I have this 5vdc wall adapter that works with an smps transformer and after a year or more it has increased in voltage anywhere from 3 to seven volts.
Now I'm aware that some of these require a load to operate at their normal voltage but this one tested 5 maybe 5.2 volts without a load when new and has now jumped to 14 vdc and has settled at 8 vdc without a load.
I was using it for a clock and it killed the voltage regulator when it climbed to 14 vdc.
I'm wondering what would cause such an increase in voltage?
