For most people, a mid-size Explorer such as the Explorer 1000 v2 is the practical pick for a CPAP. It can cover a night or several nights of typical use. A small unit like the Explorer 300 Plus can handle one night if your machine draws little power. The right size depends on your CPAP's wattage and how many nights you need to cover. Confirm current specs on the official Jackery site.
How to size it
CPAP power draw varies widely. Many machines use roughly 30-60 W, and a heated humidifier or heated hose can push that higher. Check the label or manual for your device.
- Estimate average watts (use the manual's figure, not just the maximum).
- Multiply by hours per night, for example 50 W × 8 h = 400 Wh.
- Allow about 15-20% for inverter losses, so plan on roughly 470-480 Wh per night in that example.
Rough comparison
| Model | Approx. capacity | Rough nights at 50 W, 8 h |
|---|---|---|
| Explorer 300 Plus | ~288 Wh | Under one night |
| Explorer 1000 v2 | ~1,070 Wh | About 2 nights |
| Explorer 3600 Plus | ~3,580 Wh | About 7 nights |
These are our own estimates from published capacity, not tested results. Real runtime depends on humidifier use, pressure settings, temperature and battery age.

- Humidifier: Running it dry or turning off the heater can stretch runtime considerably.
- Recharging: If an outage lasts days, solar input matters. See how to charge a Jackery and the SolarSaga panel guide.
- Placement: Keep the unit ventilated and dry. See using a Jackery indoors.
- Medical use: A power station is a backup power source, not a medical device. Check Jackery's official guidance on medical equipment. If your therapy is health-critical, ask your doctor or equipment supplier about backup plans.
Which one should you pick?
Choose the 300-class if you want a compact, travel-friendly option for a single night. Choose the 1000-class if you want a buffer for multi-night outages or want to power other essentials, such as a phone charger or a light. Go larger only if you are covering other loads too. For a side-by-side look, see the Explorer lineup comparison.
