Differences Anker 535 vs EcoFlow River 2 Pro
Below is a summary of the specifications:
Battery Capacity and Expandability
A portable power station’s battery capacity directly impacts how long it can power your devices.
The Anker 535 has a 512Wh battery, which is sufficient for small appliances, laptops, and essential devices but may struggle with extended power needs. It is not expandable, meaning users must rely solely on its internal battery capacity.
The EcoFlow River 2 Pro, on the other hand, features a larger 768Wh battery and offers expandability, allowing users to increase capacity with an additional battery pack. This makes it more versatile for longer off-grid use or backup power during outages.
Winner: EcoFlow River 2 Pro
With a larger base capacity and expandability, the River 2 Pro offers more flexibility for extended power needs.
Power Output and Device Compatibility
Power output determines which appliances a power station can handle.
The Anker 535 delivers 500W of continuous power and 1000W of surge capacity, making it suitable for small appliances, laptops, and basic electronics. However, it struggles with high-powered devices such as heaters, refrigerators, and power tools.
The EcoFlow River 2 Pro, by comparison, outputs 800W continuously with a 1600W surge capacity, meaning it can power larger appliances like coffee makers, mini-fridges, and some power tools. Additionally, EcoFlow’s X-Boost technology allows it to run devices up to 1600W, broadening its usability significantly.
Winner: EcoFlow River 2 Pro
With higher output power and surge capacity, the River 2 Pro can handle more demanding appliances.
Charging Speed and Solar Input
A fast-charging power station ensures minimal downtime between uses.
The Anker 535 supports AC charging up to 120W, taking approximately 2.5 hours for a full recharge. Its solar input is also limited to 120W, which means solar recharging takes longer, making it less ideal for off-grid solar users.
The EcoFlow River 2 Pro features AC charging up to 800W, achieving a 100% recharge in just 1.5 hours. With 220W of solar input, it also charges faster via solar panels, making it better suited for solar-dependent users.
Winner: EcoFlow River 2 Pro
With significantly faster charging and higher solar input, the River 2 Pro is the superior choice for users who need quick recharging.
Portability and Weight
Portability is crucial for outdoor enthusiasts and travelers, but it often comes at the cost of battery size and output power.
The Anker 535 is slightly lighter at 16.7 lbs (7.6 kg), making it easy to transport for camping and short trips.
The EcoFlow River 2 Pro, despite having a larger battery and higher output, is only 0.5 lbs heavier (17.2 lbs or 7.8 kg). This means it remains relatively portable while offering more power and features.
Winner: Tie
Both models are lightweight and easy to transport, making them equally portable.
Durability and Battery Lifespan
Both models use LiFePO₄ (LFP) battery technology, which ensures longer lifespan and improved safety compared to traditional lithium-ion batteries.
Each power station offers 3,000+ charge cycles, ensuring years of consistent performance before any significant battery degradation occurs.
Winner: Tie
Both Anker 535 and EcoFlow River 2 Pro have durable and long-lasting batteries.
