Hi Andrew - sorry to be replying late. Not sure we're allowed to link to other "seller sites" on here - but the magnetic adaptors were totally generic, bought of a "well known auction site". There's a number of them out there - and so far, they've all been compatible with each other. Search for "USB magnetic connector" or something like that. Comes in MicroUSB, Usb-C, and also Lightning (I think?).
