B4000 SST

SST Power Station

Setting the bar for professional power stations. The B4000 doesn’t just deliver extremely high output, it does so with a class-leading power-to-weight ratio. Thanks to solid-state technology, it provides more power per pound than any other power station—and it’s safer, too. With 4,000 watts on tap, it’s perfect for home backup and even includes a 30-amp RV outlet for recreational use. And despite its capacity, it can charge from 0-80% in just over an hour.

Solid-State Battery

Higher energy density and no flammable liquid electrolyte means more power in a smaller, safer package than traditional lithium-ion batteries.

4000W / 2611Wh

Rated for 4,000 watts with peak power of 7,200, the B4000 SST can run household appliances, desktop PCs, power tools, and more. And with 2,611 watt-hours of capacity, it’s the perfect backup power solution for your home during a blackout.

Fast Charging

Even with its extreme capacity, the B4000 SST fast-charges up to 80% in just over an hour and 100% within 1.5 hours using AC input. Using the 12V vehicle adapter, a full charge takes 12 hours, while charging with 600W solar power from optional Yoshino solar panels takes just 5.5 hours.

It’s All in the App

The Yoshino mobile app unlocks additional features of your power station. Monitor charge level, battery health, connected devices, and more.
