What we like

  • LFP battery rated for 3000+ cycles
  • EcoFlow app with Bluetooth and Wi-Fi
  • Clean 300W pure sine wave output

Could be better

  • Only 256Wh, not enough for overnight fridge use
  • 300W output limits what appliances you can run
  • No 30A or high-power DC outputs
  • Small display can be hard to read in sunlight

The EcoFlow River 2 is the entry point to EcoFlow's lineup, and it punches well above its price tag. At just 7.7 lbs and $249, it is the kind of power station you toss in a backpack without thinking twice.

Who Is the River 2 For?

The River 2 is purpose-built for light-duty use:

  • Day hikers and picnickers who want phone/laptop charging on the go
  • Remote workers at coffee shops or parks who need a few hours of laptop power
  • Festival and tailgate goers powering speakers, lights, and phone charging
  • Emergency kit essentials for keeping phones and lights running during short outages
  • Drone pilots who need a field-charging station between flights

Portability: This Is Its Superpower

At 7.7 lbs, the River 2 weighs less than a gallon of paint. You can carry it in one hand comfortably, and it fits inside most laptop bags. The compact dimensions (10 x 8.5 x 5.5 inches) mean it slides onto a shelf, into a car door pocket, or under a seat.

For anyone who has lugged a 30+ lb power station to a campsite, the River 2 feels almost unfairly convenient.

Charging Speed: 0 to 100% in 60 Minutes

EcoFlow's X-Stream charging technology works the same magic here as it does in the Delta series. Plug the River 2 into a wall outlet and it goes from empty to full in about 60 minutes. That is fast enough to charge it while you pack for a trip.

Solar charging accepts up to 110W, so a single 110W portable panel can recharge the River 2 in about 3 hours of direct sunlight. For a day trip with a panel, you can use it during the day and solar-top-off continuously.

Real-World Output

The 300W continuous output (600W surge) is enough for:

  • Laptop (65W): 3 full charges
  • Phone (20W): 10+ full charges
  • Drone battery (70W): 3 charges
  • LED lantern (10W): 20+ hours
  • Small fan (30W): 7+ hours

What it cannot do: run a mini-fridge, electric kettle, hair dryer, or any heating appliance. The 300W limit is real, and X-Boost mode only helps with devices that draw brief surges above the continuous rating.

Know Your Limits

The River 2 is not designed for heavy appliances. If you need to run a mini-fridge or cook, step up to the River 2 Max (512Wh, 500W) or the Delta 2 (1024Wh, 1800W).

Battery and Longevity

Like the Delta 2, the River 2 uses LFP chemistry. That means:

  • 3000+ charge cycles to 80% capacity
  • Safe in heat: LFP handles high temperatures better than NMC
  • Long shelf life: Retains charge well over months of storage

For a $249 device with a 3000-cycle battery, the cost per cycle works out to about 8 cents. That is exceptional value.

The EcoFlow App

You get the same excellent EcoFlow app as the higher-end models. Via Bluetooth or Wi-Fi you can:

  • Monitor real-time input and output
  • Set charge/discharge limits
  • Update firmware
  • View usage statistics

Having app control on a $249 power station is a genuine differentiator. Most competitors in this price range offer no smart features at all.

Build Quality

The River 2 has a clean, minimal design with a matte gray finish. The single carry handle is comfortable for one-handed use. The ports are well-spaced and clearly labeled.

The display is small but functional, showing remaining capacity, input/output wattage, and time to empty. In direct sunlight it can be hard to read, which is a minor annoyance for outdoor use.

Our Verdict

The EcoFlow River 2 earns a 4.2/5 rating. It is the best ultralight power station for people who need reliable, portable power for phones, laptops, and small devices. The 60-minute wall charge, LFP battery, and EcoFlow app make it feel like a premium product at a budget price.

The 256Wh capacity and 300W output mean it is not the right choice for running appliances or powering a campsite overnight. But for its intended use case, daily carry and light outdoor power, the River 2 is hard to beat.
