EcoFlow does not provide a single universal wattage for these appliances because consumption varies by model and operating mode. Check each appliance’s own rating and do not treat the runtime examples as a guarantee.

Who Is It For?

The DELTA 3 may suit households needing short-term backup for selected appliances, campers, van users and people working away from fixed power. Before connecting a device, check its running wattage and start-up surge against the station’s limits. It is not automatically a substitute for a permanently installed home battery or a whole-house backup system.

Risks, Care and Maintenance

Keep the unit dry and use it only within the temperature and environmental limits in the official manual.
Do not exceed the AC output or solar-input limits, and use compatible charging cables and panels.
For refrigerators, pumps and other motor-driven equipment, allow for start-up surge and check compatibility.
Inspect cables and connectors regularly; stop using damaged accessories.
Store and recharge the battery according to EcoFlow’s current instructions. Avoid leaving the unit in excessive heat or freezing conditions.
Do not connect the power station to household wiring or attempt a fixed installation without qualified professional advice and compliant equipment.
