Goal Zero Yeti 300 vs Anker 555 PowerHouse
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 $400 less. Whether that gap is worth closing depends on what you need to run.
- Anker 555 PowerHouse holds 245% more energy (1024Wh vs 297Wh), so it runs the same load proportionally longer.
- Anker 555 PowerHouse has 900W more surge headroom (1500W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 300 is 16.2 lb lighter (13.7 lb vs 29.9 lb).
- Goal Zero Yeti 300 is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
Neither of these will start a sump pump or well pump — both surge below the ~3,400W those motors need. If home backup with pumps is your use case, look at higher-surge models instead of either of these.
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
A 1kWh unit whose 1,000W output and slow charging show its age — the newer, cheaper Anker C1000 beats it on nearly every axis.
Best for: Only worth it steeply discounted against the C1000.
Where it falls short:
- 1,500W surge is low
- 200W solar input and a slow 138-minute recharge
