Hello there, hope we're all well.
Does the 45 watt fast charger charge with Super Fast Charging speed? I did some googling and, accoring to that, the super fast charge only needs 7.5 watts so I would like to say yes to this. But am not sure.
To use Super Fast Charging 2.0 on the amazing S20 Ultra 5G you need your phone, a C-to-C cable, and the 45W Travel Adapter, which is a USB-C power adapter that gives you a major boost of power.
Super Fast Charging 2.0 is only available on Galaxy S20 Ultra and Note10+ with 45W Travel Adapter (PD3.0 standard) and 5A C-to-C Cable, which are sold separately.
