Yes, most UPS units include built-in surge protection to shield your electronics from sudden voltage spikes that could otherwise cause damage.

You can connect computers, monitors, networking equipment, gaming consoles, and other sensitive electronics to a UPS to keep them running during power interruptions and to protect them from electrical issues.
