EcoFlow Launches Smaller, More Efficient Power Stations with Higher Energy Density
EcoFlow has introduced the fourth-generation River series of portable power stations that offer significantly higher energy density in a more compact and lightweight design. The new models—River 260 Gen4 (256Wh) and River 520 Gen4 (512Wh)—utilize LFP battery chemistry for improved safety and longevity, while maintaining high output capabilities through USB ports and AC jacks. Compared to similar products from competitors like Anker and Bluetti, EcoFlow’s new models deliver superior volumetric energy density. The River 520 Gen4 can power a standard US fridge for about four hours during an outage, making it suitable for short-term backup needs or outdoor activities such as camping. The River 260 Gen4 will be available in Europe by Q4 2026 and the River 520 Gen4 is expected to launch globally early next year. Both models support fast USB-C PD3.1 charging, reducing reliance on traditional power bricks.
