Cigar Lighter Transformer Lead.
12v input to 5.8v Output.
Switching Circuit Battery Saver.
A very good quality cigar plug lead to an enclosed transformer unit originally made to provide auxiliary power for a battery operated device made by Ora Electronics, it has a small circuit board inside with a coil transformer, various capacitors, resistors, diodes and semiconductors ie B-772-Y(TO126), KSP2222A, Z440.
When plugged in to the car cigar lighter socket the output is a steady 5.8 Volts, – not sure if this is regulated output or not, but for the money why not experiment with one.
These Ora adaptors came to us as part of a lot of surplus stock. They are in original sealed packaging and as new in all respects but having been in storage for some years we have classified them as ‘new other’
