Frequently asked questions

What size generator do I need for home office during outage?

For a typical setup (Desktop PC (under load), Computer Monitor (27-inch LED), Router + Modem, Laptop Computer and Printer (inkjet), plus 2 more devices), you need at least 299W of continuous power. The single biggest moment is startup: when 1× desktop pc (under load) kicks on, the momentary draw peaks at 299W. For a full day of runtime we recommend at least 2,020Wh of battery capacity (your devices use about 1,614Wh per day, plus a 25% margin for a full day of use).

Which power stations can handle this?

Based on published specs, EcoFlow DELTA 3 Max, EcoFlow DELTA 3 Max Plus, Jackery Explorer 2000 Plus cover the 299W startup peak and deliver 1.3 days / 1.3 days / 1.3 days 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 (299W). 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.
