USB Type C is one of the most flexible connections at the moment and is integrated into laptops, mobile phones and all types of devices.

This connection has become the standard for charging, even Apple has changed the legendary Lightning connector for USB-C since the iPhone 15. Very few phones still integrate the micro USB as a charging port and most are old.

The only devices that have a greater variety of connectors are computers, although current models and gaming laptops integrate USB-C as the main connection for charging.

USB Type C handles different power delivery capacities, so the only way to know its power is by consulting the technical data. Type-C ports with Thunderbolt support different types of charging.

The use of USB Type C has spread in recent years thanks to its advantages in connections:

• The connector is symmetrical, so the cable connects easily without risk of breakage.
• The plug is smaller, allowing for flatter, lighter devices.
• Supports charging and transmission of information and video between peripherals with a single cable.
• Supports higher charging speeds than micro USB.

The power supplies of micro USB cables deliver up to 10 watts and Type A cables between 15 and 18 watts. USB-C uses the USB Power Delivery (PD) transmission protocol that allows up to 100 watts.

Some Type-C cables can even reach 240 watts, although at the moment they are still quite a minority.

The standard Power Delivery protocol offers greater flexibility in power delivery. Devices and power supplies adapt to the power of the cable and charge at the speed indicated, as long as it is equal to or less than what they can support.

This is how USB-C charging technology with Power Delivery works
USB-C cables use Power Delivery (USB PD) charging technology to reach levels between 5 to 48 volts and currents of 3 to 5 amps. The charging speed will depend on the power source, cable and device and will be between 10 and 240 watts.

Mobile phones in recent years usually use speeds around 30 watts, while laptops work at 45, 60, 65 or 100 watts.

The voltage is agreed between the power supply and the consumer, before starting charging.

Manufacturers want to ensure that a USB-C allows you to charge any device at maximum performance, even if the power supply does not meet their requirements.
