EcoFlow documents up to 3,200W direct DC charging, app control and automatic start/stop with specific compatible systems.
Charging a power station
Direct smart charging is documented for selected EcoFlow products and may require the DELTA Pro to Smart Generator Adapter. Other stations use ordinary AC charging only if their manuals allow it.
Practical caution

Buying checks for the United Kingdom
Regional electrical version: Match rated voltage, frequency, outlet layout, certification and model suffix to the delivery country. A travel adapter cannot turn a 120V generator into a 230V unit. Continuous and starting output: Size from ordinary running watts and the largest realistic starting event. Peak output is temporary and must not be treated as continuous capacity. Fuel, storage and service: Confirm the approved fuel, local storage rules, oil and maintenance schedule, warranty network and whether LPG hardware is factory supplied. Safe connection and placement: Operate combustion generators outdoors away from openings. Use approved cords or transfer equipment and never improvise backfeed into a building.
