Power on the Go: The EcoFlow RIVER 3 in ClearBuy's Test
Imagine you're at a multi-day festival, far from any outlet, and your smartphone is at 5% battery. Or your drone needs to fly for that perfect sunset, but the battery is dead. For such scenarios, the EcoFlow RIVER 3 promises a compact and powerful solution. We have extensively tested this new power station to find out if it can deliver on these promises in everyday use.First Impressions & Scope of Delivery
Upon unboxing the EcoFlow RIVER 3, one thing immediately stands out: this device is designed for mobile use. Compact and robust, it feels good in your hand. The scope of delivery includes the power station itself, an AC charging cable, a car charging cable, and a quick start guide. It's a positive note that EcoFlow includes all essential cables, so you can get started right away without having to buy additional accessories. The EcoFlow RIVER 3 does not require an external power supply. The charging cable plugs directly into the power station, simplifying handling and reducing pack size.Always keep the included charging cables (AC and car charger) with your EcoFlow RIVER 3. This ensures you can recharge it anytime, anywhere, without needing to purchase additional accessories.
Design & Build Quality
The EcoFlow RIVER 3 presents itself with a modern, functional design. The housing is made of high-quality plastic and is predominantly in dark gray tones. An integrated, ergonomically shaped carrying handle allows for comfortable transport. All ports are easily accessible on the front and sides and feature clean workmanship. The buttons have a pleasant pressure point, and the display is easy to read even in direct sunlight. Here, you notice that EcoFlow prioritizes a practical design that meets the demands of mobile use.Technical Data & Capacity
With a capacity of 245 Wh, the EcoFlow RIVER 3 is one of the smaller power stations on the market, but it aims to impress precisely with its compactness. This capacity is sufficient to fully charge an average smartphone (approx. 3,000 mAh) about 20-25 times or power a laptop (approx. a 60 Wh battery) about 4 times. A small cooler (40 W) could be operated for approximately 6 hours. The output power of 300 W (with a peak of up to 600 W for a short time) allows the operation of most common small appliances. The 300 W output and 600 W peak power are sufficient for most electronic devices in the home or while camping, with the exception of very power-hungry devices like space heaters or kettles. Always check the power consumption of your devices before connecting them to a power station.The 245 Wh capacity of the RIVER 3 is designed for portability and quick recharges. While higher capacity power stations exist, they are often larger and heavier, making the RIVER 3 ideal for users prioritizing compact size and rapid charging.
Ports & Outputs
The connectivity of the EcoFlow RIVER 3 is impressive and covers most common needs. On the front, you'll find:- 2 x AC outlets (NEMA 5-15 plug): For devices with a main plug, up to 300 W continuous power.
- 2 x USB-A outputs: Ideal for charging smartphones, tablets, and other small devices.
- 1 x USB-C output (Power Delivery): Particularly useful for modern laptops or fast charging functions.
- 1 x 12V car socket: Perfect for coolers or other 12V devices.
- 1 x DC5521 output: For specific DC devices that use such a connection.
Charging Options & Speed
A crucial feature of many power stations is charging speed, and here the EcoFlow RIVER 3 particularly stands out. The manufacturer's specification of 56 minutes for a full charge was actually achievable in our test when the power station was charged via a wall outlet. This is an absolute top value in its class and allows for spontaneous use even with short-term energy needs. Further charging options include:- Car charging (12V/24V): Ideal for longer journeys or for on-the-go replenishment.
- Solar panel charging (optional): With an optionally available solar panel, the RIVER 3 can also be charged autonomously with solar energy.
Practical Test
In the test, we used the EcoFlow RIVER 3 under various conditions: Camping Trip: Here, it served as the central power source for charging smartphones, a camping lamp, and operating a small cooler. The capacity was easily sufficient for a weekend, given conscious power management. The integrated LED lighting on the back proved to be a practical feature. Outdoor Photoshoot: A drone and a camera battery charger were able to be recharged multiple times. Power Outage at Home: During a short power outage, the RIVER 3 effortlessly powered a laptop, the Wi-Fi router, and a few lamps, allowing work to continue and communication to be maintained. The display consistently provides clear information about the current charge level, input, and output power. The fans operate audibly under load but are not bothersome.Smart Features & App
The EcoFlow RIVER 3 can be controlled via the EcoFlow App, which is available for iOS and Android. The Bluetooth connection works smoothly, and the app offers an intuitive user interface. Various settings can be made via the app, including:- Monitoring charge level and power output
- Turning individual outputs on and off
- Adjusting AC charging power: This is particularly practical if you want to charge the power station from a less powerful outlet or minimize fan noise.
- Firmware updates: Ensure the power station is always up-to-date.
While the EcoFlow app is a great feature, rely on the physical display for critical power level checks during demanding situations. App connectivity, though generally stable, can be affected by environmental factors.
Comparison with the Competition
In direct comparison with similar power stations in its price and performance class (e.g., Jackery Explorer 240 or Anker PowerHouse 204 Wh), the EcoFlow RIVER 3 particularly scores with its extremely fast charging time. While competitor products often require several hours for a full charge, the RIVER 3 is unbeatable with under one hour. The higher peak power of 600 W and the more comprehensive range of ports (especially the USB-C PD port) are also advantages. The integration into the EcoFlow App for remote control and monitoring represents another step forward. In return, the capacity of 245 Wh is appropriate for the segment but not leading. Here, each user must weigh whether fast charging time and connectivity are more important than a few extra watt-hours of capacity. However, for the asking price, you get an overall package that stands out from the crowd in many respects.FAQ
