    Bought it in August 2020 and now, 6 months later, we have had a couple of small power outages (blip off then on) due to high winds and it has shut down both times! Waste of money. Never buying again.

    Well, I don’t wanna have to use it, but I will

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I haven’t used this yet, but it sounds like an absolutely amazing product to use in a storm. It’s not like I’m excited to use it lol because it’s not a situation you want to be in but if I get in the situation, then I will be very excited to use it because what a brilliant idea to have. Making sure that things don’t just shut off automatically and it gives you time to do that that is a very much appreciated and creative idea.

    Best UPS I've bought

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Bought a CyberPower UPS 7 years ago and its still running and have not had to replace the battery. It is a 1350 AVR for my computer, monitor, u-Verse gateway & DVR & phone base. In a power outage I shut down the computer, monitor & u-verse DVR if running and battery backup power the WiFi, phone & gateway. It has only ran out of battery power once in an electrical outage lasting over 6 hours. I'm giving this one 5 stars in hopes it does as well. Had APC and Belkan UPS's that lasted less than 2 years each. So if this one lasts anything like the 1350AVR I'll be very pleased. Will update this review if the SX950U does not last well past the 3 year warranty. It will be used to surge only protect our TV, amp and video equipment and battery back up the u-Verse TV box as it has to reboot everytime the power fails for even 1 second which is frustrating since lightning storms can cause our power to "glitch" many times in one storm.

    Waiting to use this item. I checked with the size, wattage, price, etc. This model was good to run basically almost 8 hours. The others that were close to this one, were twice the price.

    Great for my desktop

    Not long after my IT guy installed this for me, the electricity in the house flicked in and out before remaining steady again. This time, my desktop kept functioning as though nothing happened instead of shutting down as it did with my previous back UPS.

    Works great. Using it for my PS5 to give me time to shut it down properly or to maintain long enough for the generator to kick on. Its come in handy several times over the last couple months.

    Very nice unit. It was just what I needed for my computer. My last one was 13 years old and the battery still had 10 vlots in it. Great life span.
