What's in the box
[1] 0-80% in 43 minutes was measured in optimal conditions using the EcoFlow Smart Generator 4000 (Dual Fuel).
[2] Based on proper product usage, DELTA 3 Max Plus 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] 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.
[5] Feature requires preset activation via the EcoFlow App.
[6] To enable this feature, connect DELTA 3 Max Plus to the Smart Generator using the charging cable and enable the preset in the EcoFlow App. Communication is handled via Bluetooth or Wi-Fi.
[7] EcoFlow Solar Panels are sold separately.
[8] EcoFlow Alternator Charger Plus 1000 will be launched soon and is sold separately.
[9] Compared with car cigarette port charging.
[10] 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.
[11] 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.
[12] Multiple appliances' backup time based on ideal conditions; actual results may vary.
[13] Require connecting 1*DELTA 3 Max Plus + 2* DELTA 3 Max Plus Smart Extra Battery with EcoFlow Smart Extra Battery Expansion Adapter. The EcoFlow Extra Battery Expansion Adapter will be released soon.
[14] Require connecting 1*DELTA 3 Max Plus + 2* DELTA Pro 3 Smart Extra Battery with EcoFlow Smart Extra Battery Expansion Adapter. The EcoFlow Extra Battery Expansion Adapter will be released soon.
[15] EcoFlow Smart Generators are sold separately.
[16] Certain features in the EcoFlow app will be available soon. Please refer to the EcoFlow app for details on feature availability.
