your table or is more discrete if screwed into a wall. As functionality, battery has lasted this long and the voltage variations are handled nicely by it.

Bought this for my sons gaming system and right after we bought we had a storm that knocked the power off. This battery pack did exactly what is was supposed to by protecting the system from electrical surge and keeping the system running so he doesn’t lose his progress.

Since I now telework, I grew tired of losing my internet connection every time my power goes out for a few seconds. This UPS has been through several outages in the past few weeks and has not missed a beat. My network gear has stayed online and I do not need to worry about losing work time.

This is a relatively thin Battery Back-up that I have mounted on the wall behind my television. It has marvelously prevented the tv from the affects of power surges and gives me time to carefully turn off the tv when the lights go out in storms or brown outs due to construction in the area.

Recently starting buying CyberPower after trouble with their competitor's products. So far so good - no problems. Smaller units have the auto shutdown software which was easy to install on Windows.

A simply designed, hefty little battery backup system. The slim design enables it to be more easily hidden. Already had two power dropouts since having it connected and it did its job as expected.

I got this to protect my new smart TV, laptop, and Blu-ray, both from surge and outages, while the electric company replaces all the poles, transformers, and drops along my street, as well as from lightning storms. It's small size lets it easily sit behind the TV, and plenty of outlets for all my connections. I'm very happy with it

This battery back up is reliable, and easy to setup. I was having issues losing power in one of my outlets and could not get it fixed right away, and this helped to not lose internet (as it's connected to my modem and router). I am willing to bet it will come in handy during a power outage, as well.

These are a must have on all your main electronics. Most people also forget that it’s a good idea to have back up power for your internet router and modem. This one is a great option, it is one of the most compact units and is pretty darn slim. If you can’t afford a home generator for power outages, then these are a recommended option to help get you through for a couple of hours.
If you live in a remote area with limited cell signal, this could be an actual life saving device.

Battery back up for tv, router, sound bar, etc. so appliances do not cycle off when we have frequent electrical blips. Bought this unit about.a month ago and it is working as intended.

This unit replaced our previous CyberPower battery backup system when its UPS outlets abruptly failed. This newer model has a slimmer profile, while also including 2 additional outlets (8 total) and 2 USB ports. Outstanding!
I wish the USB ports didn't require the unit to be powered on, but that is unavoidable since they are grouped in with the UPS outlets. I am unclear whether switching the unit on/off will benefit the longterm health of the battery, anyway.

After several lightning storms caused the power to flicker and lose my work, I invested in this guy. Allows me to keep my desktop running long enough to save work. I love the fact you can decide between battery backup or just surge protection (as in, I don't need all my plugs on battery so as to keep my desktop running longer). I will be getting another one for my router so the internet doesn't restart.

I had my grandson build two computers for his siblings and needed a backup battery to protect from power surges. This unit has delivered thus far. It is large enough to handle three PCs yet still fit on a table where all three systems reside. A very good buy for the money.

I have several of these protecting my electronics. As we seem to have a lot of times that the power goes out for like 20 seconds and comes back on these work great to protect my devices from power events. They work very well for my home network, as it takes like 10 minutes for me to get everything back online if the power goes out.
I fully recommend one of these for anyone that experiences frequent power events.
