Capacity
Delta Pro Ultra: +3,120 Wh (+103.2%).
This comparison targets buyers weighing raw power and expandability against portability and simplicity. The Delta Pro Ultra delivers 6,000W of running power and 6,144 Wh of capacity, doubling the Explorer 3000 Pro's 3,000W output and 3,024 Wh reserve. That gap shows up in device coverage: the EcoFlow unit powered 52 of 53 tested devices, while the Jackery handled 47 of 53.
Solar charging reinforces the divide, with the Delta Pro Ultra accepting up to 5,600W of panel input versus 1,400W for the Explorer 3000 Pro. LFP chemistry and 3,200 cycle life give the EcoFlow model a longer service window than the Jackery's 2,000-cycle NMC cells. The tradeoff is weight.
At 182.1 lbs, the Delta Pro Ultra is nearly three times heavier than the 63.9 lb Explorer 3000 Pro, making the Jackery far easier to load into a vehicle or reposition at a campsite.
