EcoFlow DELTA 3 Max 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
EcoFlow DELTA 3 Max costs $600 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 3 Max holds 36% more energy (2048Wh vs 1505Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Max has 1200W more surge headroom (4800W vs 3600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 1500 is 2.4 lb lighter (52.75 lb vs 55.1 lb).
We'd skip the Goal Zero Yeti 1500 in this matchup. It costs $600 more than the EcoFlow DELTA 3 Max while matching or trailing it on capacity, surge and cycle life — there's no spec here that justifies the premium.
The value leader in the 2kWh class. Same 4800W surge as the DELTA 2 Max at $500 less, with 1000 more cycles.
Best for: Home backup buyers who want compressor-starting surge without paying flagship prices.
Where it falls short:
- 55 lb is a two-hand lift
- Only marginally lighter than heavier rivals
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
