    I have purchased Cyberpower a number of times for both my wife and myself over the years. We use it for everyday computing to allow us to power down our computers and to finish and save our task at hand. You have 4 outlets for battery backup and 4 for surge protection only. As far as I am concerned it is an essential part needed for your computers. You will be glad that you had one the first time your power just shuts down and you lose all the information you were working with before you saved it.

    This is the second backup system I bought. Worked like a charm. No problems. Power went out several times. I did what I was supposed to do.

    I last bought a battery back up about 5-7 years ago. I didn't realize how much they had improved with regard to size, price and length of battery power.

    This is a solid battery backup that will protect you from power fluctuations and keep you going long enough to prepare if the power is not coming back anytime soon.

    Solid Battery Backup Surge Protection

    Great product at a great price! I have been needing a battery backup surge protector for some time and this one was just the right size. We have our cable modem and router plugged into it. That way if power goes out we at least still have the internet, since our internet is through the cable company. The only thing to note is that only one side is battery backup, but both sides offer surge protection.

    We buy these constantly as our office location is remote and we have a lot of power "anomalies". I've had the best longevity with Cyberpower products and typically prefer them over other brands. On average we get about 2.5 years of life from them and when they finally do fail I send the batteries off to a recycler. Overall they are good reliable products and will protect your computer from most power anomalies.

    Hard to review as I just set this up to protect my modem and router. No power outage as of yet. Will see when that happens. Easy to set up (plug in) and inexpensive.

    Keeps your data safe from power outages

    I bought this for my ps5 as I live in a place with common thunderstorms and power outages and it gives me time to save my game and turn it off when the power goes out so my data doesn't get corrupted. If you want to play when the power goes out, this isn't the one, but if you need it to protect your electronics, then it's perfect. Comes with a cable you can plug into a PC and if you download their official software you can see how much time your battery will last if the power goes out. Great product, highly recommend

    Purchased for small home office and works extremely well. Set up is extremely easy and immediately starts to work as soon as the battery is fully charged. I’ve had a few of these over the years specifically this brand and they’ve generally lasted way longer than I thought they would considering Florida has so many lightning strikes. Excellent product!

    I use this battery backup on my cameras and dvr for home security, it keeps the cameras and dvr online along with my wireless router and modem so even if the power goes out I can monitor my 8 cameras from my mobile device and also know a recording is still taking place. The unit is located in a non air conditioned garage in Florida where temps get into the feels like of 120 degrees and the product works amazing.

    Easy to use with clear markings on which outlets are battery protected and which are surge protected. Profile is good when mounted to a vertical surface like a desk or wall to make cable management easier. The runtime is also a factor in choosing this unit for a simple computer/monitor combination.

    This batter fits the needs perfectly for a desktop computer station. Four outlets are battery supported, four are not, but all eight are surge protected. It works very well.

    The area that I live in is prone to short power outages anywhere from a few seconds to 3-4 hours every month or so. I have bigger CyberPower units on my tv and computers. I put this one in an inaccessible area to keep my incoming fiberoptic connection active. The UPS works great and we still get at least a couple of hours of internet access during power failures. I could probably extend it longer but attached USB fans to UPS to keep the fiberoptic equipment cool. I was hoping that the USB power ports would be inactive during power outages but they are still active and the fans drain the battery.
