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
What size generator for a food truck?
For a typical setup (refrigerator (bottom-freezer, ~20 cu ft), induction cooktop (portable single burner), coffee maker, router + modem and led bulb (60w equivalent)), you need at least 5,077W of continuous power. The single biggest moment is startup: when 1× box fan kicks on, the momentary draw peaks at 5,477W. For overnight runtime we recommend at least 9,450Wh of battery capacity (your devices use about 7,560Wh per day, plus a 25% margin).
Which power stations can handle this?
Look for a station whose surge rating covers 5,477W and whose capacity is at least 9,450Wh.
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.
