EcoFlow RIVER 2 Max vs Jackery Explorer 1000
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
EcoFlow RIVER 2 Max costs $450 less. Whether that gap is worth closing depends on what you need to run.
- Jackery Explorer 1000 holds 96% more energy (1002Wh vs 512Wh), so it runs the same load proportionally longer.
- Jackery Explorer 1000 has 1000W more surge headroom (2000W vs 1000W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow RIVER 2 Max is 8.8 lb lighter (13.2 lb vs 22 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 1000. 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
The original Explorer 1000 — light and popular, but its Li-ion cells are rated for only ~500 cycles, a fraction of the LiFePO4 v2 that replaced it.
Best for: Occasional users who find it much cheaper than the v2.
Where it falls short:
- ~500 cycles vs 4,000 for the v2
- 1,000W output and 200W solar input
