Would third party adaptor charge Lenovo Legion Y700 Gen4 at full speed

I don't know where to ask this, I hope asking here is appropriate

The official charger from CN doesn't have the plug I want so I thought maybe I could buy a third party charger. But I'm unsure whether it will charge at full speed.

Should I find a Lenovo official charger with Type-G plug or just any third party charger that supports up to 68W.
