    Computer battery back up

    Had one of these units before. Replaced the previous one since it was like 10 years old. Very important to have a battery back up so your computer and stays on even though the power is cut off. Then you can take the time to shut down your computer properly

    Living in N.C. by the shore I am used to power fluctuations. This little powerhouse has saved me more times than I can count. Easy set up, just remember to charge it the 1st time before usage.

    We purchased this battery backup for the overhead kitchen cabinet lights. I was constantly having to reset the timers when the power flickered off. This far in the country it is a constant issue. The nice thing is that now we have light in the kitchen area even without power!!

    Does what it is supposed to, we have frequent power glitches so needed this for our WiFi modem so we don't have to lose wifi until the generator kicks on.

    Bought this for my home game server and it's pretty good I wanted something that would keep my computer from losing power just long enough for the generator to kick on

    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.

    We are counting on this to prevent power outages for our technology. Living in a rural area, we have many short blips that can be annoying.
