please don't waste your money on this. First, I have a galaxy tab S8 with super fast charging and when it is charging, it lets me know it's super fast, fast or just charging. This shows just charging. description states compatible with my tablet so there shouldn't be an issue. The adapter is a generic one not even listing 45W but it does come with a 6 foot cable it just doesn't fit properly, which is a problem bc it overheats my device . when you own a Samsung device, get the Samsung charging setup otherwise you're asking for trouble
