At a Glance
This comparison targets buyers choosing between a heavy-duty home backup unit and a lightweight portable station. The DELTA Pro 3 delivers 4000W of running power with 4096 Wh of capacity, enough to handle 48 out of 53 devices in our compatibility testing. The Explorer 1000 v2 covers 33 of those same 53 devices, which suits lighter loads but leaves gaps for high-draw appliances.
Solar input tells a similar story: the Pro 3 accepts up to 2600W from up to 20 compatible panels, while the Explorer 1000 v2 tops out at 400W across 19 panels. Expandable battery support on the Pro 3 adds long-term flexibility the Jackery unit cannot match. The tradeoff is size.
At 23.8 lbs, the Explorer 1000 v2 is roughly one-fifth the weight of the 113.5 lb Pro 3, and it includes a 20ms UPS function the EcoFlow model lacks.
