A:AnswerHey there, Alfie! The Galaxy A01 is not compatible with this charger being that it does not support wireless charging. Thank you for asking this question. ^Kayla
A:AnswerHi!
Sorry, can't answer that for sure. I just bought a new IPhone 12 Pro Max with an Otterbox outercase. I couldn't charge it on my old charger however, the Samsung works perfectly. Hope that helps.
A:AnswerI can only answer this way. I used it with a note 8. I had at home the old fast charge that came out with the note 8/ s8 and this at work. It did charge faster then the original charger by at at least 40%. So my hunch would be the same for the S9.
A:AnswerYes, it will. I charged my boyfriends S8+ before I gave him my S10+ and bought the Note 10+. You will love this charger and you won't regret buying it. I put my phone on the charger any way and it charges it upside down, sideways, and upright.
