About 2.1 days. The EcoFlow Delta Pro stores 3600Wh, and a CPAP with humidifier averages about 60W. At 8 hours of use a day, one charge lasts about 6.4 days.

Medical equipment: these are estimates. Test your own setup and keep a backup plan.

Recharging with solar

The EcoFlow Delta Pro accepts up to 1600W of solar input. In real conditions that harvests about 6 kWh on a sunny day (5 peak-sun hours), or about 750Wh with one 200W panel.

Solar can keep up. A CPAP with humidifier uses about 480Wh a day at 8 hours of use, so with enough panels and good sun the EcoFlow Delta Pro can run it indefinitely.

Tips

  • The heated humidifier roughly doubles a CPAP's power draw. Turning it down or off is the easiest way to get more nights per charge.
  • You’ll still have about 3540W of AC capacity left for other devices at the same time, though they’ll share the same battery.
  • The EcoFlow Delta Pro uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
