1. Based on proper product usage, DELTA 3 Classic 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.
2. Single-appliance runtime based on ideal conditions; actual results may vary.
3. All Charging speed data comes from EcoFlow labs and is for reference only. The actual data may vary slightly depending on the usage environment, device condition, software version, and other factors.
4. Feature requires preset activation via the EcoFlow App.
5. EcoFlow 500W Alternator Charger is sold separately.
6. 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.
7. 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.
8. Compared with the previous usage of EF #C33 Battery Cell.
9. Unless otherwise noted, all above data comes from EcoFlow labs and is for reference only. The actual data may vary slightly depending on the usage environment, device condition, software version, and other factors.
10. Noise levels measured at 0.5m under 25°C ambient: <30dB (600W) for charging/discharging.
