Frequently asked questions

What size generator do I need for camping?

For a typical setup (Portable 12V Fridge/Freezer (Dometic CFX3 45 class), Phone / Smartphone Charger, LED Bulb (60W equivalent) and Box Fan), you need at least 228W of continuous power. The single biggest moment is startup: when 1× portable 12v fridge/freezer (dometic cfx3 45 class) kicks on, the momentary draw peaks at 428W. For a full day of runtime we recommend at least 1,790Wh of battery capacity (your devices use about 1,430Wh 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 428W startup peak and deliver 1.4 days / 1.4 days / 1.4 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). On this page the biggest spike comes from the Portable 12V Fridge/Freezer (Dometic CFX3 45 class): a station that only meets the running load will trip or stall when it starts.
