What are the differences between type c charger and usb c PD charger?

The differences between a Type-C charger and a USB-C PD (Power Delivery) charger mainly lie in charging protocols, charging speeds, compatibility, and application scenarios.

Charging Protocols

• Type-C Charger: Type-C refers only to the physical interface form factor and does not inherently limit the charging protocol. This means that Type-C chargers can support multiple charging protocols, including but not limited to USB PD, QC (Quick Charge), and others. However, the specific protocols supported depend on the charger's design and the manufacturer's choice.

• USB-C PD Charger: A USB-C PD charger explicitly supports the USB Power Delivery protocol. This is a fast-charging standard developed by the USB Implementers Forum (USB-IF), which allows for higher voltage and current outputs, enabling faster charging speeds.

Charging Speeds

• Type-C Charger: Since Type-C chargers can support multiple charging protocols, their charging speeds may vary depending on the protocol and device compatibility. If a Type-C charger supports the USB PD protocol and the device also supports it, then it can achieve fast charging. However, if either the charger or the device does not support the USB PD protocol, the charging speed may be slower.

• USB-C PD Charger: USB-C PD chargers typically offer faster charging speeds due to their explicit support for the USB PD protocol. They can provide up to 100W of power output and support any combination from 5V to 20V and 0.1A to 5A, which makes them capable of meeting the charging needs of a wider variety of devices.

Compatibility

• Type-C Charger: The Type-C interface has broad compatibility and can connect to multiple devices, including smartphones, tablets, laptops, and more. However, if the charger does not support the charging protocol required by the device, it may result in slower charging speeds or inability to charge.

• USB-C PD Charger: USB-C PD chargers also offer good compatibility, but since they explicitly support the USB PD protocol, they provide a better charging experience when connected to devices that also support this protocol. However, for older devices or those that do not support the USB PD protocol, USB-C PD chargers may not be able to fully leverage their advantages.

Application Scenarios

• Type-C Charger: Type-C chargers are suitable for various scenarios, including charging smartphones, tablets, laptops, and other devices. Due to their support for multiple charging protocols, they can flexibly meet the charging needs of different devices.

• USB-C PD Charger: USB-C PD chargers are more suitable for scenarios requiring fast charging and high-power output. For example, business professionals who frequently travel or commute may benefit from carrying a power bank or charger that supports the USB PD protocol to provide fast and efficient charging for their mobile devices. Additionally, USB-C PD chargers support features such as high-definition video output and audio output, making them useful in more scenarios.

In summary, Type-C chargers and USB-C PD chargers differ in charging protocols, charging speeds, compatibility, and application scenarios. When choosing a charger, users should make decisions based on their device needs and usage scenarios.
