My mini whip antenna requires a 12-15V 100-150ma power supply.
Around the house, I have many power supplies that are labeled as 12-15V and 100-150ma but when measured, are nowhere near the printed output. All are over voltage and current. Not one was true to the label. Not one was under voltage or current.
For example, one that is labeled 9V 500ma - it measures 13v 2.5a, it is 2000ma higher than the label ...
An Archer Universal Adapter that goes from 3-12V in 6 steps is actually 3 (5.2V), 4.5 (6.9V), 6 (8.8V), 7.5 (10.6V), 9 (12.6V) and 12 (16V).
With that said, where can I find a true 12V 100mA power supply
