Will be getting a Pro 12.9 2021 next Friday! Coming from an Ipad Pro 10.5 (which has served me well) so I'm excited about the upgrade. I'm not too familiar with Thunderbolt however. What exactly should I stock up with? Should I buy a Thunderbolt 3 USB C-Hub? I see some cheap ones on Amazon and some more expensive ones. I'm looking to hook up the Ipad to a monitor using HDMI, load the occasional SD Card, and hook up an external hard drive as needed. I'm confused about the charging as well- one hub I see on amazon says it will charge at 100 Watts; will that work with the Ipad (or is it even needed)? Thanks!
