Both models' specs verified against manufacturer listings · Last updated
The short answer
EcoFlow DELTA 3 costs $550 less. Whether that gap is worth closing depends on what you need to run.
- Jackery Explorer 1500 Ultra holds 50% more energy (1536Wh vs 1024Wh), so it runs the same load proportionally longer.
- Jackery Explorer 1500 Ultra is 2.2 lb lighter (26.5 lb vs 28.7 lb).
EcoFlow DELTA 3
The 1kWh class got a serious upgrade here. 3600W surge at $649 beats the older DELTA 2 on every axis that matters.
Best for: Anyone about to buy a DELTA 2 — this is the same money for materially better specs.
Where it falls short:
- Still only 1024Wh
- Solar input unchanged at 500W
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
