Plug on Gs 800 need help please

[Voetpomp]

I have a 2012 Bmw 800 Gs and want to know if you can get a plug that converts the plug next to the key /ignition so that it is the normal size of a car? Or is there a issue with the voltage. Want to use it to charge a iphone while riding or blow up a matrass once at the camping site.

Thx.
