xEcoFlow DELTA 3 Ultra Portable Power Station (3072Wh)
3072Wh Capacity | 3600W Output | 7200W Surge | 4600W X-Boost | 800W Solar Input | <10ms UPS | LiFePO₄ Battery
The EcoFlow DELTA 3 Ultra Portable Power Station (3072Wh) delivers powerful, reliable energy for home backup, emergencies, RV travel, camping, workshops, outdoor activities, and demanding everyday applications. With a substantial 3072Wh capacity, 3600W continuous AC output, and up to 7200W surge power, it can handle a wide range of household appliances and high-demand equipment. EcoFlow's X-Boost technology supports compatible appliances up to 4600W, while automotive-grade LiFePO₄ cells, rapid charging, <10ms UPS protection, smart energy management, and quiet operation make the DELTA 3 Ultra a powerful long-term energy solution.
3kWh of Reliable Energy Storage
With 3072Wh of battery capacity, the DELTA 3 Ultra provides a large energy reserve for extended power outages and off-grid adventures. Keep essential appliances, electronics, networking equipment, lighting, entertainment systems, and other compatible devices operating for longer without frequent recharging. The 3kWh-class capacity makes it particularly suitable for homeowners who need more than a typical 1kWh portable power station can provide.
3600W Powerful AC Output
The DELTA 3 Ultra delivers 3600W of continuous AC output with up to 7200W of surge power. This high output allows you to run multiple demanding appliances simultaneously while providing stable pure sine wave power for compatible sensitive electronics.
Power Heavy-Duty Appliances with 4600W X-Boost
EcoFlow's X-Boost technology supports compatible appliances up to 4600W, giving the DELTA 3 Ultra the ability to handle many high-wattage appliances beyond its standard rated output. EcoFlow highlights applications including electric dryers, lawnmowers, clothing steamers, and electric frying pans, making it suitable for demanding home, workshop, and outdoor applications.
Recharge from 0–80% in Just 89 Minutes
Get your backup system ready quickly with EcoFlow's X-Stream fast-charging technology. The DELTA 3 Ultra can recharge from 0% to 80% in approximately 89 minutes using wall or compatible generator charging under EcoFlow's specified test conditions. This helps minimize downtime after a power outage or between outdoor trips.
Harness Clean Solar Energy
The DELTA 3 Ultra supports up to 800W of solar input, allowing you to replenish the battery using compatible solar panels. Solar charging provides a clean and renewable way to maintain your power supply during camping, RV travel, emergencies, and extended off-grid use.
Four Flexible Ways to Recharge
The DELTA 3 Ultra supports multiple charging options, including AC wall charging, solar charging, generator charging, and vehicle/alternator charging with compatible EcoFlow equipment. This flexibility allows you to recharge at home, on the road, or in remote locations where traditional grid power may not be available.
Expandable Energy Storage
The DELTA 3 Ultra can be integrated into a larger EcoFlow energy system for increased storage capacity. EcoFlow lists compatibility with DELTA Pro 3 Extra Batteries, allowing the system to scale up to approximately 11kWh with two compatible expansion batteries. This makes the platform suitable for users whose backup requirements may grow over time.
Long-Lasting Automotive-Grade LiFePO₄ Battery
Built with automotive-grade full-tab LiFePO₄ (LFP) cells, the DELTA 3 Ultra is designed for long-term reliability and repeated use. EcoFlow estimates a lifespan of approximately 10 years under proper usage, based on internal simulation testing. The advanced battery management system continuously monitors the battery to help optimize performance and safety.
24/7 Intelligent Battery Protection
The DELTA 3 Ultra uses an advanced battery management system (BMS) with intelligent monitoring to track important parameters such as battery state of charge, state of health, and temperature. This helps maintain safe and efficient operation while supporting long-term battery performance.
Professional <10ms UPS Backup
The built-in <10ms UPS function helps protect critical electronics from sudden power interruptions. When connected to a suitable AC power source, the DELTA 3 Ultra can rapidly switch to battery power when utility electricity fails, making it useful for computers, networking equipment, NAS systems, home offices, and other sensitive electronics.
Stable Pure Sine Wave Power
The DELTA 3 Ultra uses an advanced inverter and digital signal processing system to provide stable pure sine wave AC power. EcoFlow states that the system samples AC voltage and current at high precision, helping deliver stable power suitable for household appliances and sensitive electronics.
Whisper-Quiet Operation
Despite its powerful output, the DELTA 3 Ultra is designed for quiet operation. EcoFlow specifies noise levels of approximately 25dB at a 600W load under its testing conditions. This makes it suitable for homes, offices, RVs, campsites, and other environments where excessive noise can be disruptive.
X-Quiet 3.0 for Intelligent Cooling
The DELTA 3 Ultra features X-Quiet 3.0, EcoFlow's stepless fan-control technology. The system adjusts airflow according to thermal requirements to maintain stable operating temperatures while helping minimize unnecessary fan noise during charging and discharging.
Built for Demanding Environments
The DELTA 3 Ultra features an EV-grade cell-to-chassis (CTC) structure designed to provide additional protection against bumps and drops during transportation. EcoFlow also highlights resistance to challenging environments, including high humidity and coastal conditions, making the unit suitable for a broad range of indoor and outdoor applications.
Power Multiple Devices at Once
The DELTA 3 Ultra provides a wide selection of output ports for household appliances and personal electronics. The US version includes four 20A AC outlets and one 30A AC outlet, providing up to 3600W total AC output. It also includes USB-A, USB-C, and 12V DC outputs for charging and powering smaller devices.
140W USB-C Fast Charging
The integrated 140W USB-C port provides high-power charging for compatible laptops, tablets, gaming devices, cameras, and other USB-C equipment. Two additional USB-C ports provide up to 45W per port, while the USB-A output supports up to 18W.
Smart Control with the EcoFlow App
Connect the DELTA 3 Ultra through Wi-Fi and Bluetooth and manage your power station using the EcoFlow App. Monitor battery levels, energy consumption, charging activity, and solar generation from your smartphone. Supported smart-energy features also allow you to schedule charging and discharging according to your energy requirements.
Designed for Home Backup and Outdoor Adventures
