EcoFlow DELTA 3 Ultra Plus vs Jackery Explorer 1500 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 1500 Ultra costs $800 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 3 Ultra Plus holds 100% more energy (3072Wh vs 1536Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Ultra Plus has 3600W more surge headroom (7200W vs 3600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Jackery Explorer 1500 Ultra is 59.0 lb lighter (26.5 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 1500 Ultra
The portability record-holder: 1536Wh at 26.5 lb, lighter than most 1kWh units. You pay $200 over the 1500 v2 for that weight saving.
Best for: Van lifers and overlanders where every pound is negotiated.
Where it falls short:
- 1800W output is lower than the cheaper 1500 v2's 2000W
- $1199 is a premium for weight alone
