Re: 12v cigarette lighter fuses [links]

[hritzen]

now a different scenario can come to pass with some loads as some will have large current spikes to start off with. these are the ones that usually take the slow blow fuses and some examples might be a fan or a compressor. more

[kathybrendan962]

for the fast blow type this is still rated for the current, but it will melt a tad faster than the normal fuses giving a tighter time tolerance. that time tolerance is basically the difference between all of them given the same current rating as this is the amount of time before the fuse blows.

the fuses are actually located in the adapters just in case you aren't aware. now the sizing i'll address in generalities and note here that this is usually meant to protect the wires. the fuse is to stop current flow in excess of a wire's current rating. <(corrected by me) there is often a bit of wobble and error on this so the rating is always higher than this current draw to eliminate any false blowing of the fuses. i believe the nec goes 1.25x the current for the rating. here

thanks. Do you know why each of the 3 cell phone charges would have a different size fuse. All made for a cell phone ( as clearly indicated by the male end on the other end of the wire). ( 2 fuses are long 1AL 250V), (one is short 2AL250V amp), (another is long F5AL 250v.) (I have a "Y" connector F10AL 250v) [links]

Note: Before you buy a button, you should check the actual socket. You can do this, for example, by plugging in a charging cable for the navigation system and checking whether it is being charged. If this is the case, it is because of the button and this must be replaced. If the navigation system does not charge, the button is functional and does not need to be replaced. Then there is another reason. [links]

Like many other electrical components of your car, the cigarette lighter has a fuse. You should check this first. Many fuses break after several years of use and must be replaced. However, the exchange is quick and easy and you can do it yourself. more

If you were able to rule out both factors as the cause of the defect, the lighter socket itself may be defective. However, this happens relatively rarely and should therefore be checked in a specialist workshop before you buy a new socket.

You can find out where the fuse is on your vehicle in the operating instructions. As soon as you have found the fuse, you should install a new one. The old one serves as a sample when you buy. Since a backup only costs one or two dollars, this is the first step you should take. here

If the fuse was not the reason for the defect, the button itself can also be the cause. You can safely replace it on all vehicles with an original button from the manufacturer. Depending on the model, the costs are around 20 dollars. [links]

A cigarette lighter is practically installed in every car and also serves as a power source for phone chargers and Co. If the socket does not work, there can be various reasons. We have summarized which these are in this article. [links]

Our boat had a car-type cigarette lighter fitted, but no longer connected or working. I want to get that reinstated, and I am planning to wire it straight from the main battery switch with a separate fuse. I was just wondering what sort of current can be safely drawn from this sort of socket, so that I can size the fuse and wiring correctly.

I think you are suggesting Maplin N48AQ and N49AQ. The plain 4mm sockets N32AP and N35AP would look neater but are not gold plated and only accept 4mm plugs not spade terminals or bare wires. more

Thanks for the comments. The heavy current things I was thinking of were cool box, and possibly a dinghy inflater (I don't have that at the moment). Both these would need to be able to run off the car as well as from the boat on occasion, so the cigarette lighter plug would be convenient. Chargers and things won't draw much current. [links]
