Power Compatible Appliances Up to 4600W
EcoFlow's X-Boost technology supports compatible appliances up to 4600W, giving the DELTA 3 Ultra Plus additional flexibility when operating high-wattage equipment. This allows selected appliances that exceed the standard 3600W output rating to be powered under suitable conditions.
Ready in Just 48 Minutes
The DELTA 3 Ultra Plus supports multiple charging methods and can reach 0–80% in approximately 48 minutes when using EcoFlow's specified solar + Smart Generator dual-charging setup. This high-speed charging capability helps minimize downtime during emergencies and extended trips.
Up to 1600W Solar Charging
Harness clean renewable energy with up to 1600W of solar input. Connect compatible solar panels to recharge the DELTA 3 Ultra Plus while camping, traveling, or operating off-grid. High solar input allows you to take advantage of available sunlight and replenish the large 3072Wh battery more efficiently.
Six Flexible Ways to Recharge
The DELTA 3 Ultra Plus supports six charging methods, giving you flexibility at home and on the road. Recharge using AC power, solar energy, a compatible Smart Generator, and other supported charging configurations. This makes it easier to maintain your power supply even when conventional grid electricity is unavailable.
Expandable from 3kWh to 11kWh
Start with 3072Wh of built-in capacity and expand the system to as much as 11kWh using compatible expansion batteries. EcoFlow states that the DELTA 3 Ultra Plus can reach up to 11kWh with two DELTA Pro 3 Extra Batteries, providing significantly longer runtime for extended home backup and off-grid applications.

The DELTA 3 Ultra Plus uses EV-grade full-tab LiFePO₄ (LFP) battery cells designed for long-term reliability. EcoFlow states that the battery platform is engineered to deliver 10 years of reliable power under its specified conditions. LFP chemistry also provides excellent thermal stability and is well suited to frequent charging and discharging.
Professional <10ms UPS Backup
Protect important electronics against unexpected power interruptions with the built-in <10ms UPS function. When connected to an appropriate AC source, the DELTA 3 Ultra Plus can rapidly switch to battery power when utility electricity fails. This makes it useful for computers, networking equipment, NAS systems, home offices, and other sensitive electronics.

140W USB-C Fast Charging
The integrated 140W USB-C port provides high-power charging for compatible laptops, tablets, cameras, gaming devices, and other USB-C equipment. Two additional USB-C ports provide up to 45W each, while the USB-A port provides up to 18W.
High-Power 12V DC Output
For RV and automotive applications, the DELTA 3 Ultra Plus provides a 378W 12V DC output through its Anderson connection and a 126W car power outlet. These outputs are useful for compatible refrigerators, pumps, vehicle accessories, and other DC equipment.

Smart energy-management features make it easier to optimize available power and monitor your system remotely.
24/7 Intelligent Battery Protection
An advanced Battery Management System (BMS) continuously monitors important battery parameters to help protect the system during charging and discharging. EcoFlow highlights a BMS powered by an ARM Cortex chipset and cloud-intelligence algorithms, providing intelligent monitoring and protection.
Built for Long-Term Durability
The DELTA 3 Ultra Plus is designed around EV-grade full-tab LFP battery technology and a durable structural design. EcoFlow states that the platform has been tested and verified by UL and SGS, supporting its focus on long-term reliability and safety.
Quiet Operation for Home and Outdoor Use
The DELTA 3 Ultra Plus incorporates EcoFlow's X-Quiet 3.0 technology, which uses stepless fan control to adjust airflow according to operating conditions. This helps maintain thermal performance while reducing unnecessary fan noise, making the unit more comfortable to use in homes, offices, RVs, and campsites.
3–11kWh Power That Grows With You
The DELTA 3 Ultra Plus is more than a standalone portable battery. Its expandable architecture allows the system to grow from 3kWh to up to 11kWh, making it suitable for users who may require additional backup capacity in the future. EcoFlow also supports Smart Generator integration for extended runtime.
