Help Di2 charging via USB

[leyorkie]

As the title, I’ve misplaced my charger so an internet search says use a standard good quality (iPhone) charger.
Anybody done this?
I’m OK for a while but I’ll need to charge eventually.
Internal battery if that makes any difference.

Thanks
Edit,
Just remembered that the cable connection has two pins with an offset location pin so I think I’ve answer my own question.
Not without the correct cable!

Yeah you need the adapter block which does some sort of conversion. Really annoying they couldn't just fit micro-USB conversion internally to the junction boxes!
