[1] 0-80% in 75 minutes was measured in optimal conditions using X-Stream AC charging. Actual user experience may vary.
[2] Based on proper product usage, DELTA 3 Ultra Plus (3072Wh) 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] App features may vary by region. For detailed instructions, please contact customer support.
[4] EcoFlow Solar Panels are sold separately.
[5] EcoFlow 800W Alternator Charger is sold separately.
[6] Compared with car cigarette port charging. Data measured under ideal conditions; actual results may vary.
[7] 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.
[8] Noise levels measured at 1m under 25°C ambient: ≤25dB (600W) for charging/discharging.
[9] 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.
[10] 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.
