At a Glance
This comparison pairs two LFP-based portable power stations that sit at opposite ends of the capacity spectrum. The Delta Pro Ultra delivers 6,000W of running power and 6,144 Wh of stored energy, enough to cover 52 out of 53 devices in our compatibility testing.
The Explorer 1000 v2 handles 33 of those same 53 devices with 1,500W of output and 1,070 Wh of capacity. Solar charging further separates them: the Delta Pro Ultra accepts up to 5,600W of solar input and supports expandable battery modules, while the Explorer 1000 v2 caps at 400W and offers no expansion path.
That said, the Jackery unit weighs just 23.8 lbs compared to 182.1 lbs for the EcoFlow, includes a 20ms UPS function, and is rated for 4,000 charge cycles versus 3,200. Portability and longevity favor the Explorer 1000 v2; raw power and device coverage favor the Delta Pro Ultra.
