As I was watching you put the keyboard in that slot I had an idea to protect said keyboard from the charger. Turn the keyboard so the keys part is facing the front cover and the back of the keyboard is what you see when you open the case. You could also put the charger and cable in that section for the mouse to have more room on the other side for stuff!
I have had Tomtoc cases for mine and my husbands Nintendo Switch. They have held up for 3.5 years. I have a Zugu case for both my ipads. They are very durable but add weight to your bag. I only take my 11” ipad out of the house. I use a 2 meter long cord. Finding something that holds everything has been futile.
I’ve got an iPad Air 3 and have a combo case and keyboard. My issue is finding apps to store my writing as I don’t use the cloud. I’d love any reviews of decent apps and ways to store work.
