EcoFlow Delta Pro 3 4096Wh Portable Power Station

The EcoFlow Delta Pro 3 is a UL9540-certified portable power station built for homeowners and outdoor users who need dependable backup power. With a 4096Wh LiFePO4 (LFP) battery that can expand up to 48kWh, it delivers whole-home backup capability without the noise, fumes, or maintenance of a traditional generator.

Whether the goal is riding out a grid outage or running high-draw appliances off-grid, the Delta Pro 3 provides 4000W of continuous AC output, scalable to 6000W with X-Boost technology and up to 12000W peak. A 10ms UPS auto switch-over keeps sensitive electronics like routers, medical devices, and computers running without interruption.

Everyday use is simple through the EcoFlow App, which allows remote monitoring and control of charging, output, and battery status from anywhere.
