Customers are saying

Customers frequently mention the 750VA Battery Back-Up System's great size, reliable battery life, and overall performance. Users appreciate its ease of use, excellent value, space-saving design, and adequate surge protection with plenty of outlets. While some find the plug spacing a bit close and the unit somewhat heavy, the noise level is generally acceptable. Overall, the positive aspects of the product appear to outweigh the minor drawbacks.

    Ordered 2 online. Delivered on time by UPS. Nice profile for under desk or Television stand. Went to the wesite and downloaded the app. Connected the ups to the computer. App reconized it and you're done. Only problem is today's plug configuration variations on the devices you need to plug into it.

    A replacement for a same brand product that failed. Not the battery, but something else after 2-3 years. The new one works great after several power interruptions, it never let any equipment go offline.

    I bought this UPS back up supply to keep my cable modem active during a power outage. I recently had a power outage and it kept the cable modem up for two hours. It worked well.

    Grabbed this on sale. Usually I go with more “advanced” APC units, but this model from CyberPower has won me over with its understated reliability protecting a Mac Mini.

    Performance has been solid. This was able to run a monitor, laptop and peripherals for around 20 mins. Bought during the daily deal and got it on sale. haven't used the ethernet ports but I assume they are good as the others. This can also stand on its side which helps with placement.

    Is able to run both my PCs after power outtage and give me plenty of time to shut them down. If you have any type of valuable desktop, it’s worth the investment to protect.

    Does the job, protects your equipment while providing battery backup. Saw this in action when our power went out and was still able to save my files and SHUT DOWN SAFELY.

    Bought this as a battery backup for my wireless internet. I have had 5 power outages since then and it has kept everything up and running! Great product and its unique shape was perfect for fitting in a tight spot where my wifi is located.
