S9 AC Adapter not capable of fast wireless charge?

[SpookDroid]

I'm having an issue with my S8
I have no issue with wireless fast charging but I can't get it to Fast charge when plugged in to the fast charger the phone came with. I also purchased another one made by Samsung but it will not work plugged in either.

It starts to Fast charge then after a couple seconds it goes back to "Cable Charging" or worse yet "slow charging.

Try booting up into Safe Mode and make sure that you're using the cable supplied. Also, check a couple outlets, some people reported that low-voltage in the outlet caused their adapters to act strangely. If it still fails, you might have an issue with your USB port. make sure it's clean and not wet or wobbly.

I'm totally confused so I'm just going to buy one of the pretty, stylish, white Samsung wireless stand chargers for my Lilac 9+ that will be here tomorrow
