Capacity
Delta Pro: +1,552 Wh (+75.8%).
This comparison targets buyers choosing between two EcoFlow LFP stations for home backup or extended off-grid use. The Delta Pro delivers 3600W of running power and 3600 Wh of capacity, nearly doubling the DELTA 2 Max on both counts.
Its 7200W surge rating handles demanding startup loads from well pumps or large appliances, and it powered 47 out of 53 devices in our compatibility tests compared to 45 for the DELTA 2 Max. Solar input peaks at 1600W on the Delta Pro versus 1000W on the smaller unit, giving it a clear edge for faster panel-based recharging in whole-home scenarios.
The tradeoff is weight: at 99.2 lbs, the Delta Pro is roughly twice as heavy as the 50.7 lb DELTA 2 Max, making it far less practical for camping, tailgating, or any situation that requires regular transport.
