How we assign awards →No awards in this tier.
The differences that matter
- Capacity 2.048 vs 1.024 kWh → at the same load the DJI stays on twice as long, and it expands up to 22.528 kWh.
- Continuous output 3,000 vs 1,800 W → continuous loads between 1,800 and 3,000 W run only on the DJI.
- Solar input 1,800 vs 500 W → with panels the DJI recovers its energy during the day much faster.
- Weight 22 vs 12.1 kg → the DELTA 3 Classic can be carried in one hand, the DJI takes more effort.
Which one to choose
Choose DJI Power 2000 if…
you need more reserve and more power: 3,000 W continuous, expansion up to 22.528 kWh, 1,800 W of solar input, 45 minutes for 0–80%, a stated noise level of 29 dB and a 5-year warranty. The trade-off is 22 kg to move around.
Choose EcoFlow DELTA 3 Classic if…
you move it often and 1.024 kWh is enough: 12.1 kg, three mains outlets, two USB-C and one USB-A. You accept 1,800 W continuous, 500 W of solar input, 60 minutes for 0–80% and a 3-year warranty.
