### ⭐⭐⭐⭐⭐ Reliable
*by D***E on January 11, 2026*

I use CyberPower UPS's on all of my computers and modems. The batteries last about 5 years and I had to replace one unit in 8 years. They have worked through a number of power failures, and I have used them to recharge cell phones during a power failure. The units give clean power when using a portable generator during a power failure (not a whole house generator).
