The NOCO GB40 is not specifically designed for electric vehicles such as the Hyundai Kona 64 kW. It is mainly designed for petrol and diesel drives and does not support a direct jump-start function for electric vehicles, as these do not have conventional batteries that need to be started. There is no direct jump-start method for electric vehicles as there is for combustion engines. If you have problems with your Hyundai Kona, you should contact a specialist.
