EcoFlow DELTA 2 Max 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 $1400 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 2 Max holds 753% more energy (2048Wh vs 240Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 2 Max has 4400W more surge headroom (4800W vs 400W) — that decides whether a fridge, pump or AC compressor will actually start.
- Jackery Explorer 240 is 43.4 lb lighter (6.6 lb vs 50 lb).
- EcoFlow DELTA 2 Max uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- EcoFlow DELTA 2 Max is rated for 3,000 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 surge sleeper. At 4800W it starts loads that stations twice its price can't — and most spec sheets bury that number behind the X-Boost figure.
Best for: Home backup where something with a compressor — fridge, freezer, window AC — has to start reliably.
Where it falls short:
- 50 lb is heavy for its capacity
- Marketing leads with the 3400W X-Boost number, which understates it
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
