Goal Zero Yeti 500 vs Anker SOLIX C300
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 C300 costs $520 less. Whether that gap is worth closing depends on what you need to run.
- Goal Zero Yeti 500 holds 73% more energy (499Wh vs 288Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 500 has 400W more surge headroom (1000W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker SOLIX C300 is 4.3 lb lighter (8.6 lb vs 12.9 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 1.61 for the Anker SOLIX C300. Only worth it if you specifically need its higher output or 240V capability — otherwise you're paying a large premium per watt-hour.
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
Anker's smallest. 288Wh at $179 with three USB-C ports — aimed squarely at people charging modern devices, not running appliances.
Best for: Content creators and travelers with a bag full of USB-C gear.
Where it falls short:
- 300W output is device-only territory
- 100W solar input
