DJI Power 2000 vs EcoFlow DELTA 3 Max
Technical comparison · Home backup
Same capacity (2.048 kWh, LFP cells) and four mains outlets on both: what changes is how much energy can go in and whether the unit can grow. The DJI expands and takes a large solar array, the EcoFlow stays a closed unit and is a little quieter. Values declared by the manufacturer.

The differences that matter
- Solar input 1800 W vs 500 W → in theory, in full sun and without losses, a little over 1 hour to fill the DJI and about 4 hours for the EcoFlow.
- Expandable to 22.528 kWh vs not expandable → the DJI becomes a system that grows, the EcoFlow stays at 2 kWh.
- Continuous output 3000 W vs 2400 W → 600 W more of loads you can connect together.
- Warranty 5 years vs 3 → at one cycle a day the cover lasts 1825 cycles vs 1095.
Which one to choose
Choose DJI Power 2000 if…
you want charging from a large solar array and a reserve you can multiply, with USB-C up to 140 W and a declared 0–80% in 45 minutes. You accept a declared noise of 29 dB against 25, and 1.7 kg more.
Choose EcoFlow DELTA 3 Max if…
the unit sits in a room where you live or work and the declared 25 dB matters; it charges at up to 2.3 kW and has a declared peak of 4800 W. You accept a 2 kWh unit with no expansion and slow solar charging.
