Sure! The charger works great, but I wish I could have found a stock one from Huawei. I love the case. It has a zipper pocket that fits the USB C hub and mouse perfectly, and the handle is convenient if I need to take the laptop somewhere by itself. Otherwise, the handle just slips in and becomes flat. The USB C hub is one of the only ones I could find with all of the ports I wanted, most of the others were always missing one of them. I don't think the cooling pad is necessary, I just got it because I would sometimes be away from my desktop and playing AC Odyssey or Destiny 2 got the MBX Pro very hot very fast. Sorry for the giant reply, and let me know if you have any questions!

I used my iPad Mini 4 as a primary device for a while. Sold it because it got very slow and I wanted to cut my losses when the new model was announced. I used the Microsoft Foldable Keyboard but have also heard good things about the Logitech Keys-To-Go and Brydge 7.9. I am probably going to buy the 2019 model sometime before I go back to school—it's a great device for both traveling on trains and planes and studying.
Other must-have accessories are a portable charger, a wireless mouse for iPadOS, a stand, a game controller, an Apple Pencil, an Apple Pencil charger or a hub, a guitar interface if you make music, a case, a screen protector, and a bag.
