    I bought a small unit to keep my Modem/Router powered since I rely on constant Wi-Fi for my Ring cameras, this does the job nicely. It does get mildly warm but nothing dangerous. Obviously not meant to power a full desktop PC. I do wish it had the ability to connect to a computer to monitor status, the higher-end models do this, it would help keep track of the operational lifespan of the unit.

    Clicks are super annoying with no way to disable them when they start occurring. Like yes i know, the power is out, but you know what, I'm keeping the modem and router on so shut up. Good product, if this is the power you need, get this product, but I'd recommend just going with a bigger capacity UPS

      Hello Jacky, When you say clicks, are you talking about the beeping every 30 seconds when the unit is on battery power? On the SE450G1, those can be disabled by pressing the power button 2 times, quickly. If you have any questions, please reach out to our support team at 877-297-6937 and we'd be happy to assist. Thank you for submitting your review! CyberPower

    Great little UPS, it's not going to run everything, but it will hold your PC and other small electronics through momentary power brownouts and allow you to shut down safely if it's going to be an extended outage.

    Works great. What is wasteful and dumb is when the battery life ends. Cheaper to buy a new unit than a replacement battery Do BETTER Best Buy. Recycle these batteries and sell for $5 less than a new unit. This = less plastic used

    Works great, and there are mounting holes in the back for mounting it to a desk. It is a great back up and piece of mind to not worry about losing work from power outage.

    The receptacles are set up well for my needs, as i have several devises that use “Wall warts” for power, and the prongs are set in. a way where they block other receptacles on UPSs where they are 90 degrees turned from how they are on this unit.

    Before buying this product, my laptop had a power surge and broke down. I have been using this product for over 2 months and it is working fine as expected. I would recommend this product to be on safe side from power surges.

    So far so good. I have only had it a short time, but the one power outage I had so far, my computer stayed on so that I could shut it down properly which is why I bought it.

    Excellent battery back up. Was tested a couple days after purchase by a freak thunderstorm that knocked out power. Stayed on and allowed more than enough time to save important files and safely shut down devices.

    Basic of basic UPS. Does what it says it does and nothing more. No, it won't backup 1500 watts. Yes, it will backup modern PC, with limited loads. That's it.
