Buying Guide

Choosing a Power Station for Your CPAP

How Many Nights Per Charge?

  • • Average CPAP draws 30–60W (45W is a good estimate)
  • • 1,000Wh ÷ 45W = ~22 hours = 2–3 nights of 8-hour sessions
  • • DC mode (12V) is 20–30% more efficient than AC mode
  • • Humidifier adds 15–30W — budget accordingly

DC Mode vs AC Mode for CPAP

  • • DC mode bypasses the inverter for better efficiency
  • • Most CPAP machines accept 12V DC input via adapter
  • • AC mode is simpler but wastes 15–25% energy in conversion
  • • Units with dedicated DC ports are preferred for CPAP users

CPAP Runtime Table

CPAP machines draw 30–60W on average (use 45W as your estimate).

500Wh → 8–16 nights (8-hr sessions, no humidifier)

1,000Wh → 16–33 nights

1,500Wh → 25–50 nights

Use DC mode when available to extend runtime by 20–30%.
