Frequently asked questions

What size generator for dj setup?

For a typical setup (Powered PA Speaker (12 in — QSC K12.2 class), Laptop Computer, Computer Monitor (27-inch LED), LED Bulb (60W equivalent) and Phone / Smartphone Charger), you need at least 580W of continuous power. The single biggest moment is startup: when 2× powered pa speaker (12 in — qsc k12.2 class) kicks on, the momentary draw peaks at 580W. For a full day of runtime we recommend at least 3,250Wh of battery capacity (your devices use about 2,596Wh per day, plus a 25% margin for a full day of use).

Which power stations can handle this?

Based on published specs, Anker SOLIX F3800, EcoFlow DELTA Pro 3, EcoFlow DELTA 3 (with expansion batteries) cover the 580W startup peak and deliver 1.5 days / 1.6 days / up to 1.9 days fully expanded of typical daily use. Check the comparison cards above for the full numbers.

Do any of these devices need extra startup power?

No — this selection (e.g. heaters, electronics, lighting) has no motor-driven devices, so the startup peak equals the running load (580W). Any station rated for the continuous load handles it. Note: if you add a fridge, pump or A/C unit in the calculator, its locked-rotor start (2-5× running power) will raise the peak.
