| DC barrel jacks, safe amperage? |

| rsjsouza:
I have some development boards that are rated for 7A on barrel jack connectors, and an old Alienware laptop sees 9A through a slightly larger one. Both have the spring contacts, not the smooth barrel. |

4 pin Molex, 2 for each polarity; that's the common setup for hamradio transceivers which use to take about 20A |
