Rated 5 out of 5 by from Perfect for my needs.Bought a 12 volt to 110vac power inverter that I want to use with either of my two trucks or car. Wanted to make this with quick swap ability because undoing hard wiring would be too much work. These high current plugs work perfectly. Each vehicle has a mating plug hard wired to the battery on a pigtail and left in the engine compartment. I hard wired a mating plug and pigtail to the inverter. Now all I have to do is plug into whichever vehicle I wish to use to power the inverter and have 110vac ac power. Outstanding! Was easy to assemble using 2AWG welding wire. PS - I also made up jumper cables with another plug. Quicker, safer and very effective. Good value.

Can this product be used with 1 AWG wire by trimming some wire and fitting it inside the connector that way?

Asked by: PineOcean
I suppose it could be done that way although I would recommend heat shrink to cover the frayed ends of the cut off strands to prevent any kind of short.

Is this the male side of the connector?

Asked by: Greenfielder
There is not a separate male and female on this. They connect right into each other. essentially the other one would be flipper 180 degrees and they click right together,

Can I use these between my boat battery and my 25hp outboard starter motor?

Hello,I'd like a quick connect application for my electric start Johnson 25hp gas motor. This would connect between the battery and the starter motor (solenoid). I think the current wire is 2AWG or 4AWG. Also, what is the method used to connect the connector to the wires?Thanks,Bob
Asked by: rmjz
Yes these will work very well for that application. These are designed for crimping to the cable.
