EcoFlow Introduces Smaller, Higher-Density River Gen4 Portable Power Stations
Key points
- EcoFlow released River 260 Gen4 (256Wh) and River 520 Gen4 (512Wh) power stations.
- New models feature LFP battery chemistry for increased lifespan and safety.
- They offer higher energy density, reducing size and weight compared to predecessors.
- Both models include a 140W USB-C PD3.1 port and UPS functionality.
New River Gen4 Series Announced
EcoFlow has unveiled its fourth-generation River series of portable power stations, including the River 260 Gen4 and River 520 Gen4. These new devices are designed to be more compact and lighter while offering comparable or increased power capacities.
Enhanced Battery Technology and Capacity
The River 260 Gen4 has a 256Wh capacity, and the River 520 Gen4 offers 512Wh. Both models utilize LFP (Lithium Iron Phosphate) battery chemistry, which provides a longer lifespan and improved stability compared to previous generations. This chemistry also contributes to the higher energy density, allowing more power to be packed into a smaller physical size.
Connectivity and Features
The River 260 Gen4 includes four USB ports and one AC jack with a 300W continuous output. The River 520 Gen4 features the same USB port selection but offers two AC jacks for a 500W continuous output. Both power stations are equipped with a 140W USB-C PD3.1 port that supports bidirectional charging, eliminating the need for a separate charging brick. They also function as an uninterruptible power supply (UPS) with a cutover time under 10ms.
Availability
The River 260 Gen4 is scheduled for release in Europe in Q4 2026, with the River 520 Gen4 following in Q1 2027. Pricing details for both models will be announced closer to their global release dates.
