It has exactly the magnet strength needed, so you can easily handle the phone and charge it without disconnecting the magnetic plug, but if you push it to the limits that a regular cable might bend or break, this one simply comes off!
However, its great advantage is that with the same cable, you not only safely charge the phone but also connect it to a computer and transfer data at high speed.
The cables interchange between themselves without any problem, even for the 3 different micro-usb + type-c + lightning connectors.
The only downside is that there are no longer cables and separate extra connectors available.
