Hello, all:
I purchased a 12V power socket
this one:

And installed it in my dash. It powers my handheld spotlight just fine, but it will not work with any USB plug in adapters I have - and so far I tried 8 different models! Anyone know what's up with this and have suggestions for a model that is sure to work with the USB adapters? I wanted to get a USB adapter with a voltage readout, but two of them it tried do not work, and a bunch of other models even with indicator lights do not work.
