In most cases, cigarette lighter circuits use 15 amp fuses, but you can check the fuse box in your vehicle to be sure.
What size fuse do I need for a 12v cigarette lighter?
Individual 12 volt accessories usually have fuses inside their cigarette plugs that are appropriately rated for the particular accessory. The fuse in the plug will normally blow before the 20 amp fuse does. The 20 amp fuse protects the wiring between the battery and the socket in case a short develops there.
How many amps is a cigarette lighter?
The lighter is a metal or plastic cylinder containing a thin flat coil of nichrome metal strip, through which high current (≈10 amperes) passes when the device is activated, usually by pushing it into the socket as though it were a push-button.
What fuse do I need for 12v?
if the device load is known in watts, divide the wattage by voltage-(i.e 100watts divided by 12v = 8.3 amps) -use 10 amp fuse.

How many watts can a 15 amp car fuse handle?
So, 120 Volts times 15 Amps equals 1800 Watts, which would be the maximum wattage a 15 Amp circuit can handle before it trips the breaker or burns out the fuse.
How do I choose the right fuse?
How to Choose the Right Fuse Identify the type of voltage that is being protected. Observe the amperage of the electrical circuit that the fuse will be protecting. Size the fuse to its particular holder. Inspect the fuse for internal element replacement. Use a fuse that has an inspection window.
Can I use a 5 amp fuse instead of a 13 amp?
Yes. The 13amp plug is designed so you set the fuse to the device. So in your case, if the light or radio only needs a 5amp fuse, you use that size.

How much watts can 12V handle?
If you divide 15 by 12 you get 180 Watts, which is your safety zone, because most cars use a 12V system and have a cigarette lighter that has 15 Amps. If you surpass the ceiling of 180 Watt, you will have a blow up.
How many watts is a cigarette charger?
For example, a car cigarette lighter fuse has 15 Amps and most cars use a 12V system, you take 15 and multiply it by 12 and you get 180 Watts which is your safety zone. If you happen to surpass that 180 Watt ceiling, then your fuse will blow.
How many watts can you run on 12V?
A 12 volt 1ah (amp hour) battery is rated to put out 12 watts for 1 hour before it is fully discharged. Or it could do 24 watts for a half hour. A 12 volt 2ah battery can put out 24 watts for 1 hour or 48 watts for half an hour.
