Differences Anker SOLIX F3800 vs EcoFlow Delta Pro 3
Below is a summary of the specifications:
Battery Capacity and Expandability
Battery capacity is one of the most crucial aspects of a high-capacity power station. The Anker Solix F3800 comes with a 3,840Wh battery, while the EcoFlow Delta Pro 3 features a slightly larger 4,096Wh battery.
Both power stations offer expandability, meaning users can increase the capacity by adding extra battery modules. The EcoFlow Delta Pro 3 supports up to 48kWh when expanded, making it ideal for home backup and long-term off-grid applications. The Anker Solix F3800 also provides expandability, though its maximum extension is slightly lower (26.9kWh).
Winner: EcoFlow Delta Pro 3
With a larger base battery and greater expandability, the Delta Pro 3 takes the lead in this category.

Power Output and Device Compatibility
The continuous power output of a power station determines how many devices and appliances it can run simultaneously.
The Anker Solix F3800 delivers an impressive 6,000W continuous output with a surge capacity of 9,000W, making it the most powerful portable power station on the market. It can easily handle high-energy appliances like refrigerators, air conditioners, power tools, and electric stoves.
The EcoFlow Delta Pro 3, while still powerful, has a lower continuous output of 4,000W and a surge capacity of 8,000W. It can power most household appliances and off-grid devices, but it falls behind the Anker Solix F3800 when it comes to handling multiple high-energy loads simultaneously.
Winner: Anker Solix F3800
With higher continuous power (6,000W) and surge capacity (9,000W), the Anker Solix F3800 wins this category.
Solar Charging and Recharging Speed
For users who rely on solar energy, solar input capacity is a critical factor.
The Anker Solix F3800 offers an industry-leading 2,400W solar input, allowing it to charge quickly using solar panels. This makes it one of the fastest solar-charging portable power stations available.
The EcoFlow Delta Pro 3, while still excellent in this area, only supports 1,600W of solar input, meaning solar charging takes longer.
When it comes to AC charging, both models feature rapid recharging capabilities. The Anker Solix F3800 reaches 100% in just 2 hours, while the EcoFlow Delta Pro 3 takes around 2.3 hours.
Winner: Anker Solix F3800
With higher solar input (2,400W) and faster charging speeds, the Anker Solix F3800 is the superior choice for off-grid users.

Portability and Weight
While both models are large-capacity power stations, their weight differs significantly.
The Anker Solix F3800 weighs 132 lbs (60 kg), making it one of the heaviest portable power stations on the market. Its large battery and high output power contribute to its weight, but this could be a downside for users looking for easy transportability.
The EcoFlow Delta Pro 3 is slightly lighter at 115 lbs (52 kg), making it easier to move and transport. Both models come with wheels and handles for mobility, but the Delta Pro 3 has a slight advantage in terms of portability.
Winner: EcoFlow Delta Pro 3
For portability and ease of movement, the Delta Pro 3 is the better option.
Durability and Battery Lifespan
Both power stations use LiFePO₄ (LFP) battery technology, known for long lifespan, safety, and efficiency.
The Anker Solix F3800 provides 3,000+ charge cycles, while the EcoFlow Delta Pro 3 offers a longer lifespan of 6,500+ cycles. This means the Delta Pro 3 battery will last longer over time.
Winner: EcoFlow Delta Pro 3
With a higher cycle lifespan (6,500+ cycles), the Delta Pro 3 wins in durability.
