Jackery
Simple operation and a well-known name, which matters for a medical purchase.
Buying scenario
Best portable power stations for CPAP and medical device backup
A CPAP is a nightly, non-negotiable load. Sizing is straightforward once you know whether the humidifier and heated tube are in use — and it changes the capacity you need by more than double.
The short version
Who: CPAP and BiPAP users who need guaranteed overnight power
The spec that decides it: Capacity (Wh) — The whole decision. Humidifier and heated tube can double or triple draw.
What they get wrong: Sizing for the CPAP without the humidifier, then using the humidifier
Who is buying
- CPAP and BiPAP users who need guaranteed overnight power
- Households with a home oxygen concentrator or similar device
- Anyone whose outage plan cannot tolerate a single missed night
Why they are buying
- A missed night is a health issue, not an inconvenience
- Battery packs sold for CPAPs often cover only one night with no margin
- A station also covers the router, lights and phones in the same outage
What it will actually run
- CPAP or BiPAP running six to eight hours nightly
- A second night without recharging, for longer outages
- Other essentials alongside it in the same outage
The specs that decide this purchase
In priority order. These are not the specs with the biggest numbers — they are the ones that change whether the product works for this buyer.
| Spec | Why it decides the purchase |
|---|---|
| Capacity (Wh) | The whole decision. Humidifier and heated tube can double or triple draw. |
| Continuous AC output | Modest for a CPAP, but confirm the device tolerates the inverter waveform. |
| DC output option | Running a CPAP from 12V DC instead of AC can extend runtime substantially. |
| Recharge speed | You need it full again before the next night. |
| Pass-through charging | Keeps the unit topped up while it stays connected. |
What this buyer pays extra for
- Enough margin for two nights, not one
- DC adapters for their specific device
- Silent operation in a bedroom
- Predictable, simple operation under stress

How much capacity you need
| Band | Capacity | What that buys you |
|---|---|---|
| One night, no humidifier | 300–500 Wh | Typical CPAP draw only |
| One night, with humidifier | 600–1000 Wh | Roughly doubles the load |
| Two nights plus essentials | 1000–2000 Wh | Margin for a second night and other devices |
Model shortlists, computed from the dataset
Full Longest service life ranking →Because medical & cpap backup buyers are buying longest service life more than anything else, these shortlists are that ranking filtered to each capacity band above. They are computed from the same verified specs as the rest of the site, not picked by hand.

Reference runtimes
Runtime assumes 85% inverter efficiency and 90% usable depth of discharge, so a 1,000 Wh unit provides roughly 765 Wh of usable AC energy. Vendor figures differ; adjust for your own unit.
| Load | Typical draw | 500 Wh | 1,000 Wh | 2,000 Wh | 4,000 Wh |
|---|---|---|---|---|---|
| CPAP, no humidifier, no heated tube Typical average draw | 30 W | 13 h | 26 h | 51 h | 102 h |
| CPAP with humidifier Average over a night | 60 W | 6.4 h | 13 h | 26 h | 51 h |
| CPAP with humidifier and heated tube Highest common configuration | 90 W | 4.3 h | 8.5 h | 17 h | 34 h |
| Oxygen concentrator (portable) Varies widely by model | 120 W | 3.2 h | 6.4 h | 13 h | 26 h |
Mistakes to avoid
- Sizing for the CPAP without the humidifier, then using the humidifier
- Buying a single-night battery and having no margin for a second night
- Assuming an AC inverter is the most efficient path — DC is usually better
- Forgetting the device may need a specific DC adapter cable
