This is good for basic low wattage PC's.
I have this on an older PC. I wanted it for battery backup and surge protection. Buying a surge protector is in the same price range. So, why buy just a surge protector, when you can buy this and have battery backup also. Yea, a surge protector can last longer than when the battery needs replacement on this, but it should be good for 3-4 years before the battery needs replacement.

TOP CRITICAL REVIEW
Working As Designed...who checked??

Light, compact for low loads.

Unit ran ~ 1 year supplying power to a router and 2 modems (~36W), which in my situation is critical because I have VIoP and Web through it. We did have a power outage and my 550VA went dead when I needed! It was the battery but no alarms nor notifications occurred prior to AC outage. So, before buying another one I decided to investigate the units functionality. After few measurements I am convinced that CP's design and validation is very substandard (perhaps on this unit), AND I will not be buying another unit from CyberPower. Here its why:
1. with a known-good battery (12V/5.5Ah) the battery backed AC side of the unit produces 102.7V instead of ~110-115vAC VAC and shorty drops to 97VAC; very unstable.
2. with fully charged battery ~14.2V, main AC removed, and ~36W AC loaded, the unit reports, through the USB software, ~5-7 min of run-time...really????
3. Looking at CyberPower Personal Edition Status with battery disconnected and AC ON,the "Remaining battery Capacity " AND "Battery Status" shows 100% How could that be!!!?? However, this explains why there were no prior alerts from the unit. Removing AC power with bad battery has a predictable effect on the load. I would have attached photos of the set up and readouts but space/tool doesn't allow that .

none.
