Dash cam power source?

[Cole]

You could try buying an after market USB lighter adaptor and gut that... Otherwise you need to delve into the world of electronics and make something up with an LM7805

How does the manufacturer of your dash cam expect you to use it in the car if they don't supply a 12V feed? Is it a GoPro or something like that with its own battery?

Got any suggestions for a quick and dirty 12v->5v regulator? I'd gut the lighter adapter, but mine didn't come with one, just a mini-USB charge cable.
