Comparison

1. 0-80% in 47 minutes was measured in optimal conditions using X-Stream AC charging.
2. Based on proper product usage, DELTA 3 Max Plus (2,048Wh) is estimated to have a lifespan of approximately 10 years, according to internal simulation test data. This information is for reference only; actual user experience may vary.
3. Compared with EcoFlow DELTA 2 Max.
4. The conclusion that multiple appliances can be powered simultaneously is based on internal testing. Actual performance may vary in real-world use.
5. Refers to the internal resistance of EF Full-Tab LFP Cells being 1.5mΩ, which is 25% lower than the 2mΩ internal resistance of the previous EF #C33 Battery Cell.
6. A 25% reduction in single-cell internal resistance. According to the heat generation formula Q = I²Rt, under the same current, a 25% reduction in resistance leads to a proportional 25% decrease in heat generation.
