====== 12v house power outlets ======

Full-timers and those with more robust system will likely want to install [[electrical:12v:intro|12v power]] outlets in their van.  Doing this means one can move electrical items around and plug them in where you want them. 

===== the cigarette outlet =====

[[https://amzn.to/3efQlRr|{{ https://m.media-amazon.com/images/I/81u2V1SiFkL._AC_UY218_ML3_.jpg?175}}]]
The most common 12v outlet is the cigarette lighter outlet.  The [[https://amzn.to/34wcUNa|version shown here]] has [[electrical:usb|USB outlets]] built in, also.


Pro:

  * universal((although there are proprietary versions like the [[https://amzn.to/3hJ0l88|DIN Hella]] found in BMW motorcycles and some European vehicles, etc))

Con:

  * large
  * typically limited to 10A or so
  * notoriously unreliable, although [[https://amzn.to/2yPXqYr|Blue Sea makes a locking marine version]] that is robust

If you must use a ciggy port considering plugging in a [[https://amzn.to/2TrtwUZ|wired extension/splitter]] as a sacrificial lamb.  *When* the port dies it will be the replaceable extension and not the built-in port. The *wired* part is important, since it will flex and place no strain on the port. 

==== breaking the 10A barrier ====


[[electrical:12v:ports|Ciggy outlet]] power is typically limited to 10A (~120w).  

If you wanted to extract more power from the alternator you could wire in [[electrical:12v:alternator|an isolator]] (plain solenoid or VSR).  Instead of feeding an auxilliary battery this isolator would be used to pull more current into the living area.  You could run 12v loads directly, or attach an inverter's input wires to the isolator's outputs.((positive to isolator, negative to chassis ground))

===== other connector types =====

Advanced users often cut off the ciggy plug and use something superior for their needs. 


==== Anderson ====


[[https://amzn.to/2RARuZZ|{{ https://m.media-amazon.com/images/I/41U3vF1-mcL._AC_UY218_ML3_.jpg}}]]
The most common non-ciggy connector is the [[https://amzn.to/2RARuZZ|Anderson Powerpole]].

Pro:

  * when assembled correctly, polarity is assured even when you aren't looking 
  * slide together in pairs in different arrangments and directions
  * robust, especially for frequent connects/disconnects
  * [[https://amzn.to/3eiTuQj|power distribution blocks]] can be very neat and small


Con:  

  * more $$$
  * need to be assembled((pin on wire, pin into connector, neg/pos connectors mated together))
  * the different possible arrangements means you'll need to pick an arrangement and stick to it
  * a [[https://amzn.to/34wcUNa|special crimper]] is recommended
