Differences EcoFlow River 2 Max vs Bluetti EB55
Below is a summary of the specifications:
Battery Capacity and Lifespan
The Bluetti EB55 has a slightly larger 537Wh battery, compared to the 512Wh capacity of the EcoFlow River 2 Max. While the difference is minimal, the Bluetti EB55 provides a slightly longer runtime for small appliances and devices.
Both models use LiFePO₄ (LFP) battery technology, which is known for long lifespans and safety. However, the EcoFlow River 2 Max has a longer cycle life of 3,000+ cycles to 80% capacity, while the Bluetti EB55 offers around 2,500 cycles. This means the River 2 Max will last longer before battery degradation becomes noticeable.
Winner: EcoFlow River 2 Max
While the Bluetti EB55 has a slightly larger battery, the River 2 Max wins with a longer lifespan.
Power Output and Device Compatibility
The Bluetti EB55 has an advantage in power output, offering 700W of continuous power with a 1,400W surge capacity. This allows it to handle more powerful devices such as small kitchen appliances, projectors, and power tools.
The EcoFlow River 2 Max, on the other hand, provides 500W of continuous power with a 1,000W surge capacity. While this is sufficient for charging laptops, smartphones, drones, and small appliances, it struggles with higher-powered devices that the Bluetti EB55 can handle.
Winner: Bluetti EB55
With higher continuous power (700W) and better surge capacity (1,400W), the Bluetti EB55 is the better choice for running more power-hungry appliances.
Charging Speed and Solar Input
Charging speed is a major factor for portable power stations, and this is where the EcoFlow River 2 Max takes the lead.
The River 2 Max features EcoFlow’s X-Stream fast charging, allowing it to charge from 0 to 80% in just 1 hour and 100% in 1.5 hours via AC power.
The Bluetti EB55, on the other hand, takes around 2.5 hours to reach 100% via AC charging, which is significantly slower.
For solar charging, the EcoFlow River 2 Max supports up to 220W input, while the Bluetti EB55 supports up to 200W. This gives the River 2 Max a slight advantage in renewable energy usage.
Winner: EcoFlow River 2 Max
The EcoFlow River 2 Max charges much faster via AC power and slightly faster via solar, making it a better choice for users who need quick recharging on the go.
Portability and Weight
Portability is a key factor for users who need lightweight power stations for camping, road trips, and outdoor events.
The EcoFlow River 2 Max weighs only 13.2 lbs (6 kg), making it significantly lighter than the Bluetti EB55, which weighs 16.5 lbs (7.5 kg). This makes the River 2 Max easier to carry and transport.
