CPAP Battery Runtime Calculator

Use this calculator to estimate how long your EASYLONGER battery can power your CPAP device.

What Affects Runtime?

• Power Consumption: Using heated humidifier or heated tubing increases the power draw significantly.
• Battery Capacity: Measured in Watt-hours (Wh), higher capacity means longer runtime.
• CPAP Settings: Higher pressure settings typically require more power.

Typical Scenarios (Based on ES960 Battery):

• Humidifier + Heater ON (CPAP Power: 35–40W): Approx. 6–7 hours
• Humidifier Only (CPAP Power: 20–25W): Approx. 10–12 hours
• All Features OFF (CPAP Power: 7–10W): Approx. 24–34 hours

Note: Runtime estimates are based on a fully charged ES960 (297.6Wh) at 80% efficiency. Actual results may vary depending on your CPAP model and settings. This calculation is for reference only.
