The perfect combination of fresh ambition and years of knowledge

The Kempower story started in 1949 when Martti Kemppi and his brother founded Veljekset Kemppi Oy, later also known as Kemppi Oy, a manufacturer of premium welding power sources. Business was strictly welding, but between 2012 and 2018 it became clear that the future was electric and, since Kemppi already had years of knowledge in charging solutions, Kempower Oy was founded. We continue in the footsteps of Kemppi in perfecting infrastructure worldwide – now with electrification and reliable EV charging solutions. We manufacture all our EV chargers in our factories in Lahti, Finland – side by side with Kemppi welding power sources.
