The next generation of power is here! Introducing the all new Yeti PRO 4000 portable power station with dramatically more power and faster charging than previous generation models. Plus, its updated LiFePO4 battery tech means it can last for over 10 years—even with daily use. Use it for emergency home backup, take it on the road, or pair it with solar for renewable clean energy.

Build out your backup system with powerful expansion batteries. You can combine as many as 4 Tank PRO 4000 batteries per Yeti PRO.
