Quick answers
- Is the EcoFlow RIVER 2 better than the Goal Zero Yeti 300?
- Goal Zero Yeti 300 leads by 21 points overall.
- Which has more usable capacity, the EcoFlow RIVER 2 or Goal Zero Yeti 300?
- The Goal Zero Yeti 300, by 34 Wh — 218 Wh versus 252 Wh, a 16% advantage. At a 60 W load that is roughly 0.6 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 2 or Goal Zero Yeti 300?
- The Goal Zero Yeti 300: 300 W versus 350 W continuous. That gap matters only if a load sits between the two numbers — below 300 W both run it, above 350 W neither does. 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 2 and Goal Zero Yeti 300?
- On the same sourced load — a refrigerator (full-size) — the Goal Zero Yeti 300 runs longer: 4 hours against 3.5. 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 2 or Goal Zero Yeti 300?
- The EcoFlow RIVER 2, by 2.7 kg (3.5 kg versus 6.2 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 Goal Zero Yeti 300 for home backup; the EcoFlow RIVER 2 for camping & rv. They split, so the honest answer depends on which of those you are actually buying for.
