Great idea! I already had a magnetic cable on my desk, so I popped a spare USB C tip into my M01:
It’s a much looser fit in the M01 than in a cell phone. I was able to remove it without issue (it pries out with a little plastic tool it came with). It’s not so loose that the tip pops out with the cable, though.
The specific tip came with this cable: Smart&Cool 5 Feet Magnetic USB-C/Type-C Fast Charging. Despite what the item description says about compatibility I am using it with a Smart&Cool Gen4 cable without issue.
I think I’ll stick with this. With the magnetic cable there’s no way to accidentally bust the M01’s USB port by setting something on top of it.
