This is a badge bit (BB) that is part of the PEP curriculum.  Completing this BB is part of getting the sand badge in Electricity.

In this Badge Bit, you will install a 12 volt DC power outlet.

I would like to have a conversation about this BB.

First, there are a lot of images and videos above that I think are not a fit.  But for the conversation, it could all become instantly moot ....


At the ATC this year, I learned that the quality of inverters has become so high and they are now so efficient, that the desire to fiddle with DC has dropped to "very low".  True?

If true, then it seems that we should take this BB out.

Talking to Paul now. It feels like maybe this BB shouldn't be "required." But it's on a list where you can choose other options. And maybe you have a reason to install a 12V DC outlet. So we're going to leave this BB up.

Note that there are currently some issues with the way this BB is described. We want people to install a 12V DC socket, not a 120V socket. So someone can't plug their standard toaster into the thing not set up to deal with a toaster. Fixing this page is on the todo list.
