EcoFlow DELTA Pro 3 vs Jackery Explorer 300 Plus
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 300 Plus costs $3400 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Pro 3 holds 1322% more energy (4096Wh vs 288Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA Pro 3 has 7400W more surge headroom (8000W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Jackery Explorer 300 Plus is 104.7 lb lighter (8.27 lb vs 113 lb).
- EcoFlow DELTA Pro 3 is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
EcoFlow DELTA Pro 3
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
Jackery Explorer 300 Plus
A device charger, not a power station. At 8.27 lb and 288Wh it's for phones, laptops and a CPAP — nothing with a heating element or compressor.
Best for: CPAP users and travelers who need days of small-device power in a bag.
Where it falls short:
- 300W output rules out almost every appliance
- 288Wh is a single laptop-day of capacity
