Jackery Explorer 1500 Ultra vs EcoFlow DELTA mini
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
EcoFlow DELTA mini costs $600 less. Whether that gap is worth closing depends on what you need to run.
- Jackery Explorer 1500 Ultra holds 74% more energy (1536Wh vs 882Wh), so it runs the same load proportionally longer.
- Jackery Explorer 1500 Ultra has 1500W more surge headroom (3600W vs 2100W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA mini is 2.9 lb lighter (23.6 lb vs 26.5 lb).
- Jackery Explorer 1500 Ultra uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Jackery Explorer 1500 Ultra is rated for 4,000 cycles vs 800 — meaningful if you cycle it daily.
If you plan to cycle the battery daily, think twice about the EcoFlow DELTA mini. Its NMC cells are rated for 800 cycles against the LiFePO4 rival's longer life — over years of regular use that's the more expensive unit, whatever the sticker says.
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
A compact NMC unit with a surprisingly strong 1,400W output for its size — but the 800-cycle battery means it won't age like the LiFePO4 field.
Best for: Buyers who want strong output in a light unit and won’t cycle it daily.
Where it falls short:
- NMC — ~800 cycles
- 2-year warranty, 300W solar input
