The differences that matter
Manufacturer-declared values. - Capacity and weight, 1 vs 2 kWh and 14.2 vs 23 kg → half the energy, but 8.8 kg less to lift. - Solar input, 1800 vs 1000 W → on the same panels the first refills its kilowatt-hour in a little over half an hour, the second needs about two hours for its 2 kWh. - Mains charging, 1.44 vs 2.4 kW → the second puts more energy back per minute from the wall. - Emergency switchover, 10 vs 20 ms → the first moves to battery with no interruption, the second with a brief pause.
Which one to choose
Choose DJI Power 1000 V2 if…
you move the unit often and want it to hold up equipment that cannot tolerate even a brief pause. At 1 kWh, though, a 2600 W load empties it in under 25 minutes, so plan on extra modules, which take the total to 11 kWh.
Choose EcoFlow DELTA 2 Max if…
you want more autonomy right out of the box and recharge often from the mains: 53 minutes to reach 80% against 37, but on a battery twice the size. You get four outlets instead of two, and you pay with 23 kg and an emergency output that has a brief pause.
