Ok battery backup
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Too big and doesn't provide great service. Smaller sizes seems to work better.

Posted .Hello Cappuccina, It is best practice to compare estimated run times in regards to the amount of power is being used by the unit to the run time charts available on the CyberPower website. If the unit is not performing as expected, please reach out to our support team at 877-297-6937 and we'd be happy to assist.

Low Performance Battery UPS
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Bought this on June 05, 2024 because we had power outages every other month. It worked great for a the time my power went out. However, during our recent hurricane when I needed it most this device only lasted 4 hours. Also I can’t return it because it’s too late. I would recommend a different item.

||Posted . Owned for 4 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I've tried different things to try to get this to work when the power is cut off to my security system, but it just beeps real loud and doesn't seem to run the system without power..

It dont backup crap

Posted .Hello Yvonne, there are several factors such as the age of the unit, the type and amount of load you place on the unit, to just making sure you are connecting to the "Battery Supported and Surge Protected Outlets" and not the "Surge Protected" only outlets (that offer no battery backup) that could explain the failure. If you have not done so already, I encourage you to reach out to us at 1.877.297.6937 or online at https://www.cyberpowersystems.com/support/submit-a-support-ticket/ so we can troubleshoot and resolve this issue for you.

Find something with more power!
||Posted . Owned for 10 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.These last about as long as you can throw them - disappointed would be an understatement. One is connected to an aero garden farm and lasts only maybe a minute or two before it powers down.

Posted .UPS units are designed to provide power enough power to office electronics so that they can be shut down properly. Although not meant for use with an aero garden farm, there are larger units available. If you'd like assistance in choosing a larger unit or feel the unit is defective, please reach out to us at 877-297-6937 and we'd be happy to assist!

Battery did not work
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I bought this backup battery for my work computer and it would die right away once my power went out. It was supposed to give me 355 minutes (approximately 6 hours) but it would die quickly. I exchanged the battery for a new one but it gave me the same problem.

USB ports failed within 1 year of purchase
||Posted . Owned for 11 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The USB charging ports failed within a year of purchase. After some troubleshooting, the manufacturer offered an exchange but only if I pay for shipping back the defective unit, which would be about 1/3-2/3 the purchase price. I can't be without a UPS for however many weeks it takes them to process the exchange, so the "warranty" has no value.

Battery needs powered outlet to turn on.
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I'm not sure if mine is broken but i bought this expecting to have a backup power supply for my phone and a few devices. When hurricane Ian came and I needed the battery it wouldn't start, it seems it will only start when it is plugged into a powered outlet, defeating the whole point of a backup battery.

Posted .Hello Gabe,
This unit has a feature called a cold start lock that requires the unit to be connected to utility power in order for the unit to power on the first time. This is in place to prevent the UPS unit from powering on while being shipped. For more information, please reach out to our Technical Support team at 877-297-6937 Option 1 and we will be happy to answer any questions you may have. We hope to hear from you.

Not What I Thought
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I thought this thing was going to allow me to continue working during the frequent power outages I get at home. Sadly, it just beeps annoyingly every minute or so until it shuts off after only 5 minutes. Sure, it gives me 5 minutes to save my work. But that is the extent of what it does. Maybe I had the wrong impression. I just don't know. But this is nothing more than what the battery on my laptop already does.

Not helpful
||Posted . Owned for 10 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I actually returned this product. It takes a long time to charge and doesn't give you much time of battery backup during a power outage.

Posted .Thank you for your feedback. We're sorry to hear that the CyberPower 750VA Battery Back-Up System didn't meet your expectations. Please note that charging the UPS does take time, and if the system is used with a high load, the backup time will be shorter. The battery will need some time to fully charge to provide optimal performance during an outage. If you are looking for a longer backup time, you may want to consider using fewer devices or exploring a UPS with a higher VA/Wattage capacity rating to meet your needs. We appreciate your input and hope this helps clarify the usage.

Flip a coin
||Posted . Owned for 6 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Bought 2 of these in August, just got their first test in a power failure this morning. Same circuit, with identical computer/monitors plugged in. But only 1 of them worked when the power went out. The other might as well have been a basic surge protector (unless that function isn't reliable either.)
