Hi. I don't know much about electronics, but I thought it would be ok to connect a 3-way car lighter adapter directly to my car battery and use it to power my electronics like a Garmin GPS and Stereo, but when I plug in the garmin, it does not charge, and my stereo will not turn on either, however, my 12v dc car fan will work when I plug it in. Each of these items has a male cigarette lighter plug that goes into the female 3-way cigarette lighter adapter I bought.
Do I need to place a resistor in series to lower the current going into my garmin and stereo?
I am clueless,
Please help me if you can.
Thank you
