Frequently asked questions
solar generator 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 189W 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 389W. For overnight runtime we recommend at least 1,420Wh of battery capacity (your devices use about 1,133Wh per day, plus a 25% margin).
Which power stations can handle this?
Based on published specs, Goal Zero Yeti 1500X, Anker SOLIX F1500, Bluetti AC200L all cover the 389W startup peak and give you 1.3 days / 1.4 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). A generator that only meets the running load will trip or stall when the biggest motor starts.
