Our Review
The DELTA Pro 3 is less a 'portable' power station and more a home energy system that happens to be movable. With 4,000Wh of LiFePO4 capacity (expandable to a staggering 48kWh with extra batteries), 4000W output, and the ability to wire directly into your home breaker panel via an optional transfer switch, this is serious home backup power. It handles everything — fridges, HVAC, sump pumps, medical equipment. The EcoFlow app provides detailed energy management, and solar input accepts up to 2600W for off-grid living. At $1,699, it's an investment, but it replaces a gas generator permanently.
