    I bought this for my 40 gallon reef tank. Between the pumps, skimmer, light, heater, etc., I need something reliable that will keep the critical components running in the even of a power outage. So far, this has been a great solution!

    Protecting a T-mobile 5g internet box. Unit has been working good for months. It has protected during a few brief power sags/brownouts. Cons: - Not cat friendly. The unit is located on top of a table near a window and the cat has hit the power button twice = turning the internet off :( .. lol .. Needs a longer power off delay or harder button.. :)

    we had a power outage for about 30 minutes and worked great but why does it have to beep every 30 seconds to tell you the power is out? The APC battery pack doesn't have that annoying beep unless the batter runs low. It's good if you don't have this battery pack in a bedroom.

    I like the compact size. It's perfect when you only have a couple things to plug in. I bought this for our Fiber Internet box. So far it's protected one power outage. Worked just like it's designed to. I would recommend.

    The CyberPower-450A works perfectly and the price was perfect, it is used to power my workstation and router. It is also a good protection against damages due to power surge.

    Purchased this unit mainly for a small powered recliner. My wife had both hips replaced and if reclined during a power failure she could not lower the leg portion and was stuck sitting until power was restored. The chair load is only 180VA. Once charged, I plugged the chair into the Cyber Power's motor side, disconnected it from the outlet and it smoothly lowered the recliner. Perfect. I'll also add a small lamp.

    Capable protection versus often inconvenient interruptions in power. This model provides enough protection and backup power to orderly shut down a PC (along with all its peripherals) plugged into this unit. Nothing fancy or special, just the basics here.

    This is cheap insurance to keep electronics operational and gives enough time to save and shut down equipment in case of long-term power outage.

    Good UPS

    I bought a UPS since I work from home now and wasn’t sure what to buy. I read plenty my of reviews. We sometimes have power glitches where power would cut off for about a second but then I would lose all of my work and then have to restart and reopen all of my programs. I had to decide what I need, a UPS that can continue running for a long period of time or just enough to safely turn off computer. This one gives me at least 5 minutes and that’s all I needed to safely save my files and turn it off. Works like a charm. If your looking to continue working for a long period of time, you need to buy a bigger unit.

    I bought this battery back up for my dad and it's perfect. It has just the right number of outlets for surge and back up. It's even smaller than the last one.
