Frequently asked questions
generator for jobsite with air compressor?
For a typical setup (air compressor (4.2 gal twin-stack), circular saw (7-1/4 inch), drill (1/2 inch), shop vacuum (6 gallon, 3.5 peak hp) and led bulb (100w equivalent)), you need at least 4,142W of continuous power. The single biggest moment is startup: when 1× air compressor (4.2 gal twin-stack) kicks on, the momentary draw peaks at 7,062W. For overnight runtime we recommend at least 2,450Wh of battery capacity (your devices use about 1,958Wh per day, plus a 25% margin).
Which power stations can handle this?
Based on published specs, Bluetti AC200L, Anker SOLIX F3800, EcoFlow DELTA Pro 3 all cover the 7,062W startup peak and give you 1.0 days / 2.0 days / 2.1 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.
