Get one – We had a back up power unit start squealing needing replacement. We walked into Best Buy and left with this unit, drove home, plugged it in to make sure it was charged, then loaded the plugs… Worked perfectly! Nice it was instock and available!

Good UPS for the price – So far so good. Did do a quick check by unplugging the UPS from the outlet and the computer and monitor stayed on via the power from the UPS. Also I would suggest installing the software for the UPS since you can sell some of the UPS status.

Good protection for lower power systems – I purchased this for a small desktop I recently purchased for home use. This tower has a 280W power supply, and is being used with a 28inch, 4K, 60Hz monitor. The system is used mainly for viewing and sorting family photos, shopping, viewing online videos and movies, and other assorted things. This back-up system is well matched to these needs. It is also an economical solution for this system. I recommend it highly.

Basic/solid UPS – Performs well as surge protector. Functional as UPS with small devices such as network equipment, hard drives/NAS and set-top boxes. Recommend a unit with more capacity for components with greater power. Also a curious quirk with the model, one of mine had a problem – iltge audible signal triggered during a surge and wouldn’t stop before fully powering down the unit with reset.

Brought home Power went out min later and worked – it worked. Then after knowing it worked i had zero worry about thunderstorms messing my stuff up.

Ehh!… – This thing works, better than all those kids who “work” at Best Buy” ask a question and they draw their phones out faster than an old western gun slinger. I asked for a UPS unit for my desktop computer to plug into. Might as well asked for a purple rabbit. They could not find one of those either. Found the item myself then stood in line to pay for 20 minutes. Only one checkout register was working, and it was the return desk one! Everybody stop while she asks 20 questions on someone’s return.!!

Functionality of CyberPower Set – This product works great. It does what its suppose to do, give me chance to save my tv when the power goes out in Florida which happens often with the lightning strikes here.

Great little battery back up for the Internet – Title says it all, I bought this because when we lose power, the Internet gets all wonky. Definitely bugs the wife and ends up having her call me. So this little thing has saved us a few times, when power goes out these items keep giving power to the router and the modem so we can get some Internet for a short while until the power comes back up. Very low maintenance and minimal noise. I really appreciate it.
