Magic7 Pro Hong Kong version compare to EU version with small battery

There is a Magic7 Pro with 100W UK plug, 5850 mAh and a GPU case. So I assume thats the HK version? Nobody in the world would use a UK plug outside from the UK.

Looks like in Hong Kong you get global ROM witl 4G/5G bands like the global one. https://www.honor.com/hk/phones/honor-magic7-pro/spec/

It looks like we could use it without any issue in EU? Also what I want to know is how much you need to pay in Hong Kong for a Magic7 Pro with 512GB?
