Thunderbolt 4 products enable you to best access the high performance capabilities of a Mac, high-end iPad or PC through external devices such as data storage and docking stations, whilst genuine Thunderbolt cables make the connection between the device and a your computer or iPad Pro.
Normally you have different cables and products to perform specific tasks. The Thunderbolt port on your Mac, PC or iPad can combine several tasks.
You might connect a high-end monitor to your computer. One out port might provide power to one of your devices. Another port might transfer data from a device to your computer or iPad.
Thunderbolt 4 can combine all of these functions. It will deliver up to 40Gbps data transfer, outputs to 2 x 4K or a single 8K monitor, plus it can deliver power to compatible devices. This might include providing power to your Thunderbolt enabled MacBook or other laptop.
Thunderbolt 4 ports provide a bidirectional 40Gbps data transfer. This means that data can be moved to and from your Thunderbolt external SSD drive. There's an added bonus as you can daisy-chain up to 5 Thunderbolt 4 devices without any loss of performance.
Unlike many other port standards, Thunderbolt 4 is essentially backward compatible. This includes Thunderbolt 3, and with adapters Thunderbolt 1 and Thunderbolt 2, USB, DisplayPort, and PCle. Provided you can use or adapt to a USB-C styled connector, Thunderbolt 4 will talk to your device. If you have an older USB-C accessory such as a keyboard it will plug into a Thunderbolt 4 port and work without problems. You can even charge your phone from a Thunderbolt 4 port but we do recommend a quality Thunderbolt cable or a 100w rated USB-C cable.
You can use an adapter to connect Thunderbolt 4 to a 10 Gigabit Ethernet network or simply use a Thunderbolt cable to connect two computers as a peer-to-peer network. This allows the transfer of large amounts of data from one computer to another, such as when you are setting up a new computer.
Unlike USB-C, Thunderbolt 4 allows you to increase the number of devices you can connect to your Mac, iPad, laptop or PC with a Thunderbolt 4 dock. The more Thunderbolt and USB-C ports your dock offers, the more devices and products you can connect. Typically these Thunderbolt 4 docks will connect to AC power.
Thunderbolt 4 has also enabled us to replace almost all of our older USB-C cables with genuine Thunderbolt cables. Whilst the quality is second to none, using these cables will always offer the highest data throughput or power, no matter what device or product we connect.
Both HomeKit Australia GaN AC chargers and Thunderbolt cables employ "smart" technology to ensure only the exact power or throughout requested is delivered. At present we don't recommend using Thunderbolt cables longer than 1.8 metres but this will increase in future Thunderbolt releases.
