Typical wattage range
750-1500 W. Use a measured average when the device matters.
High draw
Small space heater Runtime Estimate
Resistive heaters drain batteries quickly. They are usually a poor fit for compact portable power stations.
Planning default
750 W at 100% duty cycle.
Confidence label
estimated. Treat the result as a planning estimate, not a lab measurement.
How to use this scenario
- Start with 750 W if you do not have a watt-meter reading yet.
- Small space heater is treated as a continuous load, so runtime is sensitive to the real wattage you enter.
- Keep at least a planning reserve because battery age, temperature, output path, and device settings can move the result.
Watch-outs
- The scenario wattage is an estimate. Measure the real load before relying on it for outage, travel, or critical planning.
- High-wattage loads can hit inverter limits quickly; check continuous AC output and startup surge before trusting a station.
