QuadLock USB phone charger install on a BMW R18 First Edition

I have a BMW R18 that I love but it lacks a port for a phone charger. There are a couple of videos showing how to install chargers on BMWs but I could not find an English version. I'm by no means a professional, but this video shows how I did it. BTW How many bolts, tools, etc.. did I drop in this video -LOL 1:20 remove the seat 2:00 Remove the battery 3:04 Remove the engine cover 4:55 Remove the fuel tank
