Goal Zero Yeti 1500X vs EcoFlow DELTA mini
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 DELTA mini costs $1400 less. Whether that gap is worth closing depends on what you need to run.
- Goal Zero Yeti 1500X holds 72% more energy (1516Wh vs 882Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 1500X has 1400W more surge headroom (3500W vs 2100W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA mini is 22.0 lb lighter (23.6 lb vs 45.64 lb).
- EcoFlow DELTA mini is rated for 800 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 1.47 for the EcoFlow DELTA mini. Only worth it if you specifically need its higher output or 240V capability — otherwise you're paying a large premium per watt-hour.
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
A compact NMC unit with a surprisingly strong 1,400W output for its size — but the 800-cycle battery means it won't age like the LiFePO4 field.
Best for: Buyers who want strong output in a light unit and won’t cycle it daily.
Where it falls short:
- NMC — ~800 cycles
- 2-year warranty, 300W solar input
