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.

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.

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.

CyberPower - Small, but Tough!

Cyber power has reasonably priced back-up and surge protection for laptops. I purchased this one as a replacement. My last CyberPower surge protection unit took some good surges and blew one side. The other side still works. It may be small, but it's tough! It protected my laptop and that's what really counts!

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.

Excellent Battery Backup

Anyone who has a computer needs a battery backup system. It protects against power surges which can ruin a computer, plus gives some additional operating time if the power goes out. All our computers are on backup systems. I recommend a battery backup rather than just a surge protector, because if you're in the middle of working on something when the power fails, you won't lose your work, as the battery kicks in, and gives you operating time. CyberPwer makes great back up systems - we've used them for years.

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

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.

I was looking for something to keep my internet going during blackouts. Since purchasing, I haven’t had to use it but decided to give it a try. I unplugged the unit from the wall and timed how long the Comcast Gateway and NetGear router would run. It stayed on for about 2 hours and 15 minutes. In that amount of time I would be able to finish up priority work, inform my higher ups and make a plan on where to go to continue working if needed. This did the what I needed it to do. Only thing better is if there was one that lasted at least 8 hours.

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.
