EcoFlow DELTA 3 Ultra vs Jackery Explorer 100 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 100 Plus costs $1650 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 3 Ultra holds 3003% more energy (3072Wh vs 99Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Ultra has 6944W more surge headroom (7200W vs 256W) — that decides whether a fridge, pump or AC compressor will actually start.
- Jackery Explorer 100 Plus is 81.7 lb lighter (2.13 lb vs 83.8 lb).
- EcoFlow DELTA 3 Ultra is rated for 4,000 cycles vs 2,000 — meaningful if you cycle it daily.
EcoFlow DELTA 3 Ultra
3kWh with 7200W surge at $1799 — this is whole-home territory at a mid-range price. The catch is the 800W solar input.
Best for: Grid-tied home backup where you recharge from the wall, not the sun.
Where it falls short:
- 800W solar input is low for 3kWh — slow off-grid refills
- 83.8 lb
Jackery Explorer 100 Plus
At 2.1 lb this is a laptop battery with an AC outlet. Genuinely pocketable, genuinely limited.
Best for: Air travelers and photographers topping up cameras and laptops.
Where it falls short:
- 128W output runs almost nothing with a motor or heater
- 99Wh is roughly one laptop charge
