Where to get device to keep power on to device for 2-10 minutes after the car turns off?

Question

I need to be able to have power drawn from my car battery for 2-10 minutes (either that I can set or device limit) after the ignition shuts off.

As an example, what if I want a new car radio to continue to play for 5 minutes after I turn off the car and then have the power to it cut off? If tie directly to the ignition switch for power, it would turn off when the car is turned off.

I was thinking a simple solenoid would do this, but I cannot find one.

Any ideas on other ways to do this? Can you provide a link to where I can buy what I need?

I have looked for the light fuse that allows your headlights to turn of up to 180 seconds after the car turns off, but Radio Shack or any of car shops in town do not know where to get them, b/c they claim they do not have them. Perhaps they do, and the reps just do not know.

Links to any online?

To the second question/answer, I have a Subaru.

The issue is that I need the device to cut off after some amount of time, probably no longer than 20 minutes after the car shuts off, to avoid the battery being drained. The radio example you gave is a good one, in that the memory for the settings does not require much power, but the other 99% of the radio is not connected to the same part of the iginition switch. Otherwise, if you left the radio on, you would drain your battery completely in a short time.

Answer 1

What type of a car do you have?

In most new cars (if not all), the ignition has three settings: off, power on (but engine off), power+engine on.

Listen to the radio in the power on option.

Each car radio has also the option to get constant power (even if ignition is OFF) so that the memory settings don't go away (radio stations, etc.).

Answer 2

If in the US, they sell a device for the light fuze that will turn off your lights after so many minutes. But it only works on the newer cars. You could check on this. Then run ;your power to the fuze.

Then check with Radio Shack, they should have what you want.

Answer 3

After sitting right here for 5 minutes, hurting my mind attempting to imagine of yet another one to operate and failing miserably, i am going to easily say that become an mind-blowing record. I rather like the Eiffel Tower one. it is rather real too! :p i have realized that existence will be *a lot* more suitable interesting with a soundtrack. i want to employ a guy to follow me round for an finished day, playing the proper music in any respect cases.
