Is it normal to take so long?

Hello, is it normal for my newly acquired Tab S9 to take 4h20min to charge fully from 22%? I know that it is learning my usage patterns and that I'm not using a samsung charger but it seems a little excessive.

Also, the tab was listed as an "exposition article" but it is practically brand new. Are there any settings I should activate to protect the battery, since I don't know what's its health state?
