The short answer

The Anker SOLIX F3800 Plus gives more of almost everything for $199 less: 3.84 kWh vs 4.1 kWh is the only spec where EcoFlow leads, while Anker has 6,000 W vs 4,000 W output, 3,200 W vs 2,600 W solar input, and expands to 26.9 kWh per unit vs 12.3 kWh. The EcoFlow is lighter (113.5 vs 136.7 lb), switches over faster (10 vs 20 ms), and quotes 4,000 cycles to 80% against Anker's 3,000+.

Choose the EcoFlow DELTA Pro 3 for slightly more base capacity, a higher cycle rating, lower weight and faster UPS switchover.

Choose the Anker SOLIX F3800 Plus for more power, more solar input and far more room to expand.

*Prices and specifications are from each manufacturer's US website, checked . Prices change often, sometimes daily during sales; the seller's page is the final word. Cycle ratings are the maker's own figures, measured to different end points, so treat them as rough guides.

How we compared

We compare only figures the manufacturers publish for their US models, and we link each one below. We have not lab-tested these units. Capacity is the rated battery capacity; usable AC energy is lower, typically by 10 to 20 percent, because of inverter losses. Cycle ratings are each maker's claim to its own end point.

Specifications and prices are copied from manufacturer websites on the date shown and change often. Confirm them with the seller before buying. See our disclaimer.
