EcoFlow DELTA 3 Max Plus vs EcoFlow DELTA Pro
Technical comparison · Home backup
These are two power stations from the same family in different sizes: the choice depends on how much energy has to stay available at home and how often you will move it.

The differences that matter
- 2.048 versus 3.6 kWh → with a constant 1,000 W load, in theory about 2 hours versus about 3.5 hours, ignoring losses.
- 22.1 versus 45 kg → one is carried by hand, the other is moved but not lifted with ease.
- 1,000 versus 1,600 W of solar input → at full input both fill up in about 2 hours, in theory and in full sun: the difference is how much energy they store in that time.

Which one to choose
Choose EcoFlow DELTA 3 Max Plus if…
you use it as a backup supply, since it switches in 10 ms without interrupting the load, and you want a USB-C port that reaches 140 W. The trade-off: 3,000 W continuous and 6,000 W peak, so a bigger load stops it sooner.
Choose EcoFlow DELTA Pro if…
you have to power bigger loads: 3,600 W continuous and 7,200 W peak, with charging up to 2.875 kW. The trade-off: a brief interruption on switching to backup (30 ms) and a fastest USB-C port that stops at 100 W.
