These versatile machines run on both gasoline and propane. Propane typically burns cleaner and stores indefinitely, making it ideal for emergency preparedness. Gasoline provides slightly more power output but requires more frequent use to prevent fuel degradation.


Choosing Your Perfect 3500 Watt Generator: The Essential Guide

Calculate Your Actual Power Needs

Don’t guess—calculate. Here’s the foolproof method:

  1. List all appliances you’ll run simultaneously
  2. Find running wattage (check manufacturer labels or manuals)
  3. Identify starting wattage (typically 2-3x running watts for motors)
  4. Add 20% buffer for safety margin

Example Calculation:

  • Refrigerator: 700W running, 2200W starting
  • Window AC: 1200W running, 3500W starting
  • Lights: 200W running

Total running: 2100W
Highest starting: 3500W (AC unit)
Combined peak demand: 2100W + 3500W = 5600W

Verdict: You’d need to start appliances sequentially with a 3500W generator.
