Buying Guide: Key Purchase Considerations
Capacity and runtime: Assess your total monitored load and desired runtime during outages. Detector-based runtimes vary; for a PC with peripherals, a 600–1000 VA unit may cover short outages, while higher loads benefit from 1500 VA or more.
Surge protection and outlets: Count battery-backed vs. surge-only outlets, and verify if Ethernet or network protection is included. If you rely on a router, modem, or NAS, ensure there are dedicated data protection features.
Power quality: True sine wave or pure sine wave output is important for systems with active PFC power supplies or gaming-grade PCs. This improves efficiency and protects sensitive equipment from harmonic distortion.
Battery technology: Lead-acid options are common and affordable, while lithium-based UPS units offer longer lifespans and reduced maintenance. Consider total cost of ownership when choosing LiFePO4 vs. traditional chemistry.
Management features: LCD or LED status indicators, software for automatic shutdowns, and removable batteries or serviceability can impact maintenance and ease of use. Windows, Mac, and networking compatibility matters for centralized monitoring.
Physical footprint and placement: Wall-mountable options or compact desktop designs help with space-constrained setups. Right-angle outlets and transformer spacing improve accessibility for bulky adapters.
Replacement and serviceability: Some models have user-replaceable batteries, while others require technician service. Consider your comfort level and local support options.
