A WALL WART 12 26 2020
That is a name someone gave to an AC Adapter per Wikipedia.
But a problem that a lot of people who want to videotape their musky fishing adventures have is that the camera batteries run out and they keep having to replace them.
Several years ago I attempted to remedy this problem by installing a 12 VC DC to Camera input Voltage DC Convertor. Thereby converting the Boat Battery to continuously power the video Cameras. I matched the DC voltage of the small adapter to that of the output of the AC to DC Adapter that came with the camera.
But it didn't work. And I was lucky that I didn't fry the camera! So I analyzed the current coming from the AC to DC OEM Adapter to that of the DC to DC adapter and it wasn't in the same "form." I believe that one of the two trickled and stopped and the other was different than that.
So I was researching this on Wikipedia today. And here looks to be the main crux of the issue with regard to it. So indeed these are the electrical variables that need to be solved.:
"Originally, most AC/DC adapters were linear power supplies, containing a transformer to convert the mains electricity voltage to a lower voltage, a rectifier to convert it to pulsating DC, and a filter to smooth the pulsating waveform to DC, with residual ripple variations small enough to leave the powered device unaffected."
And hopefully mfgs will supply a continuous power 12v to camera v adapter. I am not sure if you have that cigarette plug adapter if it will give you continuous power or is just used for charging and won't charge while camera is in use.
But put very simply here is a great market need that isn't being addressed by the manufacturers of these devices!!!
And I am not going to rub Corporate Americas flat bridged nose in it by asking, "How come you couldn't figure this market need out already."
