Anker SOLIX F3800 vs Goal Zero Yeti 6000X
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
Anker SOLIX F3800 costs $1500 less. Whether that gap is worth closing depends on what you need to run.
- Goal Zero Yeti 6000X holds 58% more energy (6071Wh vs 3840Wh), 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 6000X is 26.3 lb lighter (106 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 6000X. 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
A huge-capacity home unit whose weakness is the same as its siblings: NMC cells with a low cycle count, at a flagship price.
Best for: Large-capacity backup for infrequent, deep-discharge use.
Where it falls short:
- NMC — ~500 cycles
- 2,000W output is low for the capacity
- 106 lb, 2-year warranty
