EcoFlow DELTA 3 vs Jackery Explorer 500
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 500 costs $150 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 3 holds 98% more energy (1024Wh vs 518Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 has 2600W more surge headroom (3600W vs 1000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Jackery Explorer 500 is 15.4 lb lighter (13.3 lb vs 28.7 lb).
- EcoFlow DELTA 3 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- EcoFlow DELTA 3 is rated for 4,000 cycles vs 500 — meaningful if you cycle it daily.
If you plan to cycle the battery daily, think twice about the Jackery Explorer 500. Its NMC cells are rated for 500 cycles against the LiFePO4 rival's longer life — over years of regular use that's the more expensive unit, whatever the sticker says.
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
A long-running compact that's now firmly dated: one AC outlet, no USB-C, Li-ion cells and a very slow recharge. Only its ubiquity keeps it around.
Best for: Light, occasional device charging when found cheap.
Where it falls short:
- ~500 cycles
- One AC outlet, no USB-C
- 7.5-hour recharge
