does it work at all now, on any socket?
If not, I really do suspect the polarity of your new socket, it should be tip +ve if its reveresed, the circuits in these usb chargers etc dont like it, it tends to kill em

I consider that all cigarette lighter type sockets are dangerous as power outputs.
From an electrician's point of view the contact that is made inside these is barely adequate for any decent current flow for any length of time. I have had a cheapo one burst into flames in a car.
If yours is burning plugs then I would say that the contacts are arcing inside resulting in much higher voltages and temperatures than the unit is designed for.
Since the fire I have only used either the DIN sockets or the marine twist locking type, and changed the plugs on any accessories. More money but cheaper than having the car go up in smoke.

Those particular ones?
grrr, people using speaker connectors for power :violent:
as an aside, these alternative connectors are all well and good, but the majority of the 12V kit I use in my fender has the power supply built into the plug, my phone, tablet, the kids DVD players all do.
I did have a hella in the boot tho (till it broke) for higher powered stuff like the air bed inflator, fuel transfer pump and compressor.

I have summat similar to one of these for high amperage use. Dorman 4 Pole Round 20 Amp Trailer Connector - For 6, 12 or 24 Volt | eBay
2 pole and a locating pin to prevent reversing the connection.

In an auto environment where's the issue in using speakon for power? Speakon is designed to handle upto 50a so is more than capable of handling the low ampage devices most people wish to plug in to a car. It's highly unlikely that anyone would plug a speaker into the socket in the car so I see no issue in using them in practice.
If you want to do it properly and for a similar price you could always go the poweron route...

ok, the actual risk of it in a vehicle is low, I just see too many people using the wrong connectors for the wrong thing.
Power cons are generally regarded at 110/230V do wouldn't use those personally either.
shame there isn't a standard for high(ish) power 12V sockets the cigar socket was never designed for continuous use, although some vehicles do have an accessory socket that seems to be a bit more positive in action than the cigar ones.
I do still quite like the Hella plugs, much better contact area, and the +ve has a grove in it to lock into place.

Because it is designed for 50A AC current, not DC current - there is a world of difference. try sticking 12V 50A Dc through it and see.
Better still wrap a couple of coils around yo hand and then try it. Report back when you leave hospital.

I can understand there being a rating difference for switches - the way the current breaks in AC and DC is different - but not for connectors. And the coils - are you implying the connectors have some significant inductive content?
