The EcoFlow Delta 2 Max heralds a new era of portable energy solutions, combining performance and sustainability in one innovative product. With a breathtaking capacity of 2048 Wh—which can be easily expanded to up to 6144 Wh by adding additional batteries—the Delta 2 Max offers unparalleled flexibility and reliability for all your energy needs, whether for everyday life or your next big adventure.

Equipped with a state-of-the-art lithium iron phosphate (LFP) battery, the Delta 2 Max offers an impressive 10-year lifespan, making it a long-lasting and reliable power source. With an AC output of 2,400 W, it can power nearly any device—from smartphones and laptops to more demanding appliances like refrigerators (not intended for life-critical medical devices, see user manual).

The innovative X-Stream technology enables exceptionally fast charging—from 0 to 100% in just 80 minutes at a maximum power of 2,300 W. In addition, the Delta 2 Max can be fully charged using solar power in just 2.3 hours, thanks to its two solar ports, each rated at 500 W (for a total of 1,000 W). These features make it easy to harness sustainable energy sources and maximize independence from the power grid.

With a noise level of less than 30 dB, the Delta 2 Max remains surprisingly quiet even at high power output, making it ideal for use in any environment. The integration of smart app control via Wi-Fi or Bluetooth allows you to monitor and adjust the power station to optimize energy consumption and maximize the Delta 2 Max’s performance.

The EcoFlow Delta 2 Max thus offers not only a portable but also a reliable and powerful energy solution for all your needs. Discover the freedom and independence of an advanced power supply with the Delta 2 Max.
