Anker SOLIX C300 vs Goal Zero Yeti 3000X
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 $3020 less. Whether that gap is worth closing depends on what you need to run.
- Goal Zero Yeti 3000X holds 953% more energy (3032Wh vs 288Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 3000X has 2900W more surge headroom (3500W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker SOLIX C300 is 61.1 lb lighter (8.6 lb vs 69.75 lb).
- Anker SOLIX C300 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Anker SOLIX C300 is rated for 3,000 cycles vs 500 — meaningful if you cycle it daily.
The Goal Zero Yeti 3000X is poor value on paper: 0.95 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.
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
A large-capacity unit held back by aging NMC cells. The capacity is real; the cycle life and charge speed are a generation behind.
Best for: Occasional-use backup where low cycle count won't bite.
Where it falls short:
- NMC — ~500 cycles against 4,000 for LiFePO4 rivals
- 69.75 lb and a 4-hour recharge
- 2-year warranty
