EcoFlow DELTA Pro vs Goal Zero Yeti 1500
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
Goal Zero Yeti 1500 costs $1500 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Pro holds 139% more energy (3600Wh vs 1505Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA Pro has 3600W more surge headroom (7200W vs 3600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 1500 is 46.3 lb lighter (52.75 lb vs 99 lb).
- Goal Zero Yeti 1500 is rated for 4,000 cycles vs 3,500 — meaningful if you cycle it daily.
EcoFlow DELTA Pro
The previous-generation flagship, now mostly worth buying on discount. The Pro 3 beats it on nearly every axis.
Best for: Bargain hunters who find it steeply discounted against the Pro 3.
Where it falls short:
- 99 lb and 165-minute recharge — both beaten by the Pro 3
- Aging platform; expect it to be phased out
Goal Zero Yeti 1500
The new-for-2026 LiFePO4 Yeti 1500 — a big durability and cycle-life upgrade over the older 1500X it replaces.
Best for: Home backup buyers who want Goal Zero's build with modern battery chemistry.
Where it falls short:
- 52.75 lb — a two-hand lift
- 600W solar input is modest for the capacity
