    Good replacement UPS

    I recently had to replace one of our uninterruptible power supply units when it reached the end of its useful life. The previous UPS had begun beeping intermittently and unpredictably even though supplying power. This new UPS was the most comparable product to my expiring one. I would not operate computer equipment without a UPS.

    Works good, haven’t had a power outage so not sure about the batteries. USB’s charge everything I’ve plugged into them. Affordable does what it’s suppose to do.

    These work great. I’m glad to have them because my power goes out frequently. My only complaint is that no thought went into the layout of the plugins. So many items have power cubes and take up more than one outlet when plugged in as a result.

    I have a number of these battery back up systems. They protect sensitive electronics from power surges and provide battery power to charge phones and keep lights on during power outages.

    Very happy with this purchase. We love the security of knowing our internet power is protected and has backup if the electricity goes out. Definitely would recommend.

    I haven't had to use this in its fullest capacity yet. I charged it up and it seems user friendly and functional. I had experience in using a different brand with similar functions and capabilities last year and liked how it worked. I'm just hoping this one proves to be the same.

    First power outage the UPS worked fine to keep my Wi-Fi, router and fiber box running. Did not lose internet nor was it interrupted. I’d recommend turning the beep off, espically at night as it will wake you up.

    After old backups died needed to replace them. So far they are working fine. Will find out after a power failure which I hope is not in the near future.

    Lots of power outages recently; kept losing my work. Bought two of these—one for the FIOS battery and one for the modem. Power went out, I worked right through it on the internet with no interruption.

    Works great for us. We have power outages all the time and it keeps our internet and wi-fi working long enough that we don’t have to reset everything all the time.
