EcoFlow RIVER 2 Series: Which Model Fits Your Mobile Power Needs?

Introducing the RIVER 2 Series


EcoFlow's RIVER 2 series offers portable power for different needs and budgets. All models share core features but differ in capacity and power output. Understanding these differences helps you choose wisely.


The series includes RIVER 2, RIVER 2 Pro, and RIVER 2 Max. Each serves specific use cases from light camping to serious backup power.


Core Features All Models Share


  • LiFePO4 Battery Technology
    All RIVER 2 models use lithium iron phosphate batteries. This means 3,000+ charge cycles, better heat resistance, and longer life than older battery types.
  • Fast Charging
    All models charge quickly. The RIVER 2 charges 0-100% in one hour. This is much faster than older portable power stations.
  • Pure Sine Wave Output
    Clean power safe for sensitive electronics like laptops and medical devices. No risk of damage from power quality issues.
  • Solar Ready
    All work with solar panels. Built-in MPPT controllers optimize solar charging efficiency.
