No single portable power station covers this load — look at expandable systems (e.g., EcoFlow DELTA Pro 3 + extra battery, Anker SOLIX F3800 expansion packs) or a fixed home battery instead.

Frequently asked questions
generator for home oxygen machine?
For a typical setup (home oxygen concentrator (5 lpm class), refrigerator (top-freezer, ~16 cu ft), router + modem and led bulb (60w equivalent)), you need at least 441W of continuous power. The single biggest moment is startup: when 1× refrigerator (top-freezer, ~16 cu ft) kicks on, the momentary draw peaks at 691W. For overnight runtime we recommend at least 10,120Wh of battery capacity (your devices use about 8,090Wh per day, plus a 25% margin).
Which power stations can handle this?
Look for a station whose surge rating covers 691W and whose capacity is at least 10,120Wh.
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.
