Anker SOLIX C300 vs Goal Zero Yeti 1500X
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 $1820 less. Whether that gap is worth closing depends on what you need to run.
- Goal Zero Yeti 1500X holds 426% more energy (1516Wh vs 288Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 1500X has 2900W more surge headroom (3500W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker SOLIX C300 is 37.0 lb lighter (8.6 lb vs 45.64 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 1500X is poor value on paper: 0.76 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
The previous-generation flagship. Its NMC battery is the catch — far fewer cycles than the LiFePO4 units now around it, including its own replacement.
Best for: Only at a steep discount against the newer LiFePO4 Yeti 1500.
Where it falls short:
- NMC chemistry — roughly 500 cycles vs 4,000 for the new 1500
- 180-minute recharge is slow
- Only a 2-year warranty
