Differences Bluetti AC70 vs EcoFlow River 2 Max
Below is a summary of the specifications:
Battery Capacity and Expandability
When it comes to battery capacity, the Bluetti AC70 offers 768Wh, significantly higher than the 512Wh capacity of the EcoFlow River 2 Max. This means the Bluetti AC70 can run devices for longer periods without requiring a recharge, making it ideal for extended outdoor adventures, emergency power backup, and high-energy-demand appliances.
The EcoFlow River 2 Max, while lower in capacity, is still sufficient for powering small to medium-sized appliances and is a lighter, more portable option.
Winner: Bluetti AC70
With a larger battery capacity, the Bluetti AC70 is the better option for users who need extended runtime.
Power Output and Device Compatibility
A power station’s output capacity determines the types of devices it can power. The Bluetti AC70 has a continuous output of 1,000W, with a surge capacity of 2,000W, allowing it to handle more power-hungry devices like electric grills, refrigerators, and even some power tools.
The EcoFlow River 2 Max is limited to 500W continuous power, with a 1,000W surge capacity, which makes it suitable for laptops, CPAP machines, and small kitchen appliances, but it struggles with high-wattage devices.
Winner: Bluetti AC70
With twice the power output, the AC70 is the better choice for users needing to run high-energy appliances.
Charging Speed and Solar Input
Both power stations feature fast charging capabilities, but EcoFlow’s advanced charging technology gives it an edge in AC charging efficiency. The EcoFlow River 2 Max charges from 0-80% in just 60 minutes via AC power, whereas the Bluetti AC70 achieves 80% in 45 minutes, making it one of the fastest-charging portable power stations.
For solar charging, the Bluetti AC70 supports up to 500W solar input, while the EcoFlow River 2 Max maxes out at 220W, meaning the AC70 can recharge significantly faster using solar panels.
Winner: Bluetti AC70
With higher solar input capacity and comparable AC charging speed, the Bluetti AC70 is better suited for off-grid and solar-dependent users.
Portability and Weight
Portability is a key factor for outdoor enthusiasts. The Bluetti AC70 weighs 22 lbs (10 kg), while the EcoFlow River 2 Max weighs only 13.2 lbs (6 kg). The lighter weight of the EcoFlow River 2 Max makes it easier to carry for camping trips, outdoor events, and travel.
Winner: EcoFlow River 2 Max
For users who need a lightweight, easily transportable power station, the River 2 Max is the better choice.
Durability and Battery Lifespan
Both power stations use LiFePO₄ (LFP) battery technology, which offers longer lifespan, better thermal stability, and enhanced safety compared to standard lithium-ion batteries. Each model has a lifespan of over 3,000 cycles before dropping to 80% capacity, ensuring years of reliable performance.
Winner: Tie
Both models offer high durability and long-lasting battery performance.
