Typical wattage range
20-40 W. Use a measured average when the device matters.
Medical comfort
Travel CPAP Runtime Estimate
Travel CPAP units can draw less than full-size machines, especially without heated humidification.
Planning default
30 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 30 W if you do not have a watt-meter reading yet.
- Travel CPAP 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.
- For CPAP or other medical-comfort planning, use the device manufacturer's battery guidance for critical backup decisions.
