The ciggie plug melted long ago and I wired up one of those

must say. I can't believe it's still extant.

I agree with robobass, I cannot believe that this retardation is
allowed to flourish in the 21st century.

There are many other connectors competing to become the standard
for
low voltage DC, but none are as easy to insert blindly with one
gloved
hand while driving.

I have hard times imagining that the humanity cannot invent
something
better.

Even I can invent something better that can be inserted with a
gloved
hand in the dark.

Hint, it can be a coaxial twist-lock connector.

If you make it able to deliver 20-30A for a transmitter, inverter,
fridge or faster air compressor, with screw terminals and strain
relief for 12 AWG wire and an internal fuse to protect thinner wire,
it won't be much smaller.

If you don't double or triple the present 120W power limit there's
insufficient reason to change.

I added Anderson cables that I can connect to the battery without
tools, via a wingnut on the Ford's starter solenoid and a spare
underhood fusebox lug on the car. The negative lead is permanently
connected since it isn't a fire hazard.
