At a Glance
This comparison targets buyers choosing between two EcoFlow LFP stations that sit at very different points on the capacity spectrum. The Delta Pro delivers 3600W of running power and 3600 Wh of stored energy, roughly doubling the DELTA 3 Plus on both counts and tripling its battery capacity.
That gap shows up in device coverage: the Delta Pro powered 47 of 53 tested devices versus 42 for the DELTA 3 Plus, earning an overall score of 95 compared to 76.5. Surge handling follows the same pattern, with the Pro reaching 7200W against 3600W.
Solar input peaks at 1600W on the Pro versus 1000W on the smaller unit, though the DELTA 3 Plus refills far faster at 3.7 hours compared to 12.9 hours for the Pro. The tradeoff is weight: 27.6 lbs for the DELTA 3 Plus versus 99.2 lbs for the Delta Pro, a difference that reshapes how and where you can use each station.
