Why Most Power Stations Aren’t Ideal for CPAP

Many camping power stations:

• Use standard lithium-ion (shorter lifespan)

• Require AC inverter (wastes 10–20% energy)

• Are heavier per usable watt-hour

• Lack direct 24V CPAP output

Dedicated CPAP batteries:

• Provide direct DC output (more efficient)

• Deliver longer cycle life (LiFePO4)

• Are optimized specifically for CPAP machines

CPAP Machine Compatibility

EXP PRO batteries are compatible with:

• ResMed AirSense 11 (Check out our guide here)

• ResMed AirSense 10 / AirCurve 10

• ResMed AirMini

• DreamStation & DreamStation 2

• Luna G3

• Transcend Micro

• Breas Z1 / Z2

• And virtually all CPAP machines with correct cord

Direct 12V and 24V outputs eliminate inverter loss.

How Many Nights Do You Actually Need?

Quick rule of thumb:

• 1–3 nights → 150Wh range

• 4–6 nights → 300Wh range

• 7+ nights → 700Wh+

Turn off humidifier and heated tubing for maximum efficiency.

Frequently Asked Questions

Can I use a CPAP battery while charging?

Yes. Pass-through technology allows use while charging.

Can I fly with a CPAP battery?

Only batteries under 160Wh are airline compliant. The EXP48PRO (154Wh) qualifies.

Can I run my CPAP with humidifier?

Yes, but runtime decreases significantly. Only larger batteries like the EXP240PRO support multiple nights with humidification.

Is LiFePO4 safer?

Yes. LiFePO4 batteries are more stable, safer in extreme temperatures, and last significantly longer than standard lithium-ion.
