EcoFlow DELTA 2 vs Jackery Explorer 1000 v2 for a CPAP

This page sizes a power supply. It is not medical advice. Check your CPAP manual and talk to your equipment supplier before relying on battery power overnight.
For a CPAP on its own, it’s close to a tie. The Jackery Explorer 1000 v2 has a slightly bigger battery, so it runs a little longer on every machine in our data, but the gap is small. Where they really differ is in things a CPAP doesn’t care about: the EcoFlow DELTA 2 has more AC output and takes more solar. If the station is only ever going to run your CPAP, neither of those should decide it.
The specs that matter here
| EcoFlow DELTA 2 | Jackery Explorer 1000 v2 | |
|---|---|---|
| Battery capacity | 1,024 Wh | 1,070 Wh |
| Battery chemistry | LiFePO4 | LiFePO4 |
| AC output, continuous | 1,800 W | 1,500 W |
| AC surge | 2,700 W | 3,000 W |
| 12V car port | 10 A | 10 A |
| Max solar input | 500 W | 400 W |
A CPAP draws a small fraction of what either inverter can supply, so the AC output and surge rows don’t matter for it. Battery capacity does, and so does the 12V car port, because that’s how you get the most hours out of either station.
Runtime with a ResMed AirSense 11
The ResMed AirSense 11 runs on AC power for 15.5 to 16.0 hours and on 12V DC for 16.5 to 17.0 hours, depending on the power station and mode.

ResMed publishes one typical figure for the AirSense 11, with no separate number for the humidifier. So treat these as typical-use hours, not a worst case. The ResMed AirSense 10 comes out about the same: 17.5 hours on the DELTA 2 and 18.0 hours on the Jackery, both on 12V. ResMed’s manual for the AirSense 10 also lists a peak draw well above its typical one, which is another reason not to plan right to the last hour.
The 12V DC rows are the ones to use
On both stations the 12V DC path beats AC, because it skips the inverter. To use it you need your CPAP maker’s DC adapter, plugged into the station’s car port. We explain the difference in CPAP on a power station: DC adapter vs AC.
The Breas Z1 is the exception. Breas doesn’t describe a DC adapter for it, so it goes on AC: 43.5 hours on the DELTA 2 and 45.5 hours on the Jackery. It’s a low-draw machine, so it runs a long time even after the inverter takes its share.
If you have a DreamStation 2
Philips doesn’t publish a typical draw for the DreamStation 2. The only figure we have is the power supply rating its manual asks for when you use the humidifier, which is the most it should ever pull. So this table is a floor. Your real runtime should be longer than this, and we can’t tell you by how much.
The Philips DreamStation 2 runs on AC power for 11.0 to 11.5 hours and on 12V DC for 11.5 to 12.0 hours, depending on the power station and mode.
| Power station | Rated capacity (Wh) | Mode | Power path | Runtime (hours) |

And the AirMini
The ResMed AirMini uses so little power that both stations are wildly oversized for it. ResMed’s typical figure is for its waterless HumidX setup, and on that: 146.5 hours on the DELTA 2 and 153.0 hours on the Jackery, on 12V. If the AirMini is your only machine, a smaller station is worth a look. Our CPAP runtime table covers every station we have data for.
Picking between them
For a CPAP alone, the Jackery’s extra capacity gets you a little more time, and that’s about it. If you also want to run other things off the same station, the DELTA 2’s higher AC output gives you more headroom, and its higher solar input means a refill from panels can go faster if you have enough panel to use it. Our solar recharge calculator will show you whether that difference matters for your setup.
We don’t carry weight, size or noise in our data, and for a station that sits next to your bed those can matter. Check both manuals before you choose.
