I have a Canon PowerShot G7X Mark II - I have been using SanDisk Extreme PRO SDXC UHS-1 Cards - 64 GB. I am going on a longer trip and would like to get some extra cards.  Will the Sandisk 128 GB Extreme Pro SDXC UHS-1 Card work in my camera?
I have a PowerShot G7X Mark II.  I will be taking a trip to Southern Africa (via the UK) next year - how do I handle my battery charger outside of the US?  Is there some sort of adapter I should use?  Thank you.
