Anker SOLIX C800 vs Goal Zero Yeti 300
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 300 costs $300 less. Whether that gap is worth closing depends on what you need to run.
- Anker SOLIX C800 holds 159% more energy (768Wh vs 297Wh), so it runs the same load proportionally longer.
- Anker SOLIX C800 has 1000W more surge headroom (1600W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 300 is 11.2 lb lighter (13.7 lb vs 24.9 lb).
- Goal Zero Yeti 300 is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
Neither of these will start a sump pump or well pump — both surge below the ~3,400W those motors need. If home backup with pumps is your use case, look at higher-surge models instead of either of these.
The C1000's smaller sibling. Same fast-charging DNA at a lower price, but the 768Wh capacity puts it firmly in weekend-trip territory.
Best for: Campers and van-lifers powering electronics, lights and a mini fridge — not home backup.
Where it falls short:
- 300W solar input is low — slow to top off off-grid
- 1600W surge rules out most motor-driven appliances
Goal Zero's compact entry: rugged and IPX4-rated, but you pay a premium over similar-capacity rivals for the drop-and-splash toughness.
Best for: Overlanders and job sites where the unit gets wet and knocked around.
Where it falls short:
- 350W output runs devices, not appliances
- $299 for 297Wh is pricey per watt-hour
