This is what exactky what I needed: a battery backup that didn't take too much space. Highly recommended for small desk spaces or if you just simply want a minimalistic yet effective way of protecting your equipment.

I have two other Cyberpower Battery Backups and they have not failed me. I got this one for my home office and it's doing its job. I had a power outage during New Years and I was able to stream since everything was on the battery backups.

Reliable and affordable (when on sale) backup UPS power. I have used both CyberPower and APS backup UPS devices over the years and they have both served me well and protected my valuable electronics from power surges, brown outs and blackouts. This unit provides plenty of backup power at a low price. Recommended.

I chose this specific model because it is thin and will easily fit behind our TV Consol in the space between the consul and the wall. The UPS has a good number of battery outlets and two additional for surge protection. Perfect to keep our Wi-Fi router and video camera hub online during power blips. So far, working exactly as desired.

Functional UPS with slim form factor

I’ve purchased several UPS units within my home. Cyberpower seems to be reliable maker. Regarding this particular unit, it offers a different footprint than many of its brethren — I’m using it within a bedroom to back up a WiFi satellite. Due to its narrow depth, it fits nicely behind a dresser for visual concealment. Seems to function as intended.

I had a two outlet battery backup and some surge protector strips that worked fine for personal use. When I went to laptop, dock, multiple monitors, and other devices, I knew what I had wouldn't be safe. There are outlets for items that need battery backup and surge protection for the rest. The device stays cool. Great solution.

Bought it to protect the TV from intermittent power outages and surges. It has proven to work well already in the few short weeks I have had it. It is fairly easy to use. I like the slim line look. It replaces a bulky APC unit where the electronics failed after seven years.

I love this battery back up - It is slim and can fit easily in a server cage - it isnt as small as some server batteries but has as much power and over time is well worth this version as it is easier to remove later that the bolted in version also price is less than half

Great Power Supply. Thin and durable. Low to no noise except when turning on the battery power as the unit is somewhat loud for about 2 seconds.

I love the slim design. It can be mounted on the wall or tucked away nice and neat. I have not have a power outage yet, but have this running a few routers around the house and hope it will last an hour with just that device plugged in. For the price point, you can not beat the design and power level,

Excellent option for supporting home server

Awesome unit for a reasonable price. I have it supporting my unraid server to ensure max uptime. At idle my unraid server runs at 65W and with this ups i can get about 30 minutes of uptime if the power goes out—plenty of time for my server to shut itself down safely. At a higher load i can still squeeze about 15 minutes of power—more than enough for the server to shut itself down. I still think i should have gotten the more expensive version of this device for more time allowed before shutdown but if the power is out for four then 30 minutes i doubt I’ll be trying to watch interstellar in 4k.

I like it. Good value for the price and the size being a good and practical size, Also what I really like is the Power Personal Software where you may monitor your battery backup, including a test option for your unit.
