OK, so this is a bit if a 'noob' question.
I am finding the whole concept of 'fast' and 'super fast' charging very confusing.
The S22 Ultra can accept a 45W charger. OK so I bought a 45w PD power bank, but when I plug it in, the phone says 'fast charging'. When I use my old (presumably 15w?) Samsung charger, its says 'super fast charging'. When I use a (non-Samsung) 45w pd charger it says 'fast charging'
So it appears I only get 'super fast' charging when using my 3 year old Samsung charger, which is NOT 45W! I'm not good at maths, so I don't really understand voltages and amperes either (said I was a noob!).
I guess what I want to know is, should I buy the Samsung 45w charger, will it make any difference to the charging speed? It takes about 2 hours to 'super fast' charge the phone at the moment.
Thank you.
