  • Can a cigarette lighter cause a fuse to short circuit?

  • In some cases, you may find that such an object doesn鈥檛 cause a short circuit all the time, but inserting the cigarette lighter or a 12-volt power adapter causes the fuse to blow immediately.

  • Cell phone chargers are usually designed to work with cigarette lighter sockets without blowing a fuse, but other devices, like cigarette lighter inverters, can easily overload the circuit. Even if your 12-volt device, charger, adapter, or inverter is designed to draw less than 15 amps, it鈥檚 still worth inspecting the plug.
