The EcoFlow DELTA 3 Max Plus is a 2,048 Wh portable power station that can be scaled up to 10,240 Wh with extra batteries, weighing about 22.1 kg and measuring 49.4 × 24.2 × 30.5 cm. Its four AC outlets provide 3,000 W of continuous pure sine power with peaks up to 6,000 W and X-Boost up to 3,900 W, so higher-draw tools and appliances that a 2 kW class station would refuse can still run. UPS switchover under 10 ms with HID keeps sensitive workloads safe during outages, and X-Stream fast charging refills the pack in about 1.1 hours or 80% in 47 minutes.

• 2,048 Wh LiFePO4 storage, expandable up to 10,240 Wh with additional batteries
• 4 × 230 V AC outlets at 3,000 W (peak 6,000 W), pure sine, plus X-Boost up to 3,900 W
