EcoFlow DELTA 3 Max Plus 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 DELTA 3 Max Plus costs $700 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 3 Max Plus holds 35% more energy (2048Wh vs 1516Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Max Plus has 2500W more surge headroom (6000W vs 3500W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 1500X is 11.7 lb lighter (45.64 lb vs 57.3 lb).
- EcoFlow DELTA 3 Max Plus uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- EcoFlow DELTA 3 Max Plus is rated for 4,000 cycles vs 500 — meaningful if you cycle it daily.
We'd skip the Goal Zero Yeti 1500X in this matchup. It costs $700 more than the EcoFlow DELTA 3 Max Plus while matching or trailing it on capacity, surge and cycle life — there's no spec here that justifies the premium.
Adds 600W of continuous output and doubles surge headroom over the standard Max, for $200. Worth it only if you're running heavy loads.
Best for: Workshops and job sites where tool startup surge is the constraint.
Where it falls short:
- $200 premium is wasted if your loads are under 2400W
- 57 lb
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
