EcoFlow DELTA 3 Ultra Plus vs Jackery Explorer 1000 Plus
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 Plus costs $1100 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 3 Ultra Plus holds 143% more energy (3072Wh vs 1264Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Ultra Plus has 3200W more surge headroom (7200W vs 4000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Jackery Explorer 1000 Plus is 53.5 lb lighter (32 lb vs 85.5 lb).
EcoFlow DELTA 3 Ultra Plus
The Ultra's solar problem solved: same everything, but 1600W of PV input instead of 800W. That doubles your off-grid refill speed for $200.
Best for: Off-grid cabins and van builds that actually recharge from panels.
Where it falls short:
- $1999 approaches DELTA Pro 3 pricing
- 85.5 lb
Jackery Explorer 1000 Plus
1264Wh with 4000W surge and expandability — a more capable unit than the 1000 v2 for $100 more, if you can accept the extra weight.
Best for: Buyers who want a 1kWh unit they can grow into a larger system.
Where it falls short:
- 32 lb vs the v2's 23.8 lb
- 2000W output is overkill for its capacity
