Within this system, the module serves as an energy storage unit that transfers direct current to the main device's inverter for subsequent conversion to either alternating or direct current. When used independently, this module functions as a powerful power bank, delivering energy through its built-in low-voltage USB-C port with Power Delivery 3.1 technology up to 140W, allowing the charging and powering of mobile gadgets and laptops with a USB-C power port. The nominal capacity of the EcoFlow RIVER 3 Extra Battery EB300 module is 245Wh, providing enough power for 4-6 hours of operation for an average 15.6" laptop in surfing mode. The integrated BMS controller ensures optimal battery operation conditio...ns. The module's shell allows the charging station to be placed on top or beneath it, forming a stable vertical structure that saves space. The module does not have its own inputs and charges only as part of the charging station (up to 2 hours from a household outlet).
