Capacity
DELTA Pro 3: +2,054 Wh (+100.6%).
This comparison targets buyers weighing raw power and expandability against portability and UPS functionality. The DELTA Pro 3 delivers 4000W of running power, nearly double the Explorer 2000 v2's 2200W, and its 4096 Wh battery holds roughly twice the capacity. It also powered 48 out of 53 devices in our compatibility testing, compared to 45 for the Jackery unit.
Solar input tells a similar story: the Pro 3 accepts up to 2600W from its 20 compatible panels, while the Explorer 2000 v2 caps at 400W. Expansion support on the EcoFlow side means you can scale storage over time, something the Jackery simply cannot do. The tradeoff is significant, though.
At 113.5 lbs, the Pro 3 is nearly three times heavier than the 39.5 lb Explorer 2000 v2, and only the Jackery offers a 20ms UPS transfer for keeping sensitive electronics online during outages.
