The bundled cable is DN980 model - a black 1m cable with 3A rating, which provides up to 25W charge. If you want to utilize the maximum 45W of a compatible USB-PD power adapter, you will need a 5A-rated cable. Or you can buy the most recent 45W EP-T4511 Samsung charger, which comes with a 5A cable inside (as do the previous iterations).
