How to Power MB SD Connect C4 wihtout Vehicle?

 How can i power the mb sd connect c4 without vehicle?

Of course:

You just need a 12V source and at least 1A.

If you use the EOBD cable, you have to connect pin 16 to positive and pin 4 or 5 to negative, you can use an EOBD connector from a vehicle with its respective cables or use female connectors on the SD Connect cable.

If you use the banana cable, you only have to use the black and red ones that have the polarity marked.
