Your phone has a microUSB connection which, these days, is as ubiquitous as the iPhone one. You'll be able to get an in-car power socket adapter from just about any supermarket, no need to look for specialist outlets.
The charger I have for my old mobile phone will charge my tablet and new phone but very slowly, it is not powerful enough to keep the tablet charged whilst it is being used as a satnav.
I was given a new charger for the tablet some time ago that is powerful enough and I need to buy a similarly powerful charger for the phone.
