How to choose the right UPS

Understand these six key factors before choosing a UPS for best value and continuity.

1
Sum device power (W)
e.g., PC + monitor + router totals 320W
2
Calculate UPS size (VA)
Formula: VA ≈ (W ÷ 0.6) × 1.3 → 320W ≈ 690VA+
3
Match UPS topology to the job
Offline = basic • Line-Interactive = office/POS • Online = best stability for servers
 
4
Decide runtime (backup time)
Choose 5–10 minutes to save work, or 15–30 minutes+ to keep working.
5
Check ports and installation
Ports USB/RS-232/SNMP, choose Tower or Rack.
6
Plan for future growth
Choose capacity about 20–30% above your calculation.

FAQ – Frequently Asked Questions

Which UPS suits you best?

What devices can a UPS support? Click to view answer
Works with common IT/electronic devices: PCs/laptops, POS, NAS, routers/switches, NVR/DVR CCTV (via PoE), servers/workstations, telecom gear, and network devices.
Avoid: Motor/compressor loads (water pumps, fridges, AC) or high-power heaters.
Sizing tip: Sum device wattage and add at least 20–40%, and avoid running the UPS above ~80% of capacity.
Which type should I choose if outages are frequent? Click to view answer
  • Home/office: Line-Interactive + AVR, VA rating 1.5–2× total load. Choose Long Backup models or external batteries for longer runtime.
  • Critical/server workloads: Online (Double Conversion) for the most stable power, external battery options, SNMP/remote alerts.
Need a specific runtime? Send your device list — we’ll calculate VA/Watt and runtime for free.
How long do UPS batteries last? Click to view answer
Typically, Sealed Lead-Acid (SLA) batteries last around 2–3 years (at 20–25°C, normal use). Higher temperatures/frequent outages shorten life. Some brands offer Lithium packs with a rated life of 5–8 years.
Care tips: Ensure ventilation, avoid deep discharges frequently, and test batteries every 6–12 months.
Can I replace the batteries? Click to view answer
Yes — many models support battery replacement (some are hot-swappable). Use genuine/same-spec batteries, power down and unplug before replacement, or have a technician perform it. After replacement, run self-tests/calibration via software and recycle old batteries properly.
