A UPS isn't just for storms anymore. In areas with brownouts, bad wiring, or even dirty power from cheap multi-outlet strips, a UPS protects your desktop, monitor, and router from sudden shutdowns and data loss.
After testing six units with a desktop + 27-inch monitor + router load, these are the ones that actually delivered on runtime.

What Runtime Do You Actually Need?
Use this formula:
``` Target runtime = time to save work + shutdown safely ```
Most people need 5–10 minutes: - 2–3 minutes to save and close apps - 2–3 minutes for OS shutdown - 2–5 minutes buffer
If you want to keep working through short outages, target 15+ minutes at half load.
