Is there a device that connects to cars cigarette lighter you could plug an electrical chord into?

Yes, there are devices called power inverters that connect to a car's cigarette lighter and allow you to plug in electrical cords. These devices convert the car's DC power into AC power, which is what most electrical devices use.

Power inverters come in a variety of sizes and wattages, so you can choose one that is appropriate for your needs. Some inverters are also equipped with USB ports, so you can charge multiple devices at once.

When using a power inverter, it is important to make sure that it is not overloaded. The total wattage of the devices you plug in should not exceed the wattage rating of the inverter. If the inverter is overloaded, it could overheat and damage your devices.

Power inverters are a convenient way to power electrical devices in your car. They are especially useful for long road trips or camping trips, where you may not have access to an electrical outlet.
