EcoFlow RIVER 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 $100 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow RIVER 2 Max holds 113% more energy (512Wh vs 240Wh), so it runs the same load proportionally longer.
- EcoFlow RIVER 2 Max has 600W more surge headroom (1000W vs 400W) — that decides whether a fridge, pump or AC compressor will actually start.
- Jackery Explorer 240 is 6.6 lb lighter (6.6 lb vs 13.2 lb).
- EcoFlow RIVER 2 Max uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- EcoFlow RIVER 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.
Double the River 2's capacity and output for $100 more. The sweet spot of EcoFlow's small line for anyone eyeing the occasional small appliance.
Best for: Campers who want headroom over a pure device charger without the size of a 1kWh unit.
Where it falls short:
- Still not enough output for heaters or compressors
- 220W solar input is modest
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
