Yeah, sounds real convenient when traveling - a differently shaped big ol’ proprietary magnetic puck for each device.
Recharging when travelling is my big concern (well, when I get to travel again). I'm now 100% hooked on wireless charging at home, I've even added the capability to some of my older devices that never leave my home using these (
https://smile.amazon.co.uk/gp/product/B01DLYF1OQ/) so that I can simply pick up things and put them down again onto charging pads around my home instead of having loose cables that I have to keep fiddling with to unplug and plug back in whenever I want to use something.
I wonder whether some manufacturers might be able to re-purpose the form factor of my wireless power receivers, or as close to the size as possible, for a very compact travel charging mat. The pad I linked to is at most the thickness of a credit card and in terms of height and width even smaller than a credit card. I certainly wouldn't mind carrying a charger in this form factor in my travel kit and I wouldn't need it to be super high speed/power. For my use case it would only need to be able to get a full charge into my iPhone 11 Max in the 8 hours or so when I'm asleep in a hotel room (or maybe 6 hours to give a bit of margin for error and possibly bigger capacity phone batteries in the future.
Has anyone actually disassembled a regular charging pad? How small are the actual internals once all the plastic casing is removed? I'm wondering if one could make something a bit like my travel charging mat idea by extracting the innards from a cheap and cheerful charging pad and maybe sandwiching those innards between 2 sheets of thin cardboard or even thick paper. If someone doesn't come out with a proper one I suspect that might become a project for me in 2021 if Apple does go 'completely wireless'
