This is about the phone Samsung Galaxy S4 mini.
I got it second hand.
It came with a small mains plug shaped adaptor which connects to the
phone with a USB cable.
This cable has a "normal" USB plug on one side and a mini plug on the
other side.
This cable is very short.
I have a longer cable with the same plugs which seem to fit physically.

- Can I use the other cable safely to connect to the PC and/or to the
mains adaptor?

- Can I connect this phone to my (TomTom) USB car adaptor?

In other words: how universal is USB?

The phone manual warns not to use non-original accessories...



In theory _Universal_ Serial Bus is universal. That said, sometimes
manufacturers don't always follow the rules and quite often the hardware
is pure crap. A high-quality mains charger or car adapter and a decent
cable (Anker braided is my favorite) won't do you wrong. I would never
trust the cheap clone adapter and thin cable picked up at the local
discount store with any of my equipment. You should be aware that not
every charger will support every proprietary quick-charge scheme that a
randomly-chosen phone maker dreams up but that only means that charging
will take longer -- no damage should ever ensue if a proper but
non-original USB charger is used.



OK, the main thing is that I don't risk blowing up anything.
One of these days I'll try out testing these in practice.
