    We have a 2017 Prius 3. We have a dash camera located in the mirror. We could get power from the cigarette lighter, but then we would have a long cable hanging. We would like to get power from the overhead console. Any suggestions?

    You won't find any 5vdc in the console. Did you mean 12vdc?

    No, I was hoping for 5VDC, but 12 VDC will do as I can use a step down transformer.

    If you do that, you need to use a transformer/power supply that came WITH the camera.....or is made for that use.
    And ......simple transformers do NOT work with DC power.

    Was that a typo when you said the camera is IN the mirror ?
    Did it come with the car.....or the mirror ??

    A 12vdc to 5vdc solid state converter is cheap and easy to find on eBay. I do not know about the availability of 12v in the overhead. Since the garage door opener is up there, I would guess that 12v is also.

    Agreed, since there are dome lights as well.

    To Sam Spade: Sorry for not replying to all your message. I have a step down transformer ordered. I will tap into a 12VDC source in the dome light area and plug in the transformer. From there I will power the mirror mounted camera. The dash cam will store video on a 200 + GB card.
    The car did not come with a dash cam, I got it in China.

    Please consider my question answered and many thanks

    Great. Looks like you have a good plan.

    BUT......referring to the part you ordered as a "step down transformer" is wrong and confusing.
    If it really IS just a transformer, it will NOT work for what you need.

    Using the right terms to describe things is important.
    If you want wine, you don't order grape juice.

    Most likely it is a mobile 5 V power supply, which is somewhat more than a simple transformer.

    Isn't USB 4.5 volts ?
    And USB might not supply enough current for the camera either.
    But it might be worth a shot; probably wouldn't hurt.

    I stand corrected on the USB voltage.

    My dash cam says it requires 5V 800 mA. So this converter could power it 2 1/2 times.
