EcoFlow DELTA 3 Ultra Plus vs Jackery Explorer 240
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 240 costs $1800 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 3 Ultra Plus holds 1180% more energy (3072Wh vs 240Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Ultra Plus has 6800W more surge headroom (7200W vs 400W) — that decides whether a fridge, pump or AC compressor will actually start.
- Jackery Explorer 240 is 78.9 lb lighter (6.6 lb vs 85.5 lb).
- EcoFlow DELTA 3 Ultra Plus uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- EcoFlow DELTA 3 Ultra Plus 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 240. 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 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
A very old, very small unit still sold on price alone. The LiFePO4 Explorer 240 v2 beats it on cycles and charging for similar money.
Best for: Only if it’s markedly cheaper than the 240 v2.
Where it falls short:
- ~500 Li-ion cycles
- 200W output, no USB-C PD
