I have owned and used a few different UPS units by CyberPower over the years and have been quite satisfied with their performance. I bought this UPS power supply for my spare computer system. I only needed to power a monitor, computer and external hard drive. It seems to be functioning quite well for the intended purpose. I have a much larger CyberPower UPS unit for my main system. The CyberPower brand of UPS units are reliable and price competitive.

Unit arrived as scheduled. Unit has functioned perfectly for the small time i have had it (2 weeks). After full charging it overnight, I unplugged it from the 120v power and my television stayed on without any problems.I only it left it unplugged for about 5 minutes, but all looked well.

Got it to back up my Comcast modem. The only Energy Star modem in its size and price that I saw. Some other UPS's make noticeable humming noise. This one is quiet.

We lose the power where I live during all 4 seasons, so I invested in this battery backup. 2 months after installing, the power went out for 3 hours. Grateful I had this and when the power came back on, so did my electronics (without losing anything).

It's heavy, it's large, but it functions OK.
