Thanks, useful stuff indeed. I'll be making a 'multi-use' cable with right-angle micro usb on one end and some sort of 2 prong connector on the other end(have all kinds in my stash) that can be fitted to any 5v 2a charger(any will work). The aim would be to use with a car charger or longer cord wall charger
