Anker 535 PowerHouse costs $1270 less. Whether that gap is worth closing depends on what you need to run.

- Anker 535 PowerHouse is 36.0 lb lighter (16.7 lb vs 52.75 lb).
- Goal Zero Yeti 1500 is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
Goal Zero Yeti 1500
The new-for-2026 LiFePO4 Yeti 1500 — a big durability and cycle-life upgrade over the older 1500X it replaces.
Best for: Home backup buyers who want Goal Zero's build with modern battery chemistry.
Where it falls short:
- 52.75 lb — a two-hand lift
- 600W solar input is modest for the capacity

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
