EcoFlow AC Generator Charging Adapter for DELTA Pro Ultra

EcoFlow AC Generator Charging Adapter (DELTA Pro Ultra)

If you already own a generator with a NEMA L14-30R outlet — which covers most portable 240V generators — this adapter lets it charge your DELTA Pro Ultra directly. That matters during a long outage: solar stops at sunset, but a generator can refill the battery bank at any hour.

It's purpose-built for the DELTA Pro Ultra rather than a generic adapter, so the connection is secure and the handshake between generator and inverter behaves as EcoFlow intends.

  • Works With Standard L14-30R Generators: Connects any generator with a NEMA L14-30R outlet to your DELTA Pro Ultra.
  • Purpose-Built: Designed specifically for the DELTA Pro Ultra rather than adapted from a generic part.
  • Extends Outage Coverage: Recharge the battery bank overnight or in poor weather when solar can't.
  • Extension Available: Pair it with EcoFlow's NEMA L14-30R to L14-30P generator cord (4.9 ft / 1.5m) if you need extra reach.

Renewable Outdoors is an authorized EcoFlow dealer. Our Lowest Price Guarantee applies to every order — call us at (303) 876-7654 if you're unsure which part fits your setup and we'll check it for you.
