EcoFlow RIVER 3 Plus vs Goal Zero Yeti 1500X
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
EcoFlow RIVER 3 Plus costs $1670 less. Whether that gap is worth closing depends on what you need to run.
- Goal Zero Yeti 1500X holds 430% more energy (1516Wh vs 286Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 1500X has 2300W more surge headroom (3500W vs 1200W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow RIVER 3 Plus is 35.7 lb lighter (9.9 lb vs 45.64 lb).
- EcoFlow RIVER 3 Plus uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- EcoFlow RIVER 3 Plus 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 Goal Zero Yeti 1500X. 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.
Doubles the River 3's output for $90 more, and adds an expansion battery port. The better buy of the two unless weight is everything.
Best for: Campers who want one unit that covers devices plus the occasional small appliance.
Where it falls short:
- 286Wh alone is a single evening of real use
- 220W solar input is modest
The previous-generation flagship. Its NMC battery is the catch — far fewer cycles than the LiFePO4 units now around it, including its own replacement.
Best for: Only at a steep discount against the newer LiFePO4 Yeti 1500.
Where it falls short:
- NMC chemistry — roughly 500 cycles vs 4,000 for the new 1500
- 180-minute recharge is slow
- Only a 2-year warranty
