Anker 535 PowerHouse vs Goal Zero Yeti 1000X
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 $770 less. Whether that gap is worth closing depends on what you need to run.
- Goal Zero Yeti 1000X holds 92% more energy (983Wh vs 512Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 1000X has 2250W more surge headroom (3000W vs 750W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker 535 PowerHouse is 15.0 lb lighter (16.7 lb vs 31.68 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 1000X. 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 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
The older X-series 1kWh. Rugged and expandable, but its Li-ion cells and 2-year warranty look dated next to the LiFePO4 6th-gen Yeti 1000.
Best for: Only at a discount against the newer LiFePO4 Yeti 1000.
Where it falls short:
- NMC — ~500 cycles vs 4,000 for the new Yeti 1000
- 2-year warranty
