EcoFlow RIVER 2 Pro 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
Jackery Explorer 500 costs $100 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow RIVER 2 Pro holds 48% more energy (768Wh vs 518Wh), so it runs the same load proportionally longer.
- EcoFlow RIVER 2 Pro has 600W more surge headroom (1600W vs 1000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Jackery Explorer 500 is 3.7 lb lighter (13.3 lb vs 17 lb).
- EcoFlow RIVER 2 Pro uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- EcoFlow RIVER 2 Pro 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 one you actually carry. At 17 lb it is light enough for one hand, yet unlike the true pocket units it has the 800W of output needed to run small appliances rather than just charge devices.
Best for: Backpackers, photographers and festival-goers who care about weight above all.
Where it falls short:
- 800W output limits you to electronics and small loads
- 220W solar input means slow off-grid top-ups
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
