If the Dash Cam is hard wired or plugged into the cigarette lighter socket (automobile auxiliary power outlet) each time the car is turned off the Dash Cam is turned off, and each time the car is started the Dash Cam and its camera’s are turned on.

Realizing that the Dash Cam could also be powered using the USB Battery Power Supply and I already had Nordic batteries in my garage, and had recently purchased the USB Power Supply Nordic unit, I thought it would be an excellent idea to try to power the Dash Cam with the USB Power Supply.
(You may need to check for the power details of your own Dash Cam before you try this idea out.)

I connected the USB Power Supply unit up to the Dash Cam and it powers up perfectly.

An extra bonus is the switch at the top of the USB Power Supply means that the Dash Cam will work as long as the switch is turned on.
If I were to get out of the car I can turn the USB Battery unit off and the Dash Cam turns off, or I can leave it running while I am away from the car and the Dash Cam with front and back camera views can keep an eye on people approaching the car or any mischief that they got up to.

This is extra helpful if I walk around the car or at a company/school site and the camera is left on and my moments are recorded.

I hope that other companies make these USB Power Supplies that connect to their tool batteries.
If they do, you can possibly use them for your own Dash Cam. Please do your homework first to ensure that the voltages and so on match up safely.

All the best from
