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 1300 costs $1000 less. Whether that gap is worth closing depends on what you need to run.
- Goal Zero Yeti 1500X holds 20% more energy (1516Wh vs 1260Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 1500X has 200W more surge headroom (3500W vs 3300W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA 1300 is 14.7 lb lighter (30.9 lb vs 45.64 lb).
- EcoFlow DELTA 1300 is rated for 800 cycles vs 500 — meaningful if you cycle it daily.
Goal Zero Yeti 1500X
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
EcoFlow DELTA 1300
The original DELTA that put EcoFlow on the map. Fast-charging and high-surge for its day, but the NMC battery and lack of USB-C now show its age.
Best for: Bargain hunters who find it heavily discounted.
Where it falls short:
- NMC — ~800 cycles
- No USB-C PD
- 2-year warranty
