    Worse than a paperweight

    Absolute trash. Could be a nice paperweight but cord makes it difficult to have a desk. Didn't work out of the box and Best Buy refuses to take it back and CyberPower's warranty service is a joke.

    Thrown out money. It won't keep up a small form factor PC and a single monitor. Every morning it's screaming in pain. Sad part is the computer was off. Hold the button and restart it and it works till the next day. 450VA should have been more than enough especially with the current on. Couldn't return it because of the pandemic so it's good for keeping a clock radio running . Like I said get a bigger one or get an APC.

    I bought 2 of these units. One was defective and never came on. The other runs for 2 hours then turns off. Very disappointing as I had bought them when I travelled abroad in an area where we experienced constant blackouts and needed these to protect my electronics.

    Biggest piece of poo that I've ever purchased. I needed a surge protector and battery back-up for an overseas trip. Straight out of the box the battery was dead, and the surge protector side died two days later. Buy at your own risk!

    Died in less than two years. Called the warranty number and left a message. Never got a callback. Warranty will expire in days now. Not worth my time for a $50 piece of junk to hunt them down.

    We had a power outage last week and the connected TV and entertainment center connected lost power. Two hour backup battery???

      Hello Edward, run times will vary based on the power drawn from the unit. An entertainment center is going to draw a lot more power than a router or modem. If the unit was unable to provide backup power altogether, please reach out to our support team at 877.297.6937 and we'd be happy to assist! CyberPower

    Unfortunately after a year of using this backup, it has never worked in our frequent power outages. It shuts off several times a month with no warning, crashing my server. I just have 1 server, 1 computer, and 1 monitor attached. I haven't found any solutions online to keep it from shutting down. I'm now looking for another brand.

      We would be happy to walk through the process with you to offer a solution or recommend a product that better suits your needs. We can honor the new product warranty manufactures defects 3 years form the date of purchase. There are only several reason why we replace the product under warranty, and these practices are industry standards. They usually include big and powerful products being plugged into a small battery, and high voltage devices that the UPS is not designed to handle. We would be happy to replace the product if it is being used under normal conditions and look forward to speaking with so we can help. Please call us at 1.877.297.6937. CyberPower

      Thank you for your review! It’s completely normal for the battery in a new UPS to slowly discharge between the time it was manufactured and when it's purchased and put into use. Because of this, it's standard practice to charge the unit for up to 8 hours when you first receive it. Additionally, if the battery is completely depleted while running on backup power, it can take another 8 hours to fully recharge. This is typical for UPS units, regardless of the brand. CyberPower
