Allcigarette lighter sockets are likewise 12v sockets,which way that friend shouldbe maybe to plug in acigarette lighter inverter, cabinet charger, or any other 12v DC accessory into any cigarette lighter socket, in any vehicle, and also have it work just fine.

When a cigarette lighter socket stops working or seems to malfunction, there are a few things that deserve to go wrong:

An obstruction within the socket - This happens most frequently when the cigarette lighter socket is set up vertically into a facility console because that orientation provides it very easy for small items to loss into the socket. Non-conductive obstructions prevent chargers native making contact, if conductive objects prefer coins can blow the circuit.The cigarette lighter socket is blown - This just means that there's no power obtaining to the socket in ~ all. The fuse might be blown, or there can be another problem with the wiring.The charger itself is negative - Chargers perform go bad, for this reason you require to ascendancy this out. The electronic devices inside the charger might be bad, the plug the goes into your an equipment could be back, or the springs in the plug that goes right into the tobacco lighter socket could be worn out.

Check for power and ground at the socket - This needs a check light or a voltmeter. If you have these tools and also know exactly how to usage them, check for strength on the center pin inside the cigarette lighter socket and ground on the inner of the barrel. If girlfriend don't discover power, check the fuses. If friend don't discover power or ground, examine the relations that plug into the tobacco lighter socket.

Try plugging in a different machine - If friend don't have actually a check light or voltmeter, find a various 12V charger or device. It's vital to make sure that the maker actually works, so you may want come borrow something native a girlfriend or family member that they use regularly. If girlfriend plug that in, and also it doesn't work, there most likely isn't power to the socket.

Try plugging in the cigarette lighter - If you still have the cigarette lighter the came with your car, plug that in and activate it by pushing in firmly. If that pops out, and the coils are red hot, there's naught wrong with your socket. If that doesn't warmth up, your socket doesn't have power.

check for foreign Objects

In a instance where nothing friend plug right into a 12v accessory socket works, the an initial thing you'll want to do is check for obstructions within the socket. The easiest means to execute this is come grab a flashlight and also physically look inside the socket.


One that the most common causes of tobacco lighter and 12v accessory socket troubles is as soon as a coin falls into the socket accidentally. This can cause the socket to quick circuit and also blow out the fuse, however it can also prevent accessory plugs from making contact.

When non-metallic objects autumn into a cigarette lighter or 12v accessory socket, you won't finish up through a quick circuit or swollen fuse. However, the foreign object can still stop an accessory plug indigenous making electric contact. That way the circuit will certainly still be warm when girlfriend reach inside to eliminate the instruction, therefore take treatment not come accidentally quick it out.

inspect for power

If over there aren’t any kind of obstructions in the socket, climate you have the right to proceed in among three ways. The most basic is to merely plug in the cigarette lighter if you have it. If the lighter heats up and pops out, climate the socket has power. You can likewise use a test light to check for power, if you have one, or research the fuse panel to view if the cigarette lighter fuse is blown.

If her 12v socket is in reality an accessory socket and not a tobacco lighter socket, then you can"t check it by making use of the cigarette lighter. In the case, you"ll have to use a test light or multimeter come actually check for power.

If the fuse isn’t blown, and the socket has power, then there may be an issue with either the socket or the accessory plug the you room trying to use through it. Cigarette lighter and 12v accessory sockets room designed through somewhat loose tolerance in mind, and the slack is taken up by spring-loaded contacts, but if contact isn’t taking place, then her accessory won’t get power.

handling a Blown cigarette Lighter Fuse

In countless cases, you will discover that the cigarette lighter fuse is blown, which can be the result of a number of different issues. If you discovered a coin in the socket, then the is more than likely the finish of it. If friend didn’t, climate you may have a quick elsewhere, or you may have actually plugged miscellaneous in, prefer a cigarette lighter inverter, that simply draws an ext amperage 보다 the circuit is designed to handle.

Cigarette lighter circuits are regularly fused at 10 or 15A, which no a entirety lot in the grand plan of things. For this reason if your tobacco lighter inverter isn't specifically designed come keep current demands below that level, plugging in any variety of electronics can theoretically blow your fuse and keep the inverter native working.

The easiest way to proceed from there is to change the cigarette lighter or 12v accessory socket fuse and also see what happens. If it blows immediately, you’re taking care of a short somewhere in the circuit. If you plugin the tobacco lighter and the fuse blows, then that is most likely the issue. If every little thing is well initially, however the fuse blows once you plugin the inverter, then the inverter is more than likely the culprit.
