Key Features Comparison: EcoFlow Delta Pro 3 vs Anker Solix f3800
Power/Performance – Winner: Anker Solix f3800
The EcoFlow Delta Pro 3 and Anker Solix F3800 are both powerhouses in terms of power and performance. The Anker Solix F3800 has slightly less battery capacity—3,840Wh compared to the 4,096Wh of the Delta Pro 3.On the other hand, the F3800 has significantly more power output. It can deliver up to 6,000W, with a 9,000W surge capacity. Additionally, the Anker Solix F3800 has two more AC outlets and one extra USB-C port compared to the EcoFlow Delta Pro 3. We would’ve liked to see two USB-A fast charge ports on the F3800 instead of the standard ones. Nevertheless, in terms of power and performance, the Anker Solix F3800 is the true heavyweight in this comparison.
Portability & Design – Winner: EcoFlow Delta Pro 3
Although power stations in this category are not meant to be highly portable, we’ll take a close look at their design and portability in case you plan to take one on a road trip with your RV.Both solar generators belong to the higher segment of portable power stations, and that is reflected in their design and build quality. The F3800 features a tower-style design, while the Delta Pro 3 has a suitcase-style build. We are not big fans of the tower design of the Anker Solix F3800. If you plan to use it stationary in your garage as an off-grid backup system, this may not be a big issue. However, if you plan to move it around and, for example, place it outside next to your RV on the grass, it can be a bit unstable. The four wheels also increase instability when placed on uneven surfaces.In contrast, the suitcase-style build of the Delta Pro 3 is more stable, easier to move around, and visually appealing.Therefore, in terms of portability and design, the clear winner is the EcoFlow Delta Pro 3.
Battery Life and Expandability – Winner: Anker Solix f3800
Both models come with an LFP battery, which is expected in high-end power stations. However, the Delta Pro 3 has a longer battery lifespan before reaching 80% of its capacity compared to the F3800.On the other hand, if you’re looking for a modular off-grid system capable of powering your entire house, the Anker Solix F3800 offers more potential. It is expandable up to 12,000W of power and 53,800Wh of capacity, whereas the Delta Pro 3 is expandable up to 48,000Wh.
Charging Time and Solar Compatibility – Winner: Anker Solix f3800
The charging times via AC will be quite the same for both units. But when we take a look at their solar generator capabilities things get interesting. EcoFlow is well know for its fast charging specs. However, the Anker Solix f3800 outperforms the Delta Pro 3 in terms of solar charging, with 2400W input vs 1600W respectively.
Price and Value for Money – Winner: Anker Solix f3800
Both of these power stations are high-end models from well-established solar generator brands. As a result, they come with a high price tag but also offer great value. Although the Anker Solix F3800 has a higher original retail price than the Delta Pro 3, Anker frequently offers discounts, making it very competitive and sometimes even better priced than the Delta Pro 3.
