Quick answers
- Is the EcoFlow RIVER 3 Plus better than the Jackery Explorer 300 JE-300E LiFePO4?
- EcoFlow RIVER 3 Plus leads by 11 points overall.
- Which has more usable capacity, the EcoFlow RIVER 3 Plus or Jackery Explorer 300 JE-300E LiFePO4?
- Neither, in any way you would notice: 243 Wh against 248 Wh is a 2.1% gap, which is smaller than the swing you get from running the same load on a cold morning. Treat them as the same size and decide on output, weight, or today's price instead. Both figures are estimated AC-delivered energy, not the nameplate battery rating — the watt-hours that actually reach your devices.
- Which has more AC output, the EcoFlow RIVER 3 Plus or Jackery Explorer 300 JE-300E LiFePO4?
- The EcoFlow RIVER 3 Plus: 600 W versus 300 W continuous. That gap matters only if a load sits between the two numbers — below 300 W both run it, above 600 W neither does. Surge headroom follows the same order: 1,200 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 Plus and Jackery Explorer 300 JE-300E LiFePO4?
- They run within 2.1% of each other on the same load — about 3.9 hours each on a refrigerator (full-size). Runtime will not separate these two; the deciding factor is somewhere else.
- Which is lighter, the EcoFlow RIVER 3 Plus or Jackery Explorer 300 JE-300E LiFePO4?
- The Jackery Explorer 300 JE-300E LiFePO4, by 1.3 kg (3.4 kg versus 4.7 kg). Both weights are manufacturer figures for the bare unit; cables and a solar panel add to whatever you actually carry.
- Which model should I buy for my use case?
- On the sub-scores that describe each use case: the EcoFlow RIVER 3 Plus for home backup; the Jackery Explorer 300 JE-300E LiFePO4 for camping & rv. They split, so the honest answer depends on which of those you are actually buying for.
