I would think you could still just take a lightning cable for your iPad and iPhone. It's obviously still going to have a lightning port.
The only thing I don't like about wireless charging is that it means another device specific cable to schlep when traveling. I've already experienced this with Apple Watch. Now it will be +2. Previously I could just bring one cable for phone, iPad and Air Pods and then the AW cable. Now I'll need to bring a cable for iPhone, a cable for iPad and Air Pods, a cable for Apple Watch, a cable for Garmin. Ironic that wireless doesn't equate to traveling wire-free.
But big picture that is a small inconvenience (and $ price) to have inductive charging devices at home.
