Qingda takes you to understand the difference between USB and type C

The differences between USB and TypeC are mainly reflected in the following aspects:

1. Interface Shape and Design:

    USB: Traditional USB interfaces (such as USBA, USBB, MicroUSB, MiniUSB) come in various shapes, mostly asymmetrical, requiring attention to orientation during insertion.

    TypeC: USB TypeC is a newer interface standard with a symmetrical oval design, allowing reversible plugin for greater convenience.

2. Size and Portability:

    Traditional USB interfaces (like USBA) are generally larger, suitable for PCs or large devices; MicroUSB is smaller but still requires orientation.

    TypeC is compact, suitable for modern devices like smartphones, tablets, and laptops, with better standardization.

3. Data Transfer Speed:

    USB: Speed depends on the version, e.g., USB 2.0 (up to 480Mbps), USB 3.0 (5Gbps), USB 3.1 Gen 2 (10Gbps).

    TypeC: As an interface shape, it supports multiple protocols (e.g., USB 3.1, USB 3.2, USB 4.0, Thunderbolt 3/4), with speeds up to 40Gbps (USB 4.0 or Thunderbolt 4), though actual speed depends on the device and cable’s supported protocol.

4. Charging Capability:

    Traditional USB (e.g., USBA, MicroUSB) has lower power, typically supporting 5V/2A (10W) or less.

    TypeC supports USB Power Delivery (PD) protocol, with up to 240W (USB PD 3.1), suitable for fast charging of phones, laptops, and more.

5. Compatibility and Functionality:

    USB: Different interfaces (e.g., USBA, MicroUSB) are not compatible with each other, often requiring adapters.

    TypeC: A unified interface, compatible with various devices and functions (e.g., data transfer, charging, video output like DisplayPort or HDMI Alt Mode). A single TypeC cable can serve multiple purposes.

6. Adoption and Prevalence:

    Traditional USB is still Widely used in keyboards, mice, flash drives, etc., but is gradually being replaced by TypeC.

    TypeC has become the mainstream interface for modern devices (e.g., smartphones, laptops), with the EU mandating its use for electronic devices by the end of 2024.

Summary:

 USB is a broad interface standard encompassing various shapes and versions; TypeC is a specific interface type, more modern and powerful.

 TypeC’s advantages include reversible plugin, highspeed transfer, highpower charging, and multifunctionality, making it the industry standard.

 In practice, TypeC performance depends on the cable and device’s supported USB version or protocol.
