If you have bought a car in the last 5 years it is very likely that it has one or two USB A somewhere on the dashboard. These, in addition to connecting USB memory units, also serve to charge the mobile .

Simply connect a compatible cable, connect the mobile and it will start charging. The problem with this system is the power of the load. It is slow , considerably slow. Probably any charger you have at home charges faster than your car .

There is nothing wrong with slow charging the battery, it is even better for its lifespan. The “problem” lies in the purpose of the load on the car. In general, these charges are made when you go to work or shopping, journeys that usually last a few minutes.

The most common car USBs usually charge between 1W and 5W , a charge that can be considered quite slow . If you connect it for 10-15 minutes the result will be poor. It is not a problem with your mobile, but with the power source that gives life to the car’s USB .

Manufacturers cut costs by using poor quality connectors that support the slowest loads on the market. For this reason charging the mobile in the car, with the USB included in the vehicle, is a bad idea . You will only get a few extra minutes of autonomy .

How to charge the mobile fast in the car

If you want to make the most of those minutes of travel to work, our recommendation is that you forget about the USB in your car. They are very good for long trips, to connect a memory unit with music or to use Android Auto or Apple Car Play.

What solutions do you have? A lighter charger with fast charging ! All cars have a cigarette lighter connector and it is very simple and cheap to use it to charge your mobile very quickly. Just buy a fast-charging cigarette lighter charger from Amazon. These are some examples:
