I have multiple UPS units from CyberPower. All perform well. I got this affordable unit as a battery backup for a power reclining loveseat.

This affordable unit is all I need for my desktop computer and printer. If I were a gamer I probably would want something with more power and additional features, but this is perfect for my specific situation.

Needed something to buy me a minute or 2 when my son punks me by turning off the power switch . This does the job and nothing compared to my 1500va device .

I have not tested it in an extended power failure yet. I bought it to handle small blips in power and it is doing great great for that purpose.
Size is not bad. Outlets are well spaced to handle any plug I have. I was concerned because in the picture I thought that middle section was raised and that could cause some problems plugging in larger plugs. In reality, that middle section is a depression so it works well.

CyberPower Back-Up System

I actually wanted a smaller unit with just 2 or 4 outlets. However, the alternatives were either incredibly complicated or too expensive. Of the reasonably priced and simple back-up systems, this is the better choice than the nearest competitor, APC. This unit fits flat and is smaller with essentially the same features. Price is better also.

Solid, Basic Battery Backup

Just wanted backup for the cable router/wifi... so when the power flickers I don't have to wait 5 minutes for XFinity to start back up. This fits the bill and is small enough/light enough to allow for different placement options while taking advantage of all the outlets.
If you are looking for surge suppression over for the cable/coaxial itself, you'll need to step up to the next model.
You'll need to charge it before using it... which is probably better for the environment and the battery life than having it charged before it left the factory.

Smaller and lighter than the one I replaced. It seems sturdy enough, and performs well for the first month I've used it. Highly recommended... I would buy this again for sure!

This backup battery/surge protector is perfect for my needs. My laptop has some backup protection. This device provides additional backup protection. This device also provides protection for surges in electricity which can occur during a rain storm. The CyberPower - 450VA was the perfect choice for my needs.

Honestly this was the best $50 I've spent in years. I currently work remotely in costa rica and the power goes out ALL the time. This little baby keeps my modem and therefore the internet up and running non-stop. Its a life saver.

Using it on an electric recliner chair, after a neighborhood power outage made it difficult to get out of the chair while it was fully reclined. The battery backup allows the chair to be closed so I can get out.

I needed to either buy a replacement battery for an existing UPS or, lo and behold, I found this. It was a little more money than a replacement battery, but knowing technology changes, I decided to replace the UPS instead. I'm glad I did. Somehow, this is the smallest UPS I have owned and at no loss to the number of outlets or VA. Definitely a good purchase.

does what it's supposed to do. So far so good. I used to use their major competitor's UPSs but they started having problems so I saw good reviews on CyberPower and they're good.... so far, and with a better price.
