Anker SOLIX C800 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 C800 costs $1400 less. Whether that gap is worth closing depends on what you need to run.
- Goal Zero Yeti 1500X holds 97% more energy (1516Wh vs 768Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 1500X has 1900W more surge headroom (3500W vs 1600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker SOLIX C800 is 20.7 lb lighter (24.9 lb vs 45.64 lb).
- Anker SOLIX C800 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Anker SOLIX C800 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 1.28 for the Anker SOLIX C800. Only worth it if you specifically need its higher output or 240V capability — otherwise you're paying a large premium per watt-hour.
The C1000's smaller sibling. Same fast-charging DNA at a lower price, but the 768Wh capacity puts it firmly in weekend-trip territory.
Best for: Campers and van-lifers powering electronics, lights and a mini fridge — not home backup.
Where it falls short:
- 300W solar input is low — slow to top off off-grid
- 1600W surge rules out most motor-driven appliances
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
