EcoFlow RIVER 2 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 costs $300 less. Whether that gap is worth closing depends on what you need to run.
- Jackery Explorer 500 holds 102% more energy (518Wh vs 256Wh), so it runs the same load proportionally longer.
- Jackery Explorer 500 has 400W more surge headroom (1000W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow RIVER 2 is 5.6 lb lighter (7.7 lb vs 13.3 lb).
- EcoFlow RIVER 2 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- EcoFlow RIVER 2 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.
The cheapest way into LiFePO4. 256Wh is a device charger, but at under $200 with a 60-minute recharge it's hard to argue with.
Best for: Budget campers who just need to keep phones, cameras and a laptop alive.
Where it falls short:
- 300W output runs devices only
- 256Wh is a single evening of real use
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
