Jackery Explorer 1000 v2 vs EcoFlow DELTA 3 Ultra
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 1000 v2 costs $1000 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 3 Ultra holds 187% more energy (3072Wh vs 1070Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Ultra has 4200W more surge headroom (7200W vs 3000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Jackery Explorer 1000 v2 is 60.0 lb lighter (23.8 lb vs 83.8 lb).
Jackery Explorer 1000 v2
The lightest 1kWh unit here at 23.8 lb, with a 3000W surge that punches above the Anker and EcoFlow units it competes with.
Best for: Campers who want 1kWh but care about carrying weight and need surge headroom.
Where it falls short:
- Only 3 AC outlets
- Not expandable — what you buy is what you get
- 400W solar input trails the Anker C1000's 600W
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
