EcoFlow EB300 Extra Lithium Battery pack for River 3 Plus & River 3 Max

The EB300 Battery for RIVER 3 Plus from EcoFlow is designed to expand the overall capacity of the power station. The RIVER 3 Plus and the EB300 conveniently stack together, securely connecting to each other physically via clips, and wirelessly via pogo pins. Once together, the EB300 adds 286Wh of power capacity. However, the EB300 can also be used on its own, like a giant power bank. Devices can connect via a single USB-C port to receive up to 140W of power, the same port used to recharge the EB300. All of this power is provided by LiFePO 4 battery chemistry, which is designed to last for up to 10 years.
