EcoFlow DELTA 3 Ultra Plus 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 $1850 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 3 Ultra Plus holds 3003% more energy (3072Wh vs 99Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Ultra Plus 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 83.4 lb lighter (2.13 lb vs 85.5 lb).
- EcoFlow DELTA 3 Ultra Plus is rated for 4,000 cycles vs 2,000 — meaningful if you cycle it daily.
EcoFlow DELTA 3 Ultra Plus
The Ultra's solar problem solved: same everything, but 1600W of PV input instead of 800W. That doubles your off-grid refill speed for $200.
Best for: Off-grid cabins and van builds that actually recharge from panels.
Where it falls short:
- $1999 approaches DELTA Pro 3 pricing
- 85.5 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
