I found using a fast charger adapter and a standard wireless pad does the same thing my s20 recognises that it's got fast charger attached.

I've got some generic wireless charger which seems to fast charge wirelessly all my devices (S8+, S20 Ultra, S21 Ultra). Rarely use it though since I dislike how long it takes. The key is that it's plugged into a 60W USB Charging hub where two ports support Quick-change (2.0).

Wireless charging takes a lot longer... full stop.

Your phone supports 25w charging by cable only. For wireless it is less.

I believe that the fastest your wireless will charge is approx 7 to 9W... and that is due to technology of wireless in general... and not the specs of the charger.

Just purely the way wireless works by 'inducing a coil' by another coil... it will never be as efficient as a direct charging method.

Unfortunately you cannot break the laws of physics...

Therefore, even with the supposed 'fast wireless' chargers available, it is around a third of the speed. This is why you cannot find one to purchase that states this charging rate... it simply is not possibly wirelessly.

If you intend to just leave your phone overnight on a pad then it doesn't really matter for speed... but if you are in a rush then plug it into the 25W and it will charge from flat to full in around 1hr30.

I have a charger trio wireless pad. It charges my watch, buds and phone all through the night...but takes about 5hr30 to charge them all from flat. If my phone was struggling and needs a boost then I would plug it in...

Kind regards
