300W GaN Charger for Legion Pro 7

I’m looking to buy the Chinese Legion 300W GaN charger as a portable charger for school for my Legion Pro 7 16IAX10H, does anyone have experiences with it?
- I’m concerned if it will mess up my computer since it’s the overseas version and I currently live in Singapore (I’m a noob when it comes to PCs so I asked AI, it said as long as I have an adapter I should be fine…?)
So… would I be good to get this charger? Thanks in advance.
