The EcoFlow Delta Max is a portable, environmentally friendly power supply for the set. You can deliver 1800 W of power with the Deta. In addition, you have 4 earthed sockets, a 12V cigarette lighter socket, and USB A and USB-C outputs on the device. The capacity of the device is 2016Wh. A 100% charge via electricity takes 1.6 hours. Via solar panel, you can charge the Delta in 4 hours if you use 4 110W modules. Less solar panels will increase the charging time. The system can be charged via the supplied mains cable or via a solar panel, which can be ordered separately. We are currently testing the runtimes with different consumers and will list the values here. The Delta Max is ideal for laptop or Digi-workstation applications, but also LED systems such as Skypanels, Orbiters, and Aputure's run easily and quietly via the Delta Max.
