  • How about getting a panel mount female to go with this?

  • the car don't output 12v all time. the output can go to 15v in certain moments.

    • it's worse than that, it may be as low as ~6-7V when cranking, around ~15V with the engine running and load dumps maybe as high as several hundreds volts. A car is the power supply from hell and electronics needs several layers of protecting to be reliable in a car


  • I just bought this. I cannot read the fuse rating, because the top-half of the numbers weren't printed.

    Is it a 10A fuse? (looks like it was trying to say 10A...)

  • Great to have a fairly priced source for these!

  • What's the max current this plug (and/or the included fuse) is rated for?
