Below rm 100 can get Ugreen or Baseus which is around rm 31.99 to RM 50 which give you 10W Fast Charging and sometime it will peak 12W.

If you can up your budget can get Samsung Fast charge 2.0 type which is RM 300 that can charge between 15W - 17W.

For 3.5mm dongle, is best we wait for Samsung release it’s version whether is it worthy or not as many feedback says that 3rd party one sound quality ain’t that satisfying.

The Wireless Charger Stand? Yea it's already available in Malaysia. Using it right now, to me the fast charging 2.0 is worth it. Never needed to plug in anymore.

Actually, can we use normal fast charger with note 10?

Seems legit to me but the price is rather steep, therefore a turn off with you ask me. I have seen legit unit with much more affordable pricing from Preferred sellers on Shopee.
If the unit is genuine, that it's quite the steal. Just check the warranty if the phone has been registered.
