Important Medical Considerations
Never Interrupt Your Therapy
CPAP therapy is critical for your health. Always ensure you have backup power available. Test your setup regularly and keep your solar generator charged.
Battery Health Tips
- Keep your generator at 50%+ charge
- Store in a cool, dry place
- Exercise the battery monthly
- Check runtime regularly
DIY CPAP Battery Solution
For longer trips, you can build a simple battery pack:
What You Need
- 12V lithium battery (100Ah+)
- 12V to 24V DC converter
- CPAP DC power cable
- Fuse and wiring
- Battery box/container
Note: Always use a DC-DC converter (not a simple voltage divider) to ensure your CPAP gets clean, stable power. A 100Ah battery can power a CPAP for 5-7 nights without a humidifier.
