I have this backup system connected to my 42 inch LG LCD TV. I've had 6 blips and 1 outage since I purchased this 4 weeks ago. It kept the TV up and running through each of them. I have my DVR attached to the Cyberpower 1500 VA model so that I can still record my shows in an 4-5 outage.

I'm running a built gaming PC in the middle of nowhere, so brief power outages are definitely a real threat to my hardware. If you're not needing more than a few minutes to close any program you need to before shutting down your computer, this is a quality battery backup for you.

Don't go offline just because you lose power

Computers often have batter backups... this is a great solution to keep you online... perfect for a modem and switch/router (whatever network gear you have). When you lose power, don't lose whatever you're working on. Stay online to save your work and shut down properly.

Needed a compact yet high capacity UPS for my home theater gear. This one is perfect. It can handle all my HT gear during those quick brownouts/outages. Obviously not meant for long term use, but protecting equipment from quick outages.

This product is good and especially useful if you can loose electric power during bad weather (like storm). The power outages happened in my area very frequently, so it makes sense to have a back-up battery that would last for several years like this.

This device works wonderfully, with several extra bells & whistles for roughly the same price as the competing product. Installation was a snap, and it has already powered our desktop PC plus monitor during a storm-induced power outage.

Needed a few UPS for systems that need to stay powered on longer than a basic UPS during power outages. Grabbed a few of these off the shelf and they worked great. Would buy again.

This was an awesome buy for the cost. They are very good battery backups, and offer ample plugins for the surge side as well.

This is a pretty decent UPS at a budget friendly price. Works as advertised. Includes software that can save/shutdown your computer in the event of power loss. A good thing to have to protect a far more expensive investment.

Purchased the battery backup for just some small electronics. Has plenty of outlets for normal and large plugs. Perfect for having low power items like a modem and cell phone to run for some time after a power outage.

While waiting for the generator to come on after we lost power. There is a 6 second delay. We have this battery backup to keep several items running until the generator restores all power. They Worked flawlessly.

I've been using APC products for years, but this time I saw this new product from best buy and I didn't have a second thought to buy it because aside from the price value it look similar to APC. I used it for my CCTV and as of now (been having lots of thunderstorms and power interruptions lately) it work as expected and really do exceeded my expectations. A+ product for a cheaper price than APC. Try it for your self you will not regret it.

When my old APC died, I looked around for something compact that I could get up off the floor and remove some clutter under my desk... The CyberPower system replaced the old UPS as well as 2 Power Strips! Love It!

I bought this battery backup for my entertainment because sometimes I lose power for a few seconds which is enough to burn your sensitive electronics.

This is the perfect device if your main concern is ensuring the stuff you are working on doesn't get lost when you loose power. I have a monitor, an i7 pc, modem and router. Works perfecting when power is suddenly lost. The software is simple, but effective. It will shutdown your computer depending on the parameters you set. Met my objective to safely shutdown the computer in case i'm not around. Also i have plenty of time save my work and shutdown if i ever need to.

You can plug in 12 electronics into this machine. Its not much bulkier or larger than any of the other battery back up systems. Would definitely recommend. It works great.
