- Power: 300 W, up to 600 W with X-Boost

Detailed overview
With the RIVER 2, EcoFlow delivers one of the most affordable and practical portable power stations in its range. This 256 Wh LiFePO4 (LFP) portable battery targets top-up needs: keeping your devices charged while camping, in a van, at the office or during a power cut, without hauling a bulky generator.
Its main asset comes down to a single figure: it recharges from 0 to 100% in just 60 minutes from a wall socket, thanks to X-Stream technology. That is far faster than most rivals, which are often stuck at 3 or 4 hours. You can also recharge in the car (12V/24V socket), over USB-C (60 W) or with a solar panel up to 110 W, for a full charge in around 3 hours in good sunlight.
On the connectivity side, the RIVER 2 covers the essentials:
- AC output: 300 W continuous (pure sine wave), up to 600 W in X-Boost mode
- 2 USB-A ports (12 W) and 1 bidirectional USB-C port (60 W)
- 1 car output at 12.6 V (100 W)
- Backup switchover (EPS) in under 30 ms
The LFP chemistry is the real long-term argument: over 3000 charge cycles before dropping below 80% capacity, close to ten years of regular use, versus roughly 500 cycles for older lithium-ion batteries. It is also more temperature stable and safer. EcoFlow backs it all with a 5-year warranty and TÜV Rheinland certification.
The limits are logical for this format: 256 Wh stays modest (ideal for smartphones, laptops, lighting and small appliances, but not for a heater or a fridge over time), and the capacity is not expandable. At just 3.5 kg and controllable through the EcoFlow app (Wi-Fi and Bluetooth), the RIVER 2 still ranks among the most versatile and best built portable power stations in its price class.
Comparison
Under the 300 euro mark, the EcoFlow RIVER 2 takes on the most sought-after compact portable power stations in its range, through searches like "EcoFlow RIVER 2 vs Bluetti EB3A" or "RIVER 2 vs Anker SOLIX C300". Here is how it stacks up against three direct alternatives: the Bluetti EB3A, known for its peak power, the Anker SOLIX C300, especially light, and the Jackery Explorer 300 Plus, its closest rival on capacity.
| Criterion | EcoFlow RIVER 2 | Bluetti EB3A | Anker SOLIX C300 | Jackery Explorer 300 Plus |
|---|---|---|---|---|
| Capacity | 256 Wh | 268 Wh | 288 Wh | 288 Wh |
| Continuous / peak power | 300 W / 600 W | 600 W / 1200 W | 300 W / 600 W | 300 W / 600 W |
| Battery chemistry | LFP (LiFePO4) | LFP (LiFePO4) | LFP (LiFePO4) | LFP (LiFePO4) |
| Mains recharge | 60 min (0-100%) | ≈ 1 h 10 (0-80% in 30 min) | ≈ 1 h | ≈ 2 h |
| Weight | 3.5 kg | ≈ 4.6 kg | ≈ 4.1 kg | ≈ 3.75 kg |
| Observed price | 299 € | ≈ 299 € (often 200-250 € on sale) | ≈ 299 € | ≈ 299 € |
In short, the EcoFlow RIVER 2 remains the most versatile option: it combines the fastest full recharge (60 min), the EcoFlow app and solar ecosystem and a featherweight design. The Bluetti EB3A wins on peak power (1200 W) and express partial charging, the Anker SOLIX C300 appeals mainly through its light weight, and the Jackery Explorer 300 Plus offers slightly more capacity but recharges more slowly. For nomadic use and light home backup, the RIVER 2 strikes the best overall balance.

Our tester's review: Christophe Delpuech
After several weeks with the RIVER 2, the first thing that stands out is how fast it recharges: plug it in while you pack your bag and it is full before you even leave. On a camping weekend it easily handled two smartphones, an LED lamp and a few laptop top-ups, with room to spare. Controlling it from the app is handy for capping the charge speed and protecting the battery, and the screen shows remaining runtime at a glance. We also liked charging on the move via the car socket, which tops it up during drives. Two honest downsides: the fan is audible when you draw a lot of power or during fast charging, and 256 Wh drains quickly as soon as you plug in a hungry device such as a kettle or a heater. Nothing to worry about at this price. For nomadic backup power or a light home safety net, it is an excellent entry point, reliable and long lasting thanks to its LFP battery.

From a wall socket it goes from 0 to 100% in just 60 minutes thanks to X-Stream technology. Expect around 3 hours with a 110 W solar panel in good sunlight conditions.
Yes for a small fridge or an electric cooler, but not for long: with 256 Wh, expect around 3 to 4 hours for a 60 W mini fridge. For extended use, look at a RIVER 2 Max or a DELTA instead.
Yes. Its EPS switch flips to battery in under 30 ms, fast enough for an internet box, a router or a light medical device such as a CPAP, which keep running with no visible interruption.
The RIVER 2 offers 256 Wh and 300 W; the RIVER 2 Max doubles the capacity to 512 Wh and rises to 500 W, for a weight of 6 kg versus 3.5 kg. The Max suits you if you need to power more devices or for longer.
