The Ecoflow Delta Max powered station is distinguished from the basic models in the line by its ability to expand its battery capacity with an additional battery. The additional Ecoflow Delta Max battery allows you to double your power supply, giving you as much as 3600 Wh of energy to use when working in the field. Like the station, the additional battery is characterized by its compact size, so we will get an easy-to-transport and easy-to-store set providing an extremely large reserve of energy.
