Description
If you’re looking for a portable power station that can handle home backup, off-grid adventures, and emergency preparedness all at once, the EcoFlow DELTA 3 Ultra (3072Wh) delivers on every front. With 3,072Wh of built-in LiFePO4 capacity and 3,600W of AC output, this powerhouse is built to run the appliances that matter most — refrigerators, air conditioners, power tools, medical devices, and more — without breaking a sweat.
What sets the DELTA 3 Ultra apart is its combination of raw power and intelligent output management. Powered by X-Boost™ 3.0 technology, it can support devices drawing up to 4,600W, well beyond its rated output. A high-precision DSP chip samples AC voltage and current every 33 microseconds, producing a pure sine wave output with grid-level stability — meaning your sensitive electronics like computers, medical equipment, and home theater systems are fully protected. The 10ms UPS auto-switch kicks in seamlessly during power outages, so your connected devices never lose power.
Charging the DELTA 3 Ultra is fast and flexible. With AC input, it reaches 0–80% in approximately 89 minutes, and EcoFlow’s Storm Guard Mode can automatically trigger AC charging remotely when severe weather alerts are detected — ensuring you’re always prepared before a storm hits. Solar charging is supported up to 800W, making it a true off-grid solar generator for camping, van life, and remote worksites. You can also charge via car or a compatible EcoFlow Smart Generator for unlimited runtime during extended outages.
Built to last, the DELTA 3 Ultra features a cell-to-chassis (CTC) structure that is drop-resistant and shockproof, with 95% humidity tolerance and all-weather reliability. Its LFP battery is rated for over 3,000 cycles with more than 10 years of lifespan, while an ARM Cortex-powered BMS monitors battery health in real time. Expandable to 5kWh with compatible Smart Extra Batteries, app-controlled via the EcoFlow app, and backed by a free 5-year warranty — this is portable backup power designed to serve you for the long haul.
