Jackery Explorer 1500 Ultra vs EcoFlow DELTA Max 2000
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 Max 2000 costs $100 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Max 2000 holds 31% more energy (2016Wh vs 1536Wh), so it runs the same load proportionally longer.
- Jackery Explorer 1500 Ultra has 200W more surge headroom (3600W vs 3400W) — that decides whether a fridge, pump or AC compressor will actually start.
- Jackery Explorer 1500 Ultra is 21.5 lb lighter (26.5 lb vs 48 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 Max 2000. 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
The previous-generation 2kWh EcoFlow. Still capable and expandable, but its NMC cells and 800-cycle rating are a real step below the LiFePO4 DELTA 3 that replaced it.
Best for: Only at a steep discount against the DELTA 3 Max.
Where it falls short:
- NMC — roughly 800 cycles vs 4,000 for the DELTA 3 Max
- 2-year warranty
