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 costs $350 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Max 2000 holds 101% more energy (2016Wh vs 1002Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA Max 2000 has 1400W more surge headroom (3400W vs 2000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Jackery Explorer 1000 is 26.0 lb lighter (22 lb vs 48 lb).
- EcoFlow DELTA Max 2000 is rated for 800 cycles vs 500 — meaningful if you cycle it daily.
EcoFlow DELTA Max 2000
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
Jackery Explorer 1000
The original Explorer 1000 — light and popular, but its Li-ion cells are rated for only ~500 cycles, a fraction of the LiFePO4 v2 that replaced it.
Best for: Occasional users who find it much cheaper than the v2.
Where it falls short:
- ~500 cycles vs 4,000 for the v2
- 1,000W output and 200W solar input
