Anker SOLIX F3800 vs Goal Zero Yeti 1000X
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 1000X costs $2800 less. Whether that gap is worth closing depends on what you need to run.
- Anker SOLIX F3800 holds 291% more energy (3840Wh vs 983Wh), so it runs the same load proportionally longer.
- Anker SOLIX F3800 has 6000W more surge headroom (9000W vs 3000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 1000X is 100.6 lb lighter (31.68 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 1000X. 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 older X-series 1kWh. Rugged and expandable, but its Li-ion cells and 2-year warranty look dated next to the LiFePO4 6th-gen Yeti 1000.
Best for: Only at a discount against the newer LiFePO4 Yeti 1000.
Where it falls short:
- NMC — ~500 cycles vs 4,000 for the new Yeti 1000
- 2-year warranty
