Kept a steady supply of electricity
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I have this unit supplying power to my modem, router and network storage. It kept a steady supply of power flowing to these devices during the tropical storm, when the power was flickering on and off. Without it my internet would have reset with each power dip. Instead, this device kept me online the whole time.

A Must!
||Posted . Owned for 1.5 years when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.We are always pleased with Cyberpower's products. We need a surge protector for our living room electronics and this allows for multiple units to be plugged in. We live in the capital of lightning storms and this helps prevent most common surges when we are busy at work to unplug devices manually.

Cyber Power
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.This is the 2nd one of these I have owned. The 1st one lasted around 15 years. I mainly have it to give me time to close out my computer in the event of an outage. It does what it is supposed to.

Just what the Dr ordered
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Its our summer of storms in Florida now and this year seems to be a record setting year. I get tired of resetting clocks and other device that dont have battery back up so the physical size, amps and the number of outlets on this ups was perfect. Remember, if you cant put it where you want it, whats the point?

Very good
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I purchased this UPS as a backup for my internet system and worked like it should but it showed its potential when the power went out in Texas. I immediately brought it down from the electrical closet and used it to charge phone and their backup chargers. Also I used it to illuminate the kitchen by plugging in strips of LED lights. It lasted me the 24 hours without power and I’m sure it would have lasted much longer before running out of juice.

It’s ok.
||Posted . Owned for 10 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I bought 3 and one of them died within 5 months. The other 2 are still good. Could have been a bad lemon or lightning, but still kinda concerning.

Great for low load
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Use this UPS as surge protector and battery back up for a computer and screen. Using the Cyberpower software to shut off devices if power fails for longer than available battery back up. It works. No problems encountered. Also have other Cyberpower UPS doing same on surveillance system, router. Good protection.

Good price and good product
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.We bought two of these (his and hers) for desktop pcs'. We have only used one so far because the old one conked out on "hers". We knew our old ones were purchased within days of each other so we would need a "his" replacement soon. The price was nice and so far we are pleased. It has only been on a few weeks so time will tell.

Great backup PS
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I bought this to provide backup power to my cable modem and router. With this we will always have internet available even when the power drops off. Obviously until the cable company is affected by loss of power as well. I recommend an UPS or some sort of surge protection for your large appliances as well.

Great little backup!
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.This is perfect especially if your power turns off for a split second during a storm. This keeps our internet and computers from turning off with that flicker of power during big storms.

Works great
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I purchased two of these to keep my fish tank from going offline during power outage. Fish tank online you say? No, that isn’t a mistake. Welcome to the modern age when even my saltwater fish tank is smart and connected to the internet. Fish need YouTube too. Anyways, not much to say about this device other then it is perfect for what I needed.

Big battery backup...great price
||Posted . Owned for 4 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.This is a great battery backup for when you need one in a hurry to cover your needs. It has all the functionality of a big battery backup in a 650 version. It has every plug option I needed for a monitor, desktop computer, printer, and light. And a great price too.

Proven Protection
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The UPC has already proven its worth during spring storm outages. Usually we only buy the APC brand but a sale on CyberPower presented an excellent opportunity to try one out. Money saving is the demand that 2020 has presented us with, thus we’ll be ordering more of this brand in an effort to save $$!

Great Product and Value
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Definitely works as expected. This particular brand works just as well if not better than the more recognizable name brand. The price point is much better which has encouraged me to buy a couple of more to keep around for emergencies and not have to worry about the power going down.
