12v connectors
I'm wanting to add plenty of 12V jacks in my camper to power various electronics. I already have some 5V USB ports for direct charging of phones, tablets, game systems, etc. And of course I have a c...

Are you pulling power from a light fixture?
That has trouble written all over it.
Yes, I am. The light is designed for two incandescent bulbs which would draw upwards of 4A combined. I am now using LED panels which draw under 300 mA combined. So I have over 3A of current available (even with both lights on) without ever exceeding what the fixture would draw originally with incandescents. Plus, this 40+ year old camper uses 12 gauge wiring throughout. I bet I could pull 15 A from there if I needed (although the fuse in the bus would blow way before that). Regardless, the most I draw is 1A @ 5V for charging, which is only 5 watts, when the fixture can safely draw 48 watts (4A x 12V).
I've made my electronics as efficient as I possibly can. I have 19 LED arrays in place of all incandescents, use low power mobile devices, and for fixed entertainment use a Raspberry Pi drawing 200 mA for my media player / data server.
