    Powering Edison in a car

    Bill.

      Hi,                               

       

      My 2013 Honda has 2 power sockets. The owner's manual states:

       

          "The accessory power socket is designed to supply power for 12 volt DC accessories that are rated 180 watts or less (15 amps).

          To prevent battery drain, only use the power socket with the engine running.

          When both sockets are being used, the combined power rating of the accessories should not exceed 180 watts (15 amps)."

       

      The sockets look like the old cigarette lighter holes. I found an adapter at Sparkfun.com that would plug into the power socket, To it I can attach wires:

      They also have a barrel jack adapter to which I can attach the wires from the above adapter:

      Looking at the Hardware Guide, section 3.6:

      http://www.intel.com/content/dam/support/us/en/documents/edison/sb/edison-arduino-hardware-guide.pdf

       

      I see that the 12v in the car falls into the 7 v to 15 v range.  I don't know what to think about the amperage.

       

      Question: is the power socket a safe source of DC for Edison?

       

      Regards,

      Bill

          Hi Bill,

           

          I would love to help you with this.

           

          I think that you shouldn't have problems using the power socket, because the Edison is never going to need more than 15 A, so answering your question, yes it is a safe source.

           

          Having said that, the only recommendation that I can give you is to make sure that the Car Adapter Plug provides enough current to power the Edison, the Edison is not going to draw more than 500 mA.

           

          I hope you find this helpful, and don't doubt to contact us when you have questions.

           

          Have a nice day.

           

          Regards,

            I don't think there would be an issue with hooking up the edison to the car battery. The edison will draw the amperage needed on it's own, but it will be far and away less than .5 amps, so you shouldn't run into issues.

             

            (Disclaimer, I have not done this.)

              Douglas,

               

              Thanks for the response. I will look for an Electricity 101 course to make me more self sufficient

               

              Regards,

              Bill
