EcoFlow DELTA 3 Max 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 $600 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 3 Max holds 295% more energy (2048Wh vs 518Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Max has 3800W more surge headroom (4800W vs 1000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Jackery Explorer 500 is 41.8 lb lighter (13.3 lb vs 55.1 lb).
- EcoFlow DELTA 3 Max uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- EcoFlow DELTA 3 Max 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 value leader in the 2kWh class. Same 4800W surge as the DELTA 2 Max at $500 less, with 1000 more cycles.
Best for: Home backup buyers who want compressor-starting surge without paying flagship prices.
Where it falls short:
- 55 lb is a two-hand lift
- Only marginally lighter than heavier rivals
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
