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.

    Nothing to write home about. I bought 2 of these. Initially I was going to use these for 2 seperate tv/entertainment setups in my home. I've only opened 1 of 2 so far. Hooked it up with a larger UPS for my networking setup. When I turn a space heater on in another room, this starts to beep. Might just be something with my home electrical setup though. If I was to purchase again, I'd purchase something larger.

    This little UPS is great! I’ve been using it for my tv and PS5 incase there is a power outage. I keep my PS5 in rest mode, so this would allow me to turn it off correctly and not hurt the system.

    This is a must have for anyone with a whole house automatic generator - that tests itself weekly. The unit protects vital computer equipment against the drop/surge of the generator cycle.

    My battery backup system was giving problems even after replacing the battery. I found this one and really like it. It is more streamlined with a better system. Gives peace of mind for the safety of my computer.

    I use APC at work, but for basic protection at home it's a goog product. My last CyberPower battery lasted 5 years.

    I think this is a decent unit for what it is. I wish it had a display just to know when the battery was going bad or some type of self test. I have it connected to a NAS so I can't use CyberPower software on it. In my past experience they tend to go bad after about two years and battery replacements almost cost as much as a new one, so I slapped a date sticker on it an will replace it then.

    Making it Work for Me

    It works fine. The shape is the problem, it is taller and much thinner than the former UPS. There are not as many outlets, the problem I'm having is getting things (iPhone, iPad) plugged in and unplugged. I'm 80 and my hands aren't strong. Have finally just left the plugs in and remove the cords when not in use.

    Simple hook up, and easy to monitor with you laptop or PC if you chose to do so. The "slim" design worked well for my application as far as placement goes. I had 1 small brown out since I hooked up this UPC, and it did it's job, nothing dropped off.
