The Checks, One by One
| Check | Result | Detail |
|---|---|---|
| Pure sine wave | ✅ pass | Inverter is confirmed pure sine wave, which this appliance requires. |
| Running watts | ✅ pass | 1000W continuous output covers the appliance's 30W running draw, leaving 970W of headroom. |
| Runtime | ℹ️ info | 768Wh of battery at a 75% AC-inverter efficiency factor gives roughly 19.2 hours of continuous running at 30W. |

How Long It Would Run
At a continuous 30W draw, the Bluetti AC70's 768Wh battery gives roughly 19.2 hours after accounting for a 75% AC-inverter efficiency factor.
About This Appliance
Figure is for a CPAP running without its heated humidifier. A CPAP's internal power supply converts AC back to DC, so a confirmed pure sine wave inverter is a hard requirement.

Methodology
Verdict computed from this project's verified entity data using the same gates as its use-case scoring: waveform requirement first (an unconfirmed inverter type fails rather than passing), then continuous watts, then startup surge, then runtime at a 75% AC-inverter efficiency factor. Entity specs verified 2026-09-13; appliance figure from data/use-cases/cpap.json (draw_scenarios_w.no_humidifier).
