Quick answers
- Is the EcoFlow RIVER 3 better than the Jackery Explorer 300 JE-300E LiFePO4?
- Jackery Explorer 300 JE-300E LiFePO4 takes capacity and output, EcoFlow RIVER 3 takes weight and noise — the decision is which of those you need, not overall quality. If neither is your constraint, the composite tiebreak goes to EcoFlow RIVER 3 by 1 point — a hair, not a mandate.
- Which has more usable capacity, the EcoFlow RIVER 3 or Jackery Explorer 300 JE-300E LiFePO4?
- The Jackery Explorer 300 JE-300E LiFePO4, by 40 Wh — 208 Wh versus 248 Wh, a 19% advantage. At a 60 W load that is roughly 0.7 extra hours before the battery is empty. Both figures are estimated AC-delivered energy, not the nameplate battery rating — the watt-hours that actually reach your devices, which is always less than the number on the box.
- 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: 3.9 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.
- Which model should I buy for my use case?
- On the sub-scores that describe each use case: the Jackery Explorer 300 JE-300E LiFePO4 for home backup, camping & rv. One model leads every use case we score here, which makes this an unusually clean choice.
