Your variable defense against martens: Either connect the device directly to your car battery. Supply it with power via USB, e.g. via a powerbank. Or simply insert batteries. The repellent device will reliably keep the unloved rodents at bay!
Note: For optimal functioning, we recommend that you wash the engine or use a scent mark remover before use and clean the car parking space. This will eradicate any residual scent from previous marten visits.
