The EcoFlow Smart Generator Adapter lets you connect your EcoFlow DELTA Pro 3 or DELTA Pro system to EcoFlow Smart Generators—including the Smart Generator, Smart Generator (Dual Fuel), and Smart Generator 4000 (Dual Fuel). It plugs directly into the Extra Battery Port to provide a clean, reliable interface between the generator and your power station.

It’s also required when using the EcoFlow Alternator Charger with DELTA Pro 3 or DELTA Pro. Whether you’re charging from a vehicle alternator while driving or topping up with a Smart Generator during outages, this adapter ensures the connection is safe, compatible, and fully supported.

Use it to extend runtime for home backup, RV travel, overlanding, off-grid cabins, or job sites where solar and grid power aren’t always available. If you depend on the DELTA Pro ecosystem, this small accessory is what ties the whole system together.
