The midtier offering brings USB4 20Gbps data transfer and up to 4K/60Hz video, while the presumably cheapest model supports the 240W power delivery, but the data-transfer capabilities are largely reduced, all the way down to USB 2.0 and 480Mbps. The remaining two models, CAC-1575 and CAC-1573, offer lower specifications. It can also provide video through DisplayPort alt mode at a maximum quality of 8K 60Hz. This is done through the Thunderbolt 3 protocol. The three cables vary in their specifications and capabilities, and only the top cable (CAC-1576) can support a 240W peak wattage (48 volts and 5 amps) while maintaining the full USB4 40Gbps data-transfer rate. Club 3D changes that by introducing three new USB-C cables, each with 240W power delivery.

The new spec brought the power delivery from 100W up to 240W, but up until now, such cables haven’t made it to market. This should slowly begin to change after the introduction of the updated USB Type-C 2.1 specification released last year by the USB Implementers Forum (USB-IF). USB Type-C cables have been gaining in popularity consistently over the past few years, and the only thing that held them back was their relatively low power delivery. Such a power draw means that you should be able to charge most laptops with the new 240W USB-C cable, marking a huge change from the current maximum capabilities of this technology. The first USB Type-C cables capable of providing huge amounts of power are here: Small retailer Club 3D launched three new cables that can each deliver up to 240 watts of power.
