Unfortunately my armrest doesn't have a 12v port in it

It's easy to add a spare one, just spur off the existing one.
You could put the socket behind the dash trim and then run the cable between the radio fascia and the dash trim, there's usually plenty of little gaps or trim overlap to enable this.
One like this may be of use-

Failing that there is a company called Brodit that produce cradles and dash mounts that may be more your cup of tea.
They're not cheap but will enable you to hardwire a charger cradle to the car and avoid wiring in extra 12v sockets or run visible cables-

I have numerous Brodit mounts in my work car and they are sturdy and very user friendly.
The hardwired mount as above is best fitted by a qualified auto electrician so as to ensure that it's done right and the cable is thin enough that it will be easy to fit through gaps in trim.
I highly recommend Brodit products and think it will be your best solution.
