At a Glance

This comparison targets buyers choosing between a whole-home backup powerhouse and a portable solar generator built for lighter loads. The Delta Pro Ultra X delivers 12,000W of running power and 6,144 Wh of capacity, enough to handle 53 out of 53 devices tested.

The Explorer 2000 v2 covers 45 of the same 53 devices on 2,200W and 2,042 Wh, which still suits most standard appliances and electronics. Solar input tells a similar story: the Ultra X accepts up to 10,000W from as many as 20 compatible panels, while the Explorer 2000 v2 tops out at 400W.

On the flip side, the Jackery unit weighs just 39.5 lbs versus 187.4 lbs for the EcoFlow, and it offers UPS functionality with a 20ms switchover, a feature the Ultra X lacks. Battery longevity also favors the Explorer at 4,000 cycles compared to 3,200.
