    Just bought an Apple Desktop 27" with 5k Retina display, so I wanted to protect my investment because there are too many times during stormy weather that the power goes out. This item should be a necessity to protect your computers, routers, etc...

    Not a lot of time if total outage , but keeps the modem from freeking out with the momentary flickers. All attached devices work without interruption like the “ups” means. Like it is supposed to.

    I grabbed these quickly due to a time constraint. I was turning off various breakers to do electrical work in the house and didn't want my Internet service to drop, since WiFi calling is the only way I could receive phone calls, nor did I want constant alerts and issues from other electronics. The two units I purchased worked well for this. However, when there was a 9 hour power outage due to trees hitting power lines the UPS for the modem lasted less than 3 hours and the other unit lasted maybe an hour longer. So these are very undersized if you are expecting to maintain backup power for 4 to 12 hours. Make sure you do the math to ensure you purchase the right size UPS for your needs.

      Hello! Thank you for taking the time to share your experience with the CyberPower 450VA UPS.
      We’d like to clarify that standard UPS systems are not designed or recommended for use with CPAP machines or any other medical devices. While a UPS can support many electronics, using one with medical equipment is considered improper use under the product warranty and is not supported.

      For CPAP backup power, it’s best to use CPAP‑specific power stations or CPAP battery packs, which are designed to safely provide the regulated power these devices require during an outage.

      Thank you again for your feedback! CyberPower

    So far so good. Does not have communication with computer through software although it changed over when I tested with unplugging the battery. Good value if you aren'tSo Far So Good expecting large power consumption. It should have software to shutdown the alarm if power goes out in the middle of the night.

    Was getting frustrated with power disruptions knocking out our WiFi. Big problem when you have a smart home dependent on a strong uninterrupted WiFi signal. Purchased one of these babies and so far, so good.

    An excellent buy for the money! The layout of the outlets on the top eliminates plug overcrowding and keeping all outlets available. The user warnings and other information are clear and helpful.

    I have used CyberPower for several years now and they are dependable and user friendly. I purchased 2 of these this time as we have over 14 units that need standalone power backup. These allow plenty of time and outlet space to allow the backup generator to establish itself efficiently and prevent interruptions to the critical operations they perform.

    I've switched from APC to CyberPower and haven't looked back. I like how this unit has built in USB charging ports at 2.3A and so one less power brick to plug in freeing up the available power outlets.
