I'm looking to buy a wall plug for my samsung wireless charger portable battery but I'm struggling to find one, I have a 25w USB type-c one spare that came with my s20, since the battery pack is charged using a type-a wall plug would it be possible for me to buy a type-a to type-c adapter and use my 25w type-c plug? I'm sure it works I just want to make sure a 25w adapter wouldn't be too much.
