100w Charger (Rog Ally X)

Can anyone recommend a good Rog Ally X charger that supplies 100w? ASUS official ones are sold out.

I purchased one off a website but after reading reviews they seem to be fake ASUS cables that are sent out (UK-chargers com).

I don’t want to risk the Ally or my home tbh. My friend’s house burnt down for a knock off iMac charger, so taking no risks!
