Why SEQUOIA?
The sequoia is the oldest and strongest tree in the world – it lives for over 3,000 years, survives every storm and frost, and its strength is legendary. Even a direct lightning strike cannot destroy a sequoia – its internal structure is so resilient that it regenerates and continues to grow for centuries.
Exactly the same features characterize our PowerBox Wallbox SEKWOJA 11 and PowerBox Wallbox SEKWOJA 22 series charging stations.
