You should always replace electrical components with OEM parts or aftermarket parts that match all specifications. Going off spec can cause electrical failure and result in component damage or worse.
Idk about the Razer Blade but, with my OnePlus N10 5G, it won't do it's 0-100% in 30 minutes without the original charger and charging wire at 60w 6.5A output or something equivalent. My numbers might not be exact but their close and hopefully, with the info I have provided, you and others get a better feel of what you would rather have.
I just found 616 upvotes for offbranding on r/frugal. I've heard high-quality full-spec OEM is important but idk, I've never seen anything bad happen due to offbranding. Ofc OEM gonna say "OEM only" bc $ but even OEM Samsung's can blow up yo. I say save yourself some money.
If you don't use the proper charger with the correct wattage you risk damaging the battery and or yhe entire unit
