Anker SOLIX C300 vs Goal Zero Yeti 6000X
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 $5320 less. Whether that gap is worth closing depends on what you need to run.
- Goal Zero Yeti 6000X holds 2008% more energy (6071Wh vs 288Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 6000X has 2900W more surge headroom (3500W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker SOLIX C300 is 97.4 lb lighter (8.6 lb vs 106 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.
If you plan to cycle the battery daily, think twice about the Goal Zero Yeti 6000X. Its NMC cells are rated for 500 cycles against the LiFePO4 rival's longer life — over years of regular use that's the more expensive unit, whatever the sticker says.
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 huge-capacity home unit whose weakness is the same as its siblings: NMC cells with a low cycle count, at a flagship price.
Best for: Large-capacity backup for infrequent, deep-discharge use.
Where it falls short:
- NMC — ~500 cycles
- 2,000W output is low for the capacity
- 106 lb, 2-year warranty
