Anker SOLIX F3800 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
Goal Zero Yeti 1500X costs $2000 less. Whether that gap is worth closing depends on what you need to run.
- Anker SOLIX F3800 holds 153% more energy (3840Wh vs 1516Wh), so it runs the same load proportionally longer.
- Anker SOLIX F3800 has 5500W more surge headroom (9000W vs 3500W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 1500X is 86.7 lb lighter (45.64 lb vs 132.3 lb).
- Anker SOLIX F3800 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Anker SOLIX F3800 is rated for 4,000 cycles vs 500 — meaningful if you cycle it daily.
If you plan to cycle the battery daily, think twice about the Goal Zero Yeti 1500X. Its NMC cells are rated for 500 cycles against the LiFePO4 rival's longer life — over years of regular use that's the more expensive unit, whatever the sticker says.
This is where portable power stops being portable and starts replacing a standby generator. The 240V split-phase output is the headline feature.
Best for: Whole-home backup where you need 240V loads and can't run a gas generator.
Where it falls short:
- 132 lb — this is a wheeled appliance, not something you carry
- $3,999 puts it against real standby generators
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
