Goal Zero Yeti 200X vs Growatt VITA 550
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
Goal Zero Yeti 200X costs $100 less. Whether that gap is worth closing depends on what you need to run.
- Growatt VITA 550 holds 188% more energy (538Wh vs 187Wh), so it runs the same load proportionally longer.
- Growatt VITA 550 has 1000W more surge headroom (1200W vs 200W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 200X is 12.6 lb lighter (5 lb vs 17.6 lb).
- Growatt VITA 550 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Growatt VITA 550 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 200X. 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.
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
A tidy half-kWh unit with fast charging and a 1,200W surge that lets it start small appliances a 600W rating wouldn't suggest.
Best for: Campers who want fast charging and a bit of surge headroom at half a kWh.
Where it falls short:
- 538Wh is weekend-scale
- 3-year warranty
