Anker SOLIX C300 vs Goal Zero Yeti 200X
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 $120 less. Whether that gap is worth closing depends on what you need to run.
- Anker SOLIX C300 holds 54% more energy (288Wh vs 187Wh), so it runs the same load proportionally longer.
- Anker SOLIX C300 has 400W more surge headroom (600W vs 200W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 200X is 3.6 lb lighter (5 lb vs 8.6 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.
We'd skip the Goal Zero Yeti 200X in this matchup. It costs $120 more than the Anker SOLIX C300 while matching or trailing it on capacity, surge and cycle life — there's no spec here that justifies the premium.
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 tiny, well-built unit for USB devices and small electronics. The 120W AC inverter and Li-ion cells make it a charger, not a power station.
Best for: Ultralight trips charging phones, cameras and a small laptop.
Where it falls short:
- 120W AC output runs almost nothing with a plug
- ~500 cycles, 2-year warranty
