Differences EcoFlow River 2 Max vs EcoFlow River 2 Pro
Below is a summary of the specifications:
Battery Capacity and Lifespan
Battery capacity is crucial for determining how long a power station can run essential devices before needing a recharge.
The EcoFlow River 2 Max has a 512Wh LiFePO₄ (LFP) battery, which offers superior safety, longevity, and durability compared to conventional lithium-ion batteries. With a lifespan exceeding 3,000 cycles, it retains 80% of its capacity even after years of regular use, making it one of the most long-lasting portable power stations in its class.
On the other hand, the Bluetti AC50B has a 500Wh lithium-ion (NCM) battery, which is slightly smaller than the River 2 Max. While still reliable, its 1,000-cycle lifespan means it won’t last as long as the LiFePO₄ alternative.
Winner: EcoFlow River 2 Max
With a larger battery capacity, LiFePO₄ technology, and extended lifespan, the River 2 Max is the better long-term investment.
Power Output and Device Compatibility
Power output determines which devices can be run efficiently using a portable power station.
The EcoFlow River 2 Max has a 500W continuous output with a 1,000W surge capacity, allowing it to power small appliances, laptops, CPAP machines, and even small refrigerators. It features four AC outlets, making it more versatile when powering multiple devices.
The Bluetti AC50B delivers 300W of continuous power and 600W surge capacity, which is better suited for charging small electronics like smartphones, tablets, and LED lights. It only has two AC outlets, limiting the number of devices it can power simultaneously.
Winner: EcoFlow River 2 Max
With higher power output, greater surge capacity, and more AC outlets, the River 2 Max is the better choice for users needing to power multiple or higher-wattage devices.
Charging Speed and Solar Input
A portable power station’s ability to recharge quickly is crucial, especially for off-grid users who rely on solar power.
The EcoFlow River 2 Max is one of the fastest-charging power stations on the market. It recharges from 0 to 80% in just 1 hour via AC power and reaches 100% in 1.3 hours. Additionally, it supports 220W of solar input, allowing it to fully charge in as little as 3 hours using solar panels.
The Bluetti AC50B, while still efficient, takes 3-4 hours to fully recharge via AC power and supports only 120W of solar input, which means solar recharging takes longer compared to the River 2 Max.
Winner: EcoFlow River 2 Max
With faster AC charging and higher solar input capacity, the River 2 Max offers superior recharging efficiency.
Portability and Weight
Portability is a key consideration for campers, travelers, and emergency preparedness.
The EcoFlow River 2 Max weighs 13.2 lbs (6 kg), while the Bluetti AC50B is slightly heavier at 13.6 lbs (6.2 kg). Both power stations are lightweight and compact, making them easy to carry for outdoor use.
Winner: Tie
Both models offer similar portability and weight, making them equally easy to transport.
Durability and Build Quality
Both power stations are built to withstand frequent use in outdoor conditions, but the EcoFlow River 2 Max’s LiFePO₄ battery gives it a distinct durability advantage. LFP batteries are more resistant to extreme temperatures, have a longer cycle life, and are inherently safer than lithium-ion NCM batteries, making the River 2 Max the better choice for long-term use.
Winner: EcoFlow River 2 Max
Thanks to its superior battery technology, the River 2 Max is a more durable and reliable option for heavy use.
