A New Era of Power Performance

Industry-Leading 3600W Rated Output with 7200W Surge and Smart Output Priority

Extend runtime for your essentials and stay powered through anything.

™ 3.0 Tech

When in bypass mode and connected to the grid or generator to power appliances via an AC outlet, X-Fusion overrides grid/generator electricity with inverter power—achieving a maximum power output of 3600W for DELTA 3 Ultra Plus.

Unlike other portable power stations limited by 1800W grid input when charging, you get higher power for your appliances, enjoying full 3600W output at all times.

Run Outdoor Gear. Power Your RV. Charge Your Essentials — One Station Powers it All

Cut Costs, Not Comfort

DELTA 3 Ultra Plus intelligently optimizes energy usage to help lower your electricity bills while powering your home sustainably. Set automated tasks to charge during off-peak evening hours and discharge during the day.

TOU Mode

Charge During Off-Peak, Use During Peak TOU Mode lets you set custom charging and discharging schedules based on your local electricity rates. Charge when energy is cheapest, and discharge during peak hours to cut costs without lifting a finger. ^[16]

Self-Powered

Reduce Grid Dependency, Lower Electricity Costs Self-Powered mode stores solar energy and powers your home once battery levels exceed a preset reserve. It minimizes grid use while maximizing solar efficiency—ideal for managing fluctuating energy prices and enhancing your energy independence.

TOU Mode in the EcoFlow app will be available soon. Please refer to the EcoFlow app for details on feature availability.

A New Standard of Reliability

10 Years of Reliable Power, Engineered from Cell to Unit

Delivering safe and dependable power through everyday use and outages

Automotive-grade Full-Tab LFP Cells: Next-Level Battery Reliability

DELTA 3 Ultra Plus is equipped with automotive-grade full-tab LFP cells. The full-tab design reduces resistance, enhances efficiency and safety, and provides higher capacity with less heat, resulting in a long battery lifespan.

25% more

efficient power flow (thanks to lower resistance: 1.5 mΩ vs. 2 mΩ) ^[17]

25% less

self-heating ^[18]

Unrivaled Balance for Unmatched Battery Longevity

With 27% fewer cells per kWh, ^[19] our 16-cell design runs cooler, lasts longer, and delivers greater stability. Each cell is rigorously tested for capacity, voltage, and internal resistance—resulting in a highly uniform pack that protects against overcharging, imbalance, and premature wear.

16-cell uniform set per 1 kWh

Rigorously tested for capacity, voltage, and internal resistance

Built to Last

Certified to UL 2743 standards and verified by SGS, ensuring electrical, mechanical, thermal management, and battery safety across a wide range of use scenarios. From battery chemistry to structural design, DELTA 3 Ultra Plus is engineered for extreme durability, environmental resilience, and whisper-quiet performance—delivering power you can count on for over 10 years. ^[2]

Smart, 24/7 Battery Protection

EcoFlow’s advanced BMS uses a high-performance ARM Cortex chipset and intelligent algorithms to monitor your battery in real time. By tracking SOC, SOH, temperature, and more, it ensures peak performance, extended battery life, and worry-free operation.

EV-Grade CTC Structure

Built with a cell-to-chassis (CTC) structure, DELTA 3 Ultra Plus (3072Wh) is drop-resistant (0.2m) —protecting against overnight condensation and off-road bumps during transport. You get stable power even in the most demanding conditions. ^[20]

Extreme Environment Resistance

DELTA 3 Ultra Plus (3072Wh) keeps your power flowing through freezing cold, scorching heat, humid environments (95% humidity tolerance), or coastal air (5% salt spray resistance). ^[20]
