Goal Zero Yeti 3000X vs Anker 535 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
Anker 535 PowerHouse costs $2770 less. Whether that gap is worth closing depends on what you need to run.
- Goal Zero Yeti 3000X holds 492% more energy (3032Wh vs 512Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 3000X has 2750W more surge headroom (3500W vs 750W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker 535 PowerHouse is 53.0 lb lighter (16.7 lb vs 69.75 lb).
- Anker 535 PowerHouse uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Anker 535 PowerHouse 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 3000X. 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 large-capacity unit held back by aging NMC cells. The capacity is real; the cycle life and charge speed are a generation behind.
Best for: Occasional-use backup where low cycle count won't bite.
Where it falls short:
- NMC — ~500 cycles against 4,000 for LiFePO4 rivals
- 69.75 lb and a 4-hour recharge
- 2-year warranty
A durable half-kWh unit for devices and light loads. Dependable, but the low output and slow charging make it a device-first companion.
Best for: Campers charging phones, laptops and lights, not appliances.
Where it falls short:
- 500W output is device-scale
- 120W solar input, slow recharge
