By delving into the differences between these USB specifications, we can better understand the different types and functions of USB interfaces so that we can choose the PoE to USBC Adapter and connectors that suit our needs. Understanding this information will also help us use and understand USB technology correctly and avoid some common USB misunderstandings.

As technology advances, USB specifications continue to evolve. To this day, the USB specifications most closely related to our lives are USB 3.0, USB 3.1 and USB 3.2. These numbers primarily reflect the data transfer speed of the USB connector. In order to help readers understand different USB specifications more intuitively, we have prepared the following table for reference.

In October 2022, the European Parliament officially approved the "Single Mobile Charging Port" policy. Starting from the end of 2024, electronic products sold in EU member states must be equipped with Type-C ports.The implementation of this policy will bring convenience, savings and environmental protection to consumers. It is obvious that USB USB-C will play an increasingly larger and more important role in our daily lives.

Because of the advantages of the USB 4 specification, future laptops, desktops and other electronic products can achieve multiple functions such as power supply, audio and video transmission, and data transmission through a Type-C port. USB 4 also emphasizes improving data transfer speeds, being compatible with Thunderbolt 3, and providing unified connectivity. Therefore, USB 4 is hailed as the next generation of high-performance USB standard.

Recommendation:

(1)PT-PTC-D-BT: Supports a variety of electronic products, including MacBook, notebooks, tablets, mobile phones and Switch game consoles. The device needs to be used in a wired network environment that supports IEEE802.3bt. It is plug-and-play and requires no configuration. The PoE to USBC Adapter output supports the PD3.0 fast charging protocol, which can provide continuous power supply and power for low-power mobile devices such as mobile phones, game consoles, and tablets. Stable internet connection.

(2) PT-PTC-D-AF PoE to USBC Adapter is designed with a small-volume white plastic casing, which is very convenient because it can be carried around on the desktop or fixed and opened for use. The input and output of the device does not exceed the safe voltage of 57V and does not require electric shock protection. This product has passed EU CE certification. The device needs to be used in a wired network environment that supports IEEE802.3af. It is plug-and-play and requires no configuration. The output supports the PD2.0 fast charging protocol and can be used for low-power mobile devices such as mobile phones, game consoles, and tablet computers.
