Side-by-side on the specs that decide it — surge, capacity, runtime and price.
Both models' specs verified against manufacturer listings · Last updated
The short answer
Jackery Explorer 1500 v2 costs $800 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 3 Ultra holds 100% more energy (3072Wh vs 1536Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Ultra has 3200W more surge headroom (7200W vs 4000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Jackery Explorer 1500 v2 is 46.3 lb lighter (37.5 lb vs 83.8 lb).
EcoFlow DELTA 3 Ultra
3kWh with 7200W surge at $1799 — this is whole-home territory at a mid-range price. The catch is the 800W solar input.
Best for: Grid-tied home backup where you recharge from the wall, not the sun.
Where it falls short:
- 800W solar input is low for 3kWh — slow off-grid refills
- 83.8 lb
Jackery Explorer 1500 v2
2000W output and 4000W surge at $999 makes this one of the better value picks for actual home backup, not just camping.
Best for: First-time home-backup buyers who need real surge on a budget.
Where it falls short:
- 1536Wh means about a day of fridge-plus-devices
- Not expandable
