EcoFlow DELTA 3 Max – Portable Power Station with 2048 Wh Capacity
The EcoFlow DELTA 3 Max expands the DELTA 3 series with increased storage capacity and power output. With a 2048 Wh battery capacity and 2400 W continuous output, it is suitable for demanding mobile applications as well as a reliable backup power solution for homes, workshops, or construction sites.
Despite its high performance, the power station remains compact and portable, allowing flexible use wherever independent power supply is required.
Power and Capacity
With a 2048 Wh storage capacity, the DELTA 3 Max can power multiple devices simultaneously – from consumer electronics to household appliances.
The continuous output of 2400 W and peak output of up to 4800 W also allow operation of devices with high startup power requirements.
Thanks to its compact design and weight of approximately 20 kg, the power station remains mobile and is ideal for camping, mobile work applications, or as a home backup solution.
Fast Charging and Flexible Power Input
The DELTA 3 Max supports multiple charging options:
-
AC charging up to 2300 W
-
Solar charging up to 500 W
-
Charging via vehicle connection or generator
Via the AC power input, the power station can reach up to 80% charge in approximately 51 minutes and is quickly ready for use again.
Versatile Connections
For simultaneous operation of multiple devices, the following connections are available:
-
4 × AC outlets (230 V)
-
3 × USB-C (up to 100 W each)
-
1 × USB-A (18 W)
-
1 × 12 V vehicle output
This allows both small electronic devices and more powerful appliances to be operated reliably.
Backup Power Function and Control
The integrated UPS function with a switching time of less than 10 ms ensures uninterrupted power supply during grid failures.
Via WiFi, Bluetooth, and the EcoFlow App, users can conveniently monitor and control the charge level, input and output power, and operating modes.
An integrated display provides all important system information directly on the device.
Long-Life Battery Technology
The integrated LiFePOâ‚„ battery (LFP) with CTC technology offers a long service life, stable performance, and increased safety.
The power station is designed for operation across a wide temperature range and for mobile applications.
The EcoFlow DELTA 3 Max is a powerful and flexible power station for users who require more capacity than the DELTA 3 while still valuing portability and rapid availability.
