EcoFlow DELTA Pro 3 Portable Power Station with 4000W Output, 120/240V Split-Phase, LFP Battery, and X-Stream Fast Charging

The EcoFlow DELTA Pro 3 is a premium flagship portable power station designed for homeowners who need serious whole-home backup capability with the flexibility to scale from a single-unit essential backup all the way up to a multi-day whole-home energy system. Starting with 4,096Wh of automotive-grade LiFePO4 battery capacity and 4,000W of AC output supporting both 120V and 240V, it handles virtually every major home appliance including 3-ton central air conditioning units, water heaters, well pumps, refrigerators, and power tools without limitation. X-Boost technology extends effective output to 6,000W for high-draw appliances, and connecting two additional units in parallel scales total output to 12,000W for simultaneous operation of multiple heavy loads across an entire household.

Expandability is one of the DELTA Pro 3’s most compelling strengths, with capacity growing from 4,096Wh up to 48kWh through a combination of extra battery packs and smart generators, providing two to four days of whole-home backup power from a single system. Recharging is equally versatile, with 18 total charging method combinations supported including AC wall outlets, solar panels at up to 2,600W combined input, EV charging stations, gas generators, and the EcoFlow Smart Home Panel 2. Fast charging from AC wall power brings the unit from empty to 80 percent in approximately 50 minutes, and the IP65-rated CTC battery pack technology provides dust-tight and rain-resistant protection for reliable outdoor use. A 10 millisecond UPS switchover time ensures NAS systems, servers, desktop computers, and entertainment devices stay running without any interruption the moment grid power cuts out.

EcoFlow’s X-Quiet technology keeps operating noise as low as 30 decibels, making it genuinely suitable for indoor use including bedroom placement during overnight outages. The EcoFlow app provides comprehensive remote monitoring and control via Wi-Fi or Bluetooth, and the new Oasis AI feature optimizes charging and discharging by learning household usage patterns while factoring in energy costs and weather forecasts for maximum efficiency and bill savings. Larger wheels compared to the original DELTA Pro improve mobility across rougher surfaces like gravel and uneven flooring, and a telescoping handle makes repositioning the 115-pound unit more manageable.
