If you know a battery that works well and isn’t listed, suggest it in the comments — I’ll keep this updated.
Batteries Compatible with CPAP Machines
🔋 INIU Power Bank
- Type: High-capacity power bank 27,000mah
- Output: USB-C PD (up to 145W)
- Works with CPAP using a USB-C PD → DC converter
- Compact and lightweight
- Best for: minimal setups, up to two night use
🔋 UGreen Power Bank
- Type: Power bank
- Output: USB-C PD (60W–100W depending on model)
- Requires a USB-C PD → DC adapter
- Good balance between size and power
- Best for: optimized overnight CPAP use
🔋 Anker Power Station (C200)
- Type: Portable power station

Required Adapters for ResMed AirSense 10 & 11
AirSense 11 Adapter
- Required to run AirSense 11 from batteries or power banks
- Uses USB-C PD / 24V conversion
- Much more efficient than AC inverters
AirSense 10 Adapter
- Converts battery output to proper DC voltage
- Avoids power loss from AC inversion
- Extends battery runtime significantly
Important Power-Saving Notes (Critical)
- Turn OFF humidifier
- Turn OFF heated hose
- These two features can double or triple power consumption
With both OFF:
- Power banks → usually 1 full night
- Power stations → multiple nights
Summary
- Power banks (INIU / Baseus): portable, limited runtime
- Power stations (Anker): heavier, long runtime
- Always use DC or USB-C adapters, not AC inverters
- Disabling humidity and heated hose is essential for battery use
