EF ECOFLOW RIVER 2 240 Portable Power Station, 243Wh 300W

Power That Travels With You

The EcoFlow RIVER 2 240 is a compact, lightweight portable power station built around a 243Wh LiFePO4 battery and a 300W AC output — designed for people who need reliable power away from the grid without carrying extra weight. At 7.7 lb and small enough to slip into a daypack, it occupies a practical sweet spot between pocket-sized battery banks and bulkier power stations.

Why It Stands Out

Most power stations in this category use NMC lithium cells. The RIVER 2 240 uses LFP (LiFePO4) chemistry, which EcoFlow rates for over 3,000 charge cycles at 80% or more of original capacity. That's a meaningful long-term durability advantage — typical NMC-based competitors are rated for far fewer cycles before noticeable degradation.

Recharging is also unusually fast for this size: the AC wall input handles up to 360W, which means a full charge from empty in around 60 minutes in ideal conditions. For a sub-250Wh station, that's a genuine convenience advantage over slower-charging alternatives.

Key Specifications

• Dimensions: 9.6 × 8.5 × 5.7 inches

• Connectivity: Wi-Fi and Bluetooth (EcoFlow app)

Real-World Use Cases

The RIVER 2 240 handles everyday portable power needs without friction. Smartphones, laptops via the 60W USB-C port, tablets, camera gear, portable fans, small LED lights, and Wi-Fi routers all fall comfortably within its output range. It works well as a campsite companion for weekend trips, a desk battery for working through brief power outages, or a reliable power source during car travel or van life.

EcoFlow's X-Boost feature can extend compatibility to some devices rated up to 600W — but this depends on the specific appliance and its actual running wattage, so checking your device's real power draw before relying on it is advisable.

Who Should Consider It

The RIVER 2 240 is well matched for solo travelers, weekend campers, remote workers, and anyone who needs a compact backup power solution for essentials. It's equally useful in a go-bag for emergencies or in a car trunk for unplanned situations.

Things to Know Before Buying

• Output ceiling matters: The 300W continuous AC output is the primary practical constraint. Heaters, kettles, hair dryers, microwaves, and most power tools require significantly more wattage and are not suitable loads for this unit.

• Capacity for the use case: 243Wh is meaningful for phones, laptops, and small electronics, but high-drain appliances will deplete it quickly even if they fall within the wattage limit.

• Solar charging: The 110W solar input cap requires a compatible panel sold separately. EcoFlow makes compatible panels, and third-party options with the right connector and specs also work.

• Model naming: Some retailers list this simply as "RIVER 2" — the 240 designation specifies the 243Wh capacity variant.

• Operating temperature: Discharge range is 14°F to 113°F; charging requires temperatures above 32°F.

Final Thoughts

For what it is — a genuinely portable, fast-charging, long-lived power station focused on essentials — the EcoFlow RIVER 2 240 delivers. The LFP battery chemistry and rapid AC recharge set it apart from comparably priced alternatives. If your power needs stay within the 300W output range and 243Wh capacity, it's a practical, well-engineered solution worth serious consideration.

Frequently Asked Questions

Can the EcoFlow RIVER 2 240 charge a laptop? Yes. The 60W USB-C port will charge most laptops and ultrabooks at or near their full charging speed. Larger workstation-class laptops with 100W+ chargers will charge at a reduced rate.

How long does a full charge take? Using AC wall charging at up to 360W, a full charge from empty takes approximately one hour under ideal conditions.

Is it safe to leave plugged in? EcoFlow includes battery management protections in the RIVER 2 240. The unit is designed to handle common charging scenarios, though continuous full-charge storage over extended periods is generally not recommended for any lithium battery.

Can it power a mini fridge? It depends on the fridge's running wattage. A compact 12V travel cooler or small car fridge under 60W can work well. Standard mini fridges often exceed 100W running draw, which is possible but will deplete the 243Wh capacity relatively quickly.

What is X-Boost? X-Boost is EcoFlow's technology that allows the RIVER 2 240 to intelligently power some devices rated up to 600W by regulating power delivery. It works for many small appliances, but results vary by device and actual power consumption.
