For CPAP users, a power outage isn't an inconvenience — it's a medical problem at 2 AM. The good news is that CPAPs are tiny loads (30–90W), which makes silent battery power the perfect solution: no noise outside your window, no midnight refueling, no carbon monoxide anywhere near a sleeping household.

With the humidifier off, a CPAP draws roughly 30–60W — call it 300–500Wh per 8-hour night. A 2,000Wh station covers 4–6 nights; with heated humidification, expect 1–2 nights.
Yes. CPAP power supplies want clean sine-wave AC (or native DC input). All battery power stations and inverter generators qualify; older open-frame generators may not.
