EcoFlow DELTA 3 Max is designed to reliably power a wide range of devices. The system provides high and stable AC output power, suitable for household appliances for everyday use in a home environment, work equipment and sensitive electronics, or as a backup power source.

Due to its performance and flexibility, the device is suitable for a wide range of applications, both in the home and in professional environments:

• Backup power supply at home – refrigerators , basic household appliances, network equipment, and lighting
• Simultaneous power supply for multiple devices – computers , monitors, televisions, and smaller appliances
• Mobile and professional workstations – including power tools, measuring equipment, and other work equipment
• Environments without a reliable power grid – where high and stable output power is required

High output power

The device provides2400 W of nominal AC output power and up to4800 W of starting power, enabling reliable operation of devices with higher starting currents. It is suitable for powering household appliances, work equipment, and electronic devices.

Precise AC output control

The built-in inverter uses high-precision voltage and current control. Sampling takes place every 33 μs, ensuring stable output and power quality comparable to the mains supply. This type of output is also suitable for sensitive electronic devices.

5 charging modes

• AC charging: fast charging with X-Stream technology – 0-80% in 47 minutes

• Solar charging: support for charging with solar energy – 95 minutes – 0-80% in 96 minutes

• Alternator charging: charging option while driving or off-road – 0-80% in 95 minutes

• Generator charging: suitable for use without access to the grid – 0-80% in 47 minutes

• Simultaneous solar + alternator charging: faster charging using multiple energy sources at the same time – 0-80% in 51 minutes

Smart output power management

The system allows you to manage the distribution of output power according to the connected devices. The app can be used to set priorities for individual outputs, allowing key devices to operate for longer, even when the user is not present.
