The EcoFlow River 3 represents a significant evolution in compact portable power stations. With 245Wh of LiFePO4 battery capacity, 600W AC output, and EcoFlow’s signature fast charging, it aims to fill the gap between basic power banks and full-size power stations.

But in a crowded market of compact power solutions, does the River 3 justify its price point? We’ve spent four months testing this unit in real-world conditions — camping trips, outdoor work, emergency backup, and daily use scenarios. Here’s our detailed breakdown of what works, what doesn’t, and whether it deserves a place in your gear collection.

Bottom Line Up Front: The River 3 is an excellent compact power station that delivers on EcoFlow’s promises of fast charging and reliable performance. It’s perfect for specific use cases but may leave some users wanting more capacity.

Build Quality and Design

First Impressions

The River 3 feels substantially built despite its compact 7.8-pound weight. The housing combines EcoFlow’s signature gray and black color scheme with improved ergonomics — the handle is comfortable for extended carrying, and the overall footprint is compact enough to fit in most backpacks.

At 10.8” x 7.7” x 6.8”, it’s significantly smaller than previous River models while maintaining the build quality EcoFlow is known for. The unit feels dense and well-constructed, with no flex in the housing and tight panel gaps.

Port Layout and Accessibility

AC Outlets: 2x standard AC outlets (600W total)
DC Outputs: 1x 12V/8A car outlet, 1x 12V/3A barrel port
USB Outputs: 2x USB-A, 2x USB-C (up to 100W total)
Input: 1x DC input (AC/solar/car charging)

The port layout is clean and logical. The AC outlets are well-spaced and accommodate most plugs without blocking each other. USB ports are easily accessible, and the single DC input simplifies charging cables.

Our only minor complaint is that the 12V car outlet protrudes slightly, making it vulnerable to damage during transport. A recessed design would be more protective.

Display and Interface

The LCD display is bright and informative, showing battery percentage, input/output power, and estimated runtime. The information is clearly visible in various lighting conditions, including direct sunlight.

Physical controls are minimal and intuitive: main power button, AC outlet button, and DC outlet button. The interface responds quickly, and button presses are satisfyingly tactile.

Capacity and Real-World Performance

Advertised vs Actual Capacity

EcoFlow claims 245Wh of usable capacity, and our testing confirms this is accurate. Under moderate loads (100-300W), we consistently extracted 240-245Wh before the low battery cutoff. That’s refreshingly honest in a market where capacity inflation is common.

The LiFePO4 chemistry provides stable voltage throughout the discharge curve, maintaining consistent performance until the battery is nearly depleted.

Real-World Runtime Testing

We tested various common loads to provide realistic expectations:

Laptop Charging (65W MacBook Pro):
Runtime: 3.5-4 hours continuous
Cycles: 3-4 full laptop charges

LED Camping Setup:
Lantern (12W) + string lights (8W) + phone charging (10W)
Total: 30W

Inverter Performance

The 600W pure sine wave inverter performs well within its limits. We tested various loads up to 550W without issues. The 1200W surge rating handled starting loads for small appliances like blenders and coffee makers.

Power quality is excellent — we measured less than 3% total harmonic distortion under various loads, making it safe for sensitive electronics.

Load Testing Results:

• Coffee maker (400W): Ran successfully
• Small blender (500W peak): Handled startup surge well
• Hair dryer (1200W): Exceeded capacity, protection kicked in properly
• Power tools up to 500W: Performed well

Charging Performance

AC Charging Speed

Max Input: 100W
Full Charge Time: 2.5 hours
Efficiency: ~85%

This is where the River 3 shines. The 2.5-hour full charge time is impressive for any power station, let alone one at this price point. The charging curve is typical for LiFePO4 — fast to 80% (1.8 hours), then tapering to full.

The 100W AC input won’t overload household circuits or strain small inverters, making it suitable for charging from various AC sources.

Solar Charging

Max Input: 110W
Optimal Panel Configuration: 1x 110W or 2x 60W panels
Full Charge Time (ideal conditions): 2.8-3.5 hours

Solar charging performance is solid for the capacity class. The MPPT charge controller efficiently harvests available power and handles partial shading reasonably well.

Testing with EcoFlow 110W panel:

• Peak input: 95W (clear day)
• Average input: 65W (partly cloudy)
• Full charge time: 3.2 hours (optimal conditions)

Testing with 2x generic 60W panels (series):

• Peak input: 105W (clear day)
• Average input: 70W (mixed conditions)
• Full charge time: 3.8 hours (optimal conditions)

Car Charging

12V Input: 8A maximum
Charge Time: 4-5 hours

Car charging is reasonably fast for 12V input. The 8A draw is manageable for most vehicles without risking battery drain (with engine running).

We tested charging while driving and consistently achieved full recharge in 4-5 hours, making it practical for road trip use.

User Interface and App

Physical Interface

The LCD screen provides comprehensive information at a glance. Battery percentage (1% increments), real-time power flow, and runtime estimates are all clearly displayed. The interface is intuitive enough that most users won’t need the manual.
