240v to 12v socket Page 2

To run 12V gear from Australian mains, use a regulated 240V AC to 12V DC power supply feeding a fused cigarette-lighter (female) socket.

Pick a supply rated for at least the device’s draw plus headroom—e.g., a fridge pulling 6A wants a steady 10A–15A unit; tiny gadgets survive on 2A–5A.

Mind polarity: centre pin of the socket is usually +12V, outer is ground, and fit a 10A fuse close to the supply for sanity.

Avoid bargain-bin “unregulated” bricks that sag under load; quality units output around 12.0–13.8V and don’t cook cables.

And remember: 240V bites—if you’re not confident with mains, buy a pre-made adapter or get a licensed sparkie to wire it up.
