Are car charger splitters safe and okay for my car?

Are car charger splitters safe and okay for my car? - 1

Added (1). I have a 2002 Nissan Altima. It only has one charging socket in the front and one inside the center console. Can I plug in a 3-way splitter in the front one, so that I can plug in my GPS, iPhone, and FM transmitter in at the same time?

You won't hurt your vehicle. If too much current is drawn, a fuse will blow. Then you'll know you have too much plugged in. But all that small electronic stuff doesn't draw much current.

Hi perhaps a bit more detail is required sunshine.

Your 'Aux' socket will probably be covered by a 10 amp fuse. The items you mention would probably only draw about 3 amps combined.
So. Yes. Like 'M.' said. Perfectly safe.
