Quick answers

Is the EcoFlow RIVER 3 better than the Jackery Explorer 300 JE-300E LiFePO4?

Too close to call overall — choose by how and where you use it. No price tie-breaker today — choose based on fit and the sourced details.

Which has more usable capacity, the EcoFlow RIVER 3 or Jackery Explorer 300 JE-300E LiFePO4?

The Jackery Explorer 300 JE-300E LiFePO4, by 15 Wh — 208 Wh versus 223 Wh, a 7% advantage. At a 60 W load that is roughly 0.3 extra hours before the battery is empty.

Which has more AC output, the EcoFlow RIVER 3 or Jackery Explorer 300 JE-300E LiFePO4?

Neither — both are rated 300 W continuous, so any load one can run, the other can too. Surge headroom follows the same order: 600 W against 600 W, and surge is what decides whether a compressor or pump actually starts.

How does runtime compare between the EcoFlow RIVER 3 and Jackery Explorer 300 JE-300E LiFePO4?

On the same sourced load — a refrigerator (full-size) — the Jackery Explorer 300 JE-300E LiFePO4 runs longer: 3.5 hours against 3.3. These are planning estimates from each model's AC-delivered capacity, not stopwatch tests; real duty cycle and temperature move them.

Which is lighter, the EcoFlow RIVER 3 or Jackery Explorer 300 JE-300E LiFePO4?

They are effectively the same to carry — 3.5 kg against 3.4 kg. Neither is meaningfully easier to move, so portability should not decide this one.
