EcoFlow RIVER 2 Pro 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 2 Pro costs $1400 less. Whether that gap is worth closing depends on what you need to run.
- Goal Zero Yeti 1500X holds 97% more energy (1516Wh vs 768Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 1500X has 1900W more surge headroom (3500W vs 1600W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow RIVER 2 Pro is 28.6 lb lighter (17 lb vs 45.64 lb).
- EcoFlow RIVER 2 Pro uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- EcoFlow RIVER 2 Pro is rated for 3,000 cycles vs 500 — meaningful if you cycle it daily.
The Goal Zero Yeti 1500X is poor value on paper: 0.76 Wh per dollar versus 1.28 for the EcoFlow RIVER 2 Pro. Only worth it if you specifically need its higher output or 240V capability — otherwise you're paying a large premium per watt-hour.
The one you actually carry. At 17 lb it is light enough for one hand, yet unlike the true pocket units it has the 800W of output needed to run small appliances rather than just charge devices.
Best for: Backpackers, photographers and festival-goers who care about weight above all.
Where it falls short:
- 800W output limits you to electronics and small loads
- 220W solar input means slow off-grid top-ups
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
