Capacity
DELTA Pro 3: +3,072 Wh (+300.0%).
This comparison targets buyers choosing between two EcoFlow LFP stations that share the same 4,000-cycle longevity but sit in very different weight and output classes. The DELTA Pro 3 delivers 4,000W of running power and 4,096 Wh of capacity, roughly four times the stored energy of the DELTA 3 Plus and its 1,024 Wh pack.
That gap shows in device coverage: the Pro 3 powered 48 of 53 tested devices compared to 42 for the DELTA 3 Plus, earning a score of 96 versus 76.5. Solar input ceiling on the Pro 3 reaches 2,600W, more than double the 1,000W limit on the smaller unit.
The tradeoff is portability. At 27.6 lbs, the DELTA 3 Plus is easy for one person to carry; the Pro 3 tips the scale at 113.5 lbs, making it a stationary or two-person-lift solution.
