Introduction
For anyone using a CPAP machine, uninterrupted power isn’t optional — it’s essential for safe and restful sleep. Whether you’re camping, RVing, or riding out a power outage, a portable power station provides a reliable, quiet, and indoor-safe solution. In this guide, we’ll cover three of the most dependable options — from Jackery, EcoFlow, and BLUETTI — all capable of powering a CPAP machine for 8–12 hours overnight.
Why Choose a Portable Power Station for CPAP Use?

- Rechargeable – Wall, car, or solar charging for flexibility on the go.
- Reliable backup – Seamless therapy during blackouts or off-grid trips.
- Travel-friendly – Compact enough for bedside or RV use.
Key Features to Look For
- Battery Capacity (Wh) – Needs enough watt-hours to cover a full night (8–12 hours).
- Pure Sine Wave Inverter – Protects sensitive CPAP electronics.
- Output Options – AC outlets plus DC ports for direct CPAP adapters.
- Recharge Flexibility – Fast wall charging and solar compatibility.
- Battery Chemistry – LiFePO₄ cells last longer and are safer.
- Portability – Lightweight enough to move easily.
- UPS/Auto-Switch – Seamless transition when power goes out.

- Turn off humidifier/heated tubing during backup power use.
- Fully charge before bed to guarantee overnight runtime.
- Add solar panels for recharging on multi-night camping trips.

Premium benefits: Longer cycle life (LiFePO₄), fast recharge, multiple port options.
Worth it: For CPAP users, the reliability and peace of mind far outweigh the cost.
Safety Considerations
- Only use power stations rated for indoor use.
- Confirm your CPAP’s wattage draw before choosing capacity.
- Remember: portable power stations are backup solutions, not FDA-approved medical devices.
