EcoFlow DELTA Pro 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 $3200 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Pro 3 holds 691% more energy (4096Wh vs 518Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA Pro 3 has 7000W more surge headroom (8000W vs 1000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Jackery Explorer 500 is 99.7 lb lighter (13.3 lb vs 113 lb).
- EcoFlow DELTA Pro 3 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- EcoFlow DELTA Pro 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 most complete large unit here. 4096Wh, 4000W, 8000W surge and 2600W of solar — it does everything the F3800 does with less weight.
Best for: Whole-home backup buyers who want maximum solar recharge speed.
Where it falls short:
- $3,699 is a serious investment
- Overkill unless you're backing up a whole home
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
