At a Glance
This comparison targets buyers weighing raw capacity against portability and expandability. The Explorer 2000 v2 nearly doubles the DELTA 2's battery at 2042 Wh versus 1024 Wh, and its 2200W running output (4400W surge) powers heavier appliances that the 1800W DELTA 2 simply cannot handle.
That capacity edge shows in device coverage: the Explorer 2000 v2 passed 45 of 53 tested devices compared to 39 for the DELTA 2, earning a higher overall score of 88 to 73.5. Jackery's unit also includes a 20ms UPS transfer for basic home-backup scenarios, a feature EcoFlow omits here.
The tradeoff is real, though: at 39.5 lbs the Explorer 2000 v2 weighs 13 lbs more, it cannot expand with add-on batteries, and its 14.6-hour solar charge time on a 400W max input lags well behind the DELTA 2's 3.7 hours at 500W.
