Bluetti AC500 vs Goal Zero Yeti 300
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 300 costs $1700 less. Whether that gap is worth closing depends on what you need to run.
- Bluetti AC500 holds 934% more energy (3072Wh vs 297Wh), so it runs the same load proportionally longer.
- Bluetti AC500 has 9400W more surge headroom (10000W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 300 is 52.4 lb lighter (13.7 lb vs 66.1 lb).
- Goal Zero Yeti 300 is rated for 4,000 cycles vs 3,500 — meaningful if you cycle it daily.
Bluetti AC500
A modular home-backup system, not a portable unit — the AC500 has no internal battery at all until you add B300K packs.
Best for: Serious home-backup builds where you're designing a system, not buying an appliance.
Where it falls short:
- Requires separate battery packs to function at all — budget accordingly
- Total system cost climbs fast
Goal Zero Yeti 300
Goal Zero's compact entry: rugged and IPX4-rated, but you pay a premium over similar-capacity rivals for the drop-and-splash toughness.
Best for: Overlanders and job sites where the unit gets wet and knocked around.
Where it falls short:
- 350W output runs devices, not appliances
- $299 for 297Wh is pricey per watt-hour
