EcoFlow RIVER 2 Max vs Jackery Explorer 240 v2
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 v2 costs $100 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow RIVER 2 Max holds 100% more energy (512Wh vs 256Wh), so it runs the same load proportionally longer.
- EcoFlow RIVER 2 Max has 400W more surge headroom (1000W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Jackery Explorer 240 v2 is 5.5 lb lighter (7.7 lb vs 13.2 lb).
- Jackery Explorer 240 v2 is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
Neither of these will start a sump pump or well pump — both surge below the ~3,400W those motors need. If home backup with pumps is your use case, look at higher-surge models instead of either of these.
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
Jackery's LiFePO4 entry point. A pocket-station rival to the EcoFlow River 2, trading a little output for Jackery's 4,000-cycle rating.
Best for: Weekend campers charging small devices on a budget.
Where it falls short:
- 300W output and one AC outlet
- 256Wh empties quickly under load
