Hello,
I have a triple socket car cigarette adapter for powering multiple 12v devices from a single cigarette lighter outlet.
What's odd is that there is a USB port built in and it works BUT....
I opened it and the circuit board is unbelievably simple....only a led power indicator, what looks like a transistor and a resistor. That's it.
All the other USB cigarette power devices I have that have a USB port have a 34063A chip and much more components like capacitors and more diodes and resistors etc.
How can this ONE be so simple and still work?
