Product Overview

The EcoFlow DELTA 3 Max provides a balance of high-capacity battery storage, strong AC output, fast charging, and portable design for home, work, travel, and outdoor applications.

Its 2048Wh capacity provides backup energy for compatible appliances and electronic devices during power interruptions or when mains electricity is unavailable. The unit delivers a 2400W continuous AC output and a 4800W surge output, allowing it to power selected refrigerators, televisions, computers, routers, kitchen appliances, tools, lights, and mobile work equipment within its operating limits.

EcoFlow’s X-Boost 3.0 technology can support selected compatible appliances rated up to approximately 3200W by reducing operating voltage where appropriate. X-Boost is best suited to selected resistive appliances and should not be treated as a replacement for the unit’s 2400W continuous rated output.

The DELTA 3 Max includes an automatic UPS switchover time of under 10 milliseconds. When installed and used correctly, it can help keep compatible computers, network equipment, NAS devices, communication systems, and selected electronics operating during a short mains interruption.

The automotive-grade full-tab LiFePO₄ battery cells, EV-grade cell-to-chassis structure, intelligent battery management system, Class B EMC certification, and X-Quiet 3.0 thermal management system support reliable long-term operation.

The DELTA 3 Max can be monitored and managed through the EcoFlow App using Wi-Fi or Bluetooth. Users can check battery status, monitor power consumption, schedule charging and discharging, configure selected operating settings, and access compatible energy-management features.

Runtime and charging performance will vary according to the connected load, charging source, battery level, environmental temperature, software settings, and operating conditions.

Important Power Compatibility Note

Please check the rated and starting power requirements of each device before connecting it to the DELTA 3 Max.

The unit provides a continuous rated AC output of 2400W. Appliances with motors, compressors, pumps, heating elements, or transformers may require significantly more power during startup.

The 3200W X-Boost rating applies only to selected compatible appliances. X-Boost may reduce operating voltage and is not recommended for voltage-sensitive equipment, precision electronics, selected compressors, or devices requiring stable full-voltage operation.

Runtime will vary depending on:

• Connected device wattage
• Appliance startup requirements
• Number of connected devices
• AC and DC conversion losses
• Battery level and battery condition
• Temperature and ventilation
• App settings and operating mode
• Charging or discharging conditions
