Anker SOLIX F3800 vs Goal Zero Yeti 500
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 500 costs $3300 less. Whether that gap is worth closing depends on what you need to run.
- Anker SOLIX F3800 holds 670% more energy (3840Wh vs 499Wh), so it runs the same load proportionally longer.
- Anker SOLIX F3800 has 8000W more surge headroom (9000W vs 1000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 500 is 119.4 lb lighter (12.9 lb vs 132.3 lb).
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
A rugged, water-resistant unit for people who'll actually beat it up. You pay a premium over similar-capacity rivals for that durability.
Best for: Overlanders and job sites where the unit will get wet, dusty and knocked around.
Where it falls short:
- $699 for 499Wh is expensive per watt-hour
- Only a 2-year warranty vs 5 years from most rivals
- 120W solar input is very low
