2. Your sizing
⚠️ For medical devices (CPAP, oxygen concentrator) check the manufacturer's inverter waveform requirement (usually pure sine wave) and verify with your equipment supplier. Verify nameplate watts and starting amps before buying; consult a licensed electrician for fixed wiring.
Assumptions: daily hours per device follow DOE / ENERGY STAR duty cycles; capacity adds a 25% margin. Check your appliance nameplates — actual draw varies by model.

Frequently asked questions
What size generator do I need for cpap camping?
For a typical setup (CPAP Machine (ResMed AirSense 11, with humidifier), Phone / Smartphone Charger, Portable 12V Fridge/Freezer (Dometic CFX3 45 class) and LED Bulb (60W equivalent)), you need at least 185W of continuous power. The single biggest moment is startup: when 1× portable 12v fridge/freezer (dometic cfx3 45 class) kicks on, the momentary draw peaks at 385W. For a full day of runtime we recommend at least 1,400Wh of battery capacity (your devices use about 1,113Wh per day, plus a 25% margin for a full day of use).
Which power stations can handle this?
Based on published specs, Anker SOLIX F1500, EcoFlow DELTA 3 Max, EcoFlow DELTA 3 Max Plus cover the 385W startup peak and deliver 1.4 days / 1.8 days / 1.8 days of typical daily use. Check the comparison cards above for the full numbers.
Why is the startup surge higher than the running watts?
Motor-driven devices (fridge compressors, well pumps, air conditioners) draw 2-5× their running power for a split second at startup — measured as locked-rotor amps (LRA). On this page the biggest spike comes from the Portable 12V Fridge/Freezer (Dometic CFX3 45 class): a station that only meets the running load will trip or stall when it starts.
