    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.

    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.

    Excellent slimline design, plenty of receptacles, easy-to-read print on top near plugs, doesn't get "super-hot" to the touch either. This is a quality product, I've bought from Cyberpower before!

    I bought this battery backup to protect my computer system, and it works great. The setup was seamless and easy. I have not had any issues. I went back and bought two more.

    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 liked that the unit takes up a lot less shelf space than the unit I replaced. You can also use it laying on its side and it's still smaller than my original unit. I am using it for my cable box, TV and audio system backup.

    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.

    It's been 1 year since I've had this UPS and it is still going strong. It's dealt with a more than a handful of power outages and blips and is still solid. For reference as to what I have attached to it on the battery is my UDM Pro SE and an Aruba 2930M 48port poe+

    So far so good. Power went out today with both me and wife working from home. First time with this in place. Kept the router and modem running. Did not last too long with multiple devices plugged in. But we did not get kicked out of calls and that was the plan for this. Be sure to read how to turn off the audible alarm. Once it’s running on battery power that can get annoying quick.

    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

    Heavy weight, slim design, easy for placing in almost any setup. Keep in mind you should charge it for 8 hours prior to using. But overall, easy to uses and does the job!

    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.

    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.
