You probably know that you can’t connect your laptop directly into your car, but why exactly is that? Your car is producing DC or direct current from the battery and current from the alternator whilst idling, this is usually a 12V DC charge. Your devices are using AC or Alternating Current.
You need to plug your devices into an inverter that converts the direct current coming from your car into alternating current so it can be used to charge up all your electronic gizmos such as laptops, smartphones, fans, and anything else you can think of!
In cars, these inverters can usually be plugged directly into your cigarette lighter, and are incredibly handy if you ever find yourself away from civilization and want a little bit of TV time or a quick peek at those work emails whilst you’re away on holiday.

It also comes with 210 AC outlets which are great for most of your laptops, your Kindles, other electronic devices such as light or fans, basically anything rated under 500 watts.
Bear in mind however that the cigarette lighter plug supports 15A so should only really be used with an electrical load under 150W as anything more can damage your inverter and potentially your device.
There's always an option to hook this bad boy straight up to your 12-volt battery using the included battery clamps whilst running the inverter. This is great if you require a higher electrical load.
As with the other car charging devices, this one comes with an inbuilt cooling fan. This cooling fan automatically turns on when the power reaches over 200-watt which makes sure that the inverter doesn't overheat whilst in use.

Frequently Asked Questions
How Does A Power Inverter Work?
As we said at the beginning of the article, an inverter converts a DC power source (in this case, a 12V car battery) into an AC power source. These inverters do this by rapidly reversing the DC’s polarity to generate a different shaped energy wave (a square wave).
Because many smaller electronic devices such as our laptops, computers, smartphones, and others operate through the use of sine waves, a power inverter uses filters, conductors, and semiconductors along with transistors, diodes, and capacitors to produce a clean sine wave.
The inductor releases this sine way that the technology can register as current and use to power their various devices once it has finished the rectification (conversion) process.
