1. Data Port
First, USB 3.0, which can provide 5Gbps transmission speed, is several times faster than USB 2.0 and is called "USB SuperSpeed" in actual device applications.
Until USB-IF introduced USB 3.1 with 10Gbps transmission speed again, the official name of USB 3.0 was changed to "USB 3.1 Gen 1", and "USB 3.1 Gen 2" was USB 3.1 with 10Gbps transmission speed.
Later, USB 3.2 was born with a transmission speed of 20Gbps, and USB-IF announced a new naming convention. The official name of the existing USB 3.0 and USB 3.1 was changed to USB 3.2, with Gen 1, Gen 2, and Gen 2 × 2. Make a distinction.
Specifically, USB 3.0 is renamed as USB 3.2 Gen 1, USB 3.1 is renamed as USB 3.2 Gen 2, and USB 3.2 that can use two USB Type-C Rx/Tx pins are renamed as USB 3.2 Gen 2 × 2」.
USB 3.2, the transmission speed can be improved to 20Gbps, and the native support for multi-channel, channel-doubling performance advantages are obvious. All data pins up and down are used to double the data speed.
2. PD-in Port
USB-C Power Delivery:
USB-PD, or USB-C Power Delivery, is a new protocol specification that allows faster and more flexible charging. It was developed concurrently with USB Type-C (USB-C), the physical connection, and it is a subset of the new USB 3.1 standards. What this means is that:
The USB-C connector is reversible, so you won't struggle to flip the plug until it fits – exactly like the iPhone's lightning connector.
Devices no longer need a separate USB and power jack, as older computers often have
Devices can charge and discharge through the same port, meaning the power direction is no longer fixed.
And most importantly, devices charge much faster! Without USB-PD, the fastest rate for USB-C would be 15W, but with PD, it can go up to 100W.
How does USB-C Power Delivery Work?
The basic gist of how it works is that two USB-PD-enabled devices negotiate a power contract or a handshake when they're plugged into each other. They discuss how much power the source can support and how much power the device being charged can handle. The standard for USB-C devices without PD is 5V/3A, but the voltage depends on the device and can go as high as 20V/5A (with an EMCA cable). Then they settle on a compatible rate at which both the supply and device support and the charging (or discharging) begins.
It's important to note that not all USB-C ports support USB-PD, nor will all USB-C devices charge with all USB-C chargers.
Please note:
Since Anker's hub needs some power for its operation, the power charged to the device will withhold some power required for its operation.
3. Thunderbolt port
Thunderbolt port:
Thunderbolt connection technology combines PCI Express data transmission technology and DisplayPort display technology to simultaneously transmit data and video signals.
The maximum transmission speed of Thunderbolt can reach 10 Gbit/s.
The maximum transmission speed of Thunderbolt 2 can reach 20 Gbit/s
The maximum transmission speed of Thunderbolt 3 can reach 40 Gbit/s.
The maximum transmission speed of Thunderbolt 4 can reach 40Gbps and supports PD charging of up to 100W.
