3072Wh of Dependable, Quiet Power — Ready When It Matters Most
The EcoFlow DELTA 3 Ultra (3072Wh) is a high-capacity portable power station engineered for home backup, off-grid living, and demanding outdoor use. Built on automotive-grade LFP cells with an EV-style cell-to-chassis (CTC) structure, it delivers 3600W rated AC output — and up to 4600W with X-Boost™ 3.0 technology — through four flexible charging methods including wall, solar, generator, and alternator. With whisper-quiet operation at ≤25dB and a 10ms auto-switch UPS function, it keeps sensitive electronics and critical devices running without interruption.
Note: EcoFlow Smart Generators and Solar Panels are sold separately. Solar charge time of ~9.6 hrs (400W Solar Panel bundle) is based on optimal conditions.
