Need a Converter

12 VDC cigarette lighter plug to 9VDC battery connector.   On Amazon,  I get vast numbers of discrete components.   What magic phrase am I missing,

  1. Not that long ago, you could get one at Radio Shack. Nowadays it's harder, at least the "9v battery connector" part is. Here is a 12vdc-->9vdc converter, and there are others in the "similar items" below:

    https://www.amazon.com/Phimore-Regulated-Mobile-Converter-3-6-9-12/dp/B00G75GKYC/ref=sr_1_4?ie=UTF8&qid=1522276129&sr=8-4&keywords=car+converter+12v+to+9v

    Here are 9v battery connectors, but of course you can buy a pile of them for about the same as you pay for one:

    https://www.amazon.com/s/ref=sr_pg_5?rh=i%3Aaps%2Ck%3A9v+battery+connector&page=5&keywords=9v+battery+connector&ie=UTF8&qid=1522276526

    Hope that helps- it's getting harder all the time to adapt "old tech," so that it can still be used. (That's why I no longer work as a stereo repairman.)

  2. Something like this?

    I Googled "12v to 9v converter cigarette lighter" to find that.

    Earlier results were mostly buck converters for circuits.

  3. Looked on Amazon, found 12v to 5 v converters. I wonder if suppliers for model rockets or recreational drones might have something? Maybe check at Greybar Electric?

  4. I understand the cigarette lighter connection, but am unclear as to what the 9vdc side looks like. Can you elucidate?

  5. Without knowing the current (amperes or milli-amperes), the answer cannot be answered.

    How ever, "9 volt car adapter" will show you examples.

  7. This appears to have the right ends. Doesn't appear to convert to 9V.

  9. And then, on Amazon, this, after a few pages of non-battery-plugs:

  10. Seems there are a lot of 12V to 9V converters. What they don't have is the 9V battery connector.

    Scavenge the connector from an old transistor, radio or just buy one here:

    Solder it onto the leads from the converter, if you don't mind that kind of project.

  11. Sorry to be nosey, but what are you trying to plug in? Maybe that would allow us to offer better solutions...
