EcoFlow RIVER 2 Max vs Jackery Explorer 500
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 $200 less. Whether that gap is worth closing depends on what you need to run.
- Jackery Explorer 500 holds 1% more energy (518Wh vs 512Wh), so it runs the same load proportionally longer.
- EcoFlow RIVER 2 Max is 0.1 lb lighter (13.2 lb vs 13.3 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 500. 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 long-running compact that's now firmly dated: one AC outlet, no USB-C, Li-ion cells and a very slow recharge. Only its ubiquity keeps it around.
Best for: Light, occasional device charging when found cheap.
Where it falls short:
- ~500 cycles
- One AC outlet, no USB-C
- 7.5-hour recharge
