Capacity
Delta Pro Ultra X: +4,102 Wh (+200.9%).
This comparison targets buyers choosing between a high-capacity whole-home backup system and a more portable solar generator. The Delta Pro Ultra X delivers 12,000W of running power and 6,144 Wh of battery capacity, dwarfing the Explorer 2000 Plus at 3,000W and 2,042 Wh.
That gap carries over to device compatibility: the Ultra X powered all 53 tested devices, while the Explorer 2000 Plus handled 47 of 53. Surge capacity tells a similar story, with the Ultra X hitting 24,000W versus 6,000W for the Jackery unit.
Solar input on the EcoFlow tops out at 10,000W across up to 20 compatible panels, compared to 1,400W and 19 panels for the Explorer 2000 Plus. The tradeoff is physical: the Ultra X weighs 187.4 lbs, roughly triple the Explorer's 61.5 lbs, making it far less practical for travel or quick repositioning.
