EcoFlow DELTA Pro 3 | 4000W 120V/240V Portable Power Station | Expandable to 48kWh | Fast Solar & Generator Charging | LFP Battery Designed for homeowners, off-gridders, emergency-ready families, and job site power tools, the EcoFlow DELTA Pro 3 portable power station delivers 4,000W of clean power with true 120V/240V output. Whether you're riding out a blackout or living off-grid, it runs the appliances that matter most. Expandable Capacity up to 48kWh True 120V/240V Output Fast Charging (0–80% in 50 Minutes) About the Product Starting at 4kWh storage capacity and expandable to 48kWh through modular batteries, EcoFlow DELTA Pro 3 portable power station adapts to any situation—short outages or off-grid living. Setup is plug-and-play; no permits, no electrician, no waiting. The dual-voltage architecture is what sets it apart from the competition. With 4,000W continuous output, boosted to 6,000W via X-Boost technology, it handles both 120V everyday devices and heavy-duty 240V loads simultaneously. This means your refrigerator, medical equipment, sump pump, and central A/C stay running without interruption. Recharging is equally capable. X-Stream fast charging takes the unit from empty to 80% in just 50 minutes via AC wall outlet, solar input, or a car. When paired with EcoFlow's Smart Generator 4000, the power station enables hybrid fuel-plus-battery operation for extended outages—all with uninterrupted pass-through power to connected devices. Given the whisper-quiet X-Quiet technology, the DELTA Pro 3 power station is designed to run silently in living spaces. However, the IP65-rated enclosure, wide all-terrain wheels, and telescoping handle make it rugged enough for outdoor use and easy enough to move solo.
