Differences EcoFlow River 2 vs Bluetti AC2A
Below is a summary of the specifications:
Battery Capacity and Efficiency
Battery capacity plays a crucial role in determining how long a power station can sustain devices before needing a recharge.
The EcoFlow River 2 features a 256Wh LiFePO₄ battery, while the Bluetti AC2A has a slightly smaller 204Wh battery. This means the River 2 has about 25% more energy storage, making it more efficient for extended use when off-grid.
Both models use LiFePO₄ (LFP) battery chemistry, known for its long lifespan and safety. They each offer 3,000+ charge cycles before dropping to 80% capacity, ensuring years of reliable performance.
Winner: EcoFlow River 2
With a higher battery capacity, the River 2 provides longer runtimes and better efficiency for users who require more power.
Power Output and Device Compatibility
A power station’s wattage determines which appliances and devices it can run.
The EcoFlow River 2 and Bluetti AC2A both offer 300W continuous output with 600W surge capacity, making them suitable for charging phones, laptops, small fans, lights, and other low-power appliances.
Where the Bluetti AC2A has an edge is its USB-C port, which provides 100W power delivery (PD), compared to the 60W USB-C on the River 2. This makes the Bluetti a better choice for charging high-powered USB-C devices like MacBooks and gaming laptops.
Winner: Bluetti AC2A
With a higher 100W USB-C output, the AC2A is the better choice for users with high-powered USB-C devices.
Charging Speed and Solar Input
Fast recharging is critical for portable power stations, ensuring they can be quickly replenished between uses.
The EcoFlow River 2 boasts an ultra-fast AC charge time of just 1 hour (100%), using X-Stream fast charging technology. This makes it one of the fastest-charging portable power stations in its class.
The Bluetti AC2A takes slightly longer at 1.2 hours, though it compensates with a higher 200W solar input, allowing for faster off-grid solar charging compared to the 110W solar input on the River 2.
Winner: Tie
The River 2 excels in fast AC charging, while the AC2A is better for solar users due to its higher solar input.
Portability and Design
For portable power stations, size and weight matter—especially for users on the move.
Both the EcoFlow River 2 and Bluetti AC2A are lightweight, with the River 2 weighing 7.7 lbs (3.5 kg) and the AC2A at 7.9 lbs (3.6 kg). Their compact design makes them ideal for camping, RVs, and emergency kits.
Since their weights are nearly identical, portability is evenly matched between the two models.
Winner: Tie
Both are lightweight and compact, making them ideal for users who need portability.
Durability and Battery Lifespan
Durability is vital for long-term use, especially in outdoor and emergency situations.
Both the EcoFlow River 2 and Bluetti AC2A use LiFePO₄ batteries, which last significantly longer than traditional lithium-ion batteries. With a lifespan of 3,000+ charge cycles, these power stations offer years of use without significant battery degradation.
Winner: Tie
Both models provide exceptional durability with their LiFePO₄ battery technology.
