The differences that matter
- Continuous output: 2400 W vs 3600 W → the DELTA Pro runs more appliances together.
- Maximum solar input: 1000 W vs 1600 W → the DELTA Pro recharges faster from solar panels.
- Warranty: 5 years vs 3 years → the DELTA 2 Max carries a longer manufacturer coverage.
- Peak output: 4800 W vs 7200 W → the DELTA Pro absorbs higher startup load spikes.
Which one to choose
Choose EcoFlow DELTA 2 Max if…
Choose EcoFlow DELTA 2 Max if a smaller starting capacity (around 2 kWh) is enough and you'd rather expand it later to over 6 kWh, with a longer warranty and a lighter unit (23 kg). The trade-off is staying with smaller loads until you expand.
Choose EcoFlow DELTA Pro if…
Choose EcoFlow DELTA Pro if you need more capacity right away (3.6 kWh) to run several appliances together. The trade-off is a heavier unit (45 kg) and shorter warranty.
