The differences that matter
- Continuous (10 ms) vs emergency with a pause (30 ms) → only the first switches to battery without interrupting what it feeds.
- Maximum charge power 2.2 kW vs 2.875 kW → emptied, the first is full again in about an hour, the second in an hour and a quarter, but with nearly twice the energy to put back.
- Warranty 5 years vs 3 → the first has the longer cover.

Which one to choose
Choose DJI Power 2000 if…
the unit has to move often and you want to keep the door open to adding modules, up to 22 kWh; the 140 W USB-C port charges laptops and the declared noise level is 29 dB. The trade-off is the starting reserve: just over 2 kWh.
Choose EcoFlow DELTA Pro if…
you need more energy in a single unit, 3.6 kWh, with loads up to 3,600 W and starting surges up to 7,200 W. It weighs 45 kg, twice the other, but it has wheels and a handle.
