EcoFlow DELTA 2 vs EcoFlow DELTA Pro
Technical comparison · Home backup
Same maker, same LFP chemistry, four mains sockets and the same short-pause switchover (EPS, 30 ms), but different sizes: about 1 kWh against 3.6 kWh. What decides it is how much load you want to run and how much weight you are willing to move (manufacturer-declared values).

The differences that matter
- Capacity and weight, 1.024 kWh and 12 kg vs 3.6 kWh and 45 kg → about three and a half times the energy for nearly four times the weight.
- Continuous and peak output, 1,800 and 2,700 W vs 3,600 and 7,200 W → the DELTA Pro carries twice the continuous load and more than twice the peak.
- Solar input and mains charging, 500 W and 1.2 kW vs 1,600 W and 2.875 kW → the DELTA Pro refills much faster, from panels and from the mains.
- Warranty, 5 vs 3 years → on both, the warranty ends before the declared cycles (3,000 and 3,500), so it sets how long you are covered.
Which one to choose
Choose EcoFlow DELTA 2 if…
you move it yourself, from room to room or out to the car, and run medium loads for a few hours. You accept that a heavy load drains it quickly and that there is no headroom for very demanding appliances; in return the warranty is longer.
Choose EcoFlow DELTA Pro if…
you leave it in a fixed spot at home and move it on its wheels and handle (declared by the maker) only when needed, running several appliances at once or loads with high peaks. The price is weight, which makes placement a one-time decision, and a shorter warranty.
