Goal Zero Yeti 1500X 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 $1570 less. Whether that gap is worth closing depends on what you need to run.
- Goal Zero Yeti 1500X holds 196% more energy (1516Wh vs 512Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 1500X has 2750W more surge headroom (3500W vs 750W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker 535 PowerHouse is 28.9 lb lighter (16.7 lb vs 45.64 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 1500X. 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.
The previous-generation flagship. Its NMC battery is the catch — far fewer cycles than the LiFePO4 units now around it, including its own replacement.
Best for: Only at a steep discount against the newer LiFePO4 Yeti 1500.
Where it falls short:
- NMC chemistry — roughly 500 cycles vs 4,000 for the new 1500
- 180-minute recharge is slow
- Only a 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
