What's In The Box
- Based on proper product usage, DELTA 3 Classic (1024Wh) 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.
- 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.
- Features require preset activation via the EcoFlow App.
- EcoFlow Smart Generators are sold separately.
- EcoFlow 500W Alternator Charger is sold separately.
- Single-appliance runtime based on ideal conditions; actual results may vary.
- 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.
- 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.
- Unless otherwise noted, all images, videos, and screen display contents about the product itself on this page are for reference only. Actual product effects (including but not limited to appearance, color, and size) and screen display contents (including but not limited to backgrounds, UI, and illustrations) may vary.
