Re: Maintaining power to a car FM transmitter
One option I can think of right of hand would be to buy a decent sized capacitor and a diode with low voltage drop and wire them so that your car charges the cap and the cap is directly connected to the socket. Another option would be to add another socket to your car wired from the battery and fused live (on) all the time.
I have done both options but liked the later better. It is also convenient to have this other socket for running a charger for something while the car is off or running an inverter for someone playing on a game system in the back seat...
The reason for the socket losing power is from the contacts in the ignition switch opening momentarilly.
