EcoFlow has introduced its fourth-generation River series of portable power stations, focusing on smaller, lighter designs that still deliver substantial energy capacity. The lineup includes two models: the River 260 Gen4 with 256Wh and the River 520 Gen4 with 512Wh of battery storage.

According to the announcement, these new units significantly outperform earlier models in the energy-to-size ratio, making them appealing for users who need portable power without the bulk of larger generator systems.
