This item is great for hooking up power anywhere you have a 12 or 24 volt battery source!!👍You can use your vacuum are air pump are charge your phone our laptop!! 🙌. to have an extra outlet on a vehicle that don't have an outlet!! I have the answer?!👌 Just get a 10 or 12 gauge wire!!😀 👉(Electrical!!)👈 *NO Speaker Wire!!* Positive and Negative 6 to 8 Foot long! Put the Red Positive to one side 👉( you will need about 20AWP inline fuse!!👈 on the positive wire!👌 and the Black Negative to the other side!! Then hook one end of it, to the cigarette accessory socket! and the other end to your battery source or to the fuses!!(Hot!!) And the other one to a good (Ground!!) the cigarette accessories socket has a (+ & -) sign on it!👍. You can use or purchase any color of wire you want to!! But I prefer-(BLACK and RED!) *Black is for negative!(-)*an*RED is for Positive!(+)*
