Customer Ratings & Reviews

If you have an expensive electronics such as tv or a game console, i would recommend buying this device, not to watch tv when there is no power, but to safely turn everything off.

Really is plug and play: plugged into AC power and plugged a precision balance into output and no glitches when utility power stops delivering AC power. I have more than one CyberPower UPS and all work very well and meet every expectation.

Purchased the back-up system to use for my family room entertainment components to help with random power outages. Easy to use and works great.

Bought it to backup the new FIOS Internet connection in the garage. The WIFI is in the house on a different UPS. I was away from the house during the rolling blackouts and was able to check on cameras and smart thermostat. This product worked very well and met all my needs.

We live right in the main path of tornado alley... Moore, OK. We have erratic weather and get lots of power drops throughout the year. Since I'm working from home, have been purchasing these to put on our expensive electronics to keep things up during those short outages.

This battery backup system works perfect for my needs.

Easy to install. Protects against surges and power outages. This has a small battery but it keeps my computer up long enough to save my documents and shut down.

Has saved my PC from losing files while working! This is a massive help as a Digital Artist. Pleaseeee get this!

Haven't had to use it for anything but a surge protector (no power outages), but it works. Tried plugging in another extension cord because my house doesn't have many outlets and it didn't work so that's unfortunate. Overall at this point I think it's good.

Small, efficient and durable. Living in Florida, there are outages all the time. I've seen it work a few times already and Im happy with this product.

Have had a couple of quick power interruptions and the tv and components that are attached were not affected. So glad we don’t have to reset our UVerse and TV every time there’s a power blip - which is way too often. We got just enough power back-up for a TV, Roku, UVerse, and DVD player.

This is a pretty simple device, but it does its job. Controls are easy to use (to control alerts) and the sockets are well spaced. The only downside is that it smells a bit - an electronic smell. I assume once it "burns in" that will subside.

The battery backup permits the continuous use of the internet modem and wifi during a power outage. This is important while switching back and forth between my solar powerbank and the electric company.

The CyberPower UPS works very well in event of power outages and when used to power low wattage devices when out of range of electrical outlets. It does emit a low chirp when grid power goes out.

I appreciate that the CyberPower - 450VA is much smaller and lighter than previous UPS's that I've had. I only wish the cord were shorter or at least wrapped in the box so that it wouldn't be so kinked when in use.

This power supply has a great form factor and many different sizes to choose from (i own about 4). I have yet to have one that didnt work as advertised.

I wanted something to keep my DSL modem and network switch alive if there's a power hiccup or outright failure. Already have a UPS on my two primary PCs, but wanted the network up in case I'm teleworking. This was quick and easy to set up, and so far is doing its job.

Pros A really good product This is their expertise Great size Durable Solves low power problem Cons NONE Running off one outlet for my PC Gaming rig, speakers had weird static, once I set up my power to run off this cyber power supply. My static issues were gone.

Works good for a power outage. It doesn't beep loudly like my APC battery back up that recently died and wouldn't stop beeping. Like having the extra outlets to protect the tv and console.

We live in a rural area and most of our supplied electrical power is above ground and thus prone to storm outages. We have a back-up power generator but it takes a full 60 seconds for it to start supplying power. If that occurs during sleep hours my CPAP machine will stop and abruptly waken me. If it occurs during TV watching hours, the cable box will require reboot and we miss five or more minutes of whatever program we may be watching. I bought two of these small back-ups, one for the CPAP and one for the cable box. We have had one power loss of about one hour since placing these back-ups in place and they have worked perfectly. No more interruptions!
