Silent auction. Loud impact.

KOSTAL has a very special promotion for its customers: Together with renowned graffiti artist Jörg Schünemann, alias ‘Dosensport,’ the company has designed twelve individually designed ENECTOR wallboxes in a unique street art style – as a symbolic eye-catcher for sustainable mobility.

These unique items will be auctioned off in a silent auction, with the proceeds going to charitable initiatives as part of WDR's Christmas miracle campaign, including food banks and international projects run by ‘Aktion Deutschland hilft’. The campaign, with the slogan ‘Silent action. Loud impact.’, raises awareness of sustainable technology while emphasising social commitment.
