Einhell

Einhell was founded in Lower Bavaria in 1964 and has turned from a tool mail-order house into a battery platform company.

The core is Power X-Change: one battery for well over a hundred machines, from drill drivers to lawn mowers and hedge trimmers. Anyone needing several tools buys them bare and saves – though the maths only works inside this system. The tools target house and garden, not continuous trade use.
