Buying Guide: Key Purchase Considerations

  • Power capacity and runtime: Match VA/W ratings to your equipment and desired runtime during outages. Larger setups benefit from higher VA and multiple battery-backed outlets.
  • Outlet configuration: Consider the mix of battery-backed vs. surge-only outlets. Ensure critical devices have dedicated battery backup outlets.
  • Power quality: True sine wave vs simulated sine wave output impacts sensitive electronics. PCs, monitors, and network gear generally perform best with true sine wave units.
  • Management features: LCD displays, software integration (PowerChute, Eco software), and data protection features help with monitoring and orderly shutdowns during power events.
  • Battery chemistry and lifespan: Lead-acid units are common and reliable; lithium-based options (like LiFePO4) offer longer lifespans but may come at a higher upfront cost.
  • Protection scope: Look for AVR (voltage regulation), data line protection (Ethernet/Wi-Fi ports), and USB charging ports for convenience.
  • Physical footprint and noise: Consider size, form factor (mini-tower vs. wall-mount), and operating noise if placed near workspaces.
  • Warranty and serviceability: Check warranty length and whether batteries are user-replaceable or serviceable by technicians.

When selecting a UPS, assess your typical outage duration, whether you need to gracefully shut down a computer or protect a small server, and how much space you can dedicate to a unit. For broader home or office networks, a higher-capacity model with multiple battery-backed outlets and robust protections provides greater resilience against outages and voltage irregularities.
