Understanding Power Requirements

Continuous Wattage: The total watts your power station must provide continuously to run all devices at once.

Recommended Output: Continuous wattage × 1.2 safety margin to prevent overload.

Surge Wattage: Motors and compressors need 2-3x their rated wattage for startup (typically 2-5 seconds). Your power station must handle this spike.

  • Refrigerator: 150W running, 450W surge
  • Power tools: 500W running, 1500W surge
  • Air conditioner: 1200W running, 3600W surge
