Anker SOLIX F3000 vs Goal Zero Yeti PRO 4000
These are not the same class. One carries noticeably more battery than the other, so this is really a question about how much power you need rather than which brand builds better.
One is a size up
Goal Zero Yeti PRO 4000 holds around a third more battery — 3994Wh against 3,072Wh — and that is what decides how long either one lasts on the same load.
Anker SOLIX F3000 is 24 lb lighter, which at this size is the difference between carrying it and moving it.
Drawn from 7 specifications each maker publishes, of which 7 differ. We have not handled either machine — see our methodology.

What the extra battery buys you
Watt-hours are hard to picture, so here is each pack as runtime on the loads a machine this size is usually bought for. Both columns assume 85% inverter efficiency — the conservative end of what these are rated at — so read every figure as a floor.
| Load | Anker SOLIX F3000 | Goal Zero Yeti PRO 4000 |
|---|---|---|
| Full-size fridge (150W average) | 17 hours | 23 hours |
| Chest freezer (100W average) | 1.1 days | 1.4 days |
| Gas furnace blower (400W) | 6.5 hours | 8.5 hours |
| Sump pump, intermittent (300W average) | 8.7 hours | 11 hours |
| Space heater on low (750W) | 3.5 hours | 4.5 hours |
Published by only one of them
A figure missing from a spec sheet is not a zero — it is a number the maker chose not to state. These appear on one page and not the other, so they cannot be compared, only noted.
- Anker SOLIX F3000 — Operating temperature: 4°F-104°F / -20°C-40°C
- Goal Zero Yeti PRO 4000 — Warranty: 5 years
Where this comparison stops
Everything above is what the makers publish, not what either machine did in front of us. We own neither, so there is no noise measurement, no thermal behaviour under sustained load, and no view on how either holds up after two years. Makers also measure differently — cycle life at 80% capacity is not the same test as cycle life at 70% — so figures that look comparable sometimes are not. Treat this as a way to build a shortlist quickly, and read the caveats on our methodology page before you let a number decide.

Neither figure above is a price. These two move independently and often, and whichever is discounted this week is usually the answer when the specifications are as close as they are here.
