Battery & Specs
At the heart of the Yeti PRO 4000 is a LiFePO4 battery, offering:
- Long lifespan: Over 6,000 cycles to 80%, making it a decade-long solution for many users
- Safe chemistry: LiFePO4 is thermally stable and non-toxic
- Smart monitoring: Track battery health, usage stats, and charge/discharge rates via the Goal Zero app
Total usable capacity is just under 4kWh — enough to power:
- A full-size fridge: ~24-48 hours
- Wi-Fi + lights + laptop: 3–5 days
- CPAP machine: ~50+ hours
Portability & Design
While the Yeti PRO 4000 is not exactly “portable” in the lightweight sense, Goal Zero makes it manageable:
- Integrated rolling cart with rugged wheels and telescoping handle
- Modular form factor means it stacks with expansion batteries cleanly
- High-contrast touchscreen on the front panel for direct control and system monitoring
At 115 lbs, it’s a two-person lift without the cart, but very manageable when rolled.

This makes it suitable for both rapid grid-top-ups and sustainable off-grid recharging.
