Anker SOLIX C800 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
Anker SOLIX C800 costs $100 less. Whether that gap is worth closing depends on what you need to run.
- Anker SOLIX C800 holds 54% more energy (768Wh vs 499Wh), so it runs the same load proportionally longer.
- Anker SOLIX C800 has 600W more surge headroom (1600W vs 1000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 500 is 12.0 lb lighter (12.9 lb vs 24.9 lb).
- Goal Zero Yeti 500 is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
The Goal Zero Yeti 500 is poor value on paper: 0.71 Wh per dollar versus 1.28 for the Anker SOLIX C800. Only worth it if you specifically need its higher output or 240V capability — otherwise you're paying a large premium per watt-hour.
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
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
