Generally, cell phones’ batteries run out of power at the right time, so users are always looking for tools to prevent the device from shutting down and being out of communication.

To understand how optimal it is to charge a cell phone from this port, it is necessary to analyze the many types of chargers currently available and the key differences in their charging capabilities.

With this in mind, many people find it an alternative to charging from vehicles, but most USB ports in cars offer only 0.5 amps, which is a very low distribution power that can start to affect the performance of the devices. This is because cell phones have at least the recommended power to charge without damaging their components.

Also, today, most cell phones that include fast charging may require values ​​between 2 and 3 amps on average, so charging them with a USB cable that supplies 0.5 amps is not enough. Using applications such as Facebook and WhatsApp or making calls can drain the battery faster than charging.

Although some companies are interested in this, including updated versions of the USB port (2.0 or 3.0), it is not uncommon for cars to have a port capable of charging devices.

But why is this happening? This is because cars’ USB ports are not designed to charge cell phones, but are designed for low-consumption devices such as USB memory. Precisely, for this device, 0.5 amps of power is sufficient and more than enough.

On the other hand, it also affects the battery consumption level, taking into account that the vehicle requires more fuel because the user has to charge the cell phone from its battery at the moment of connecting it, however the car is disabled when it becomes significant.

Keep in mind that connecting the charger without the phone will drain the vehicle’s battery, even if it is much slower than the cell phone is connected to.

In turn, if you have no choice but to use the car’s USB port to charge the cell phone, do not worry, once or twice it will not damage the device. However, it is important that this procedure does not become routine.

The best option for recharging a cell phone in a car is to use a cigarette lighter charger, which attaches to the cigarette lighter socket (or cigarette lighter plug).
