USB-C 2.1: charging cable for up to 240 watts presented






With USB-C 2.1, devices can be charged with up to 240 watts. Manufacturer Club3D now has the right cable on offer.

USB-C connections are not only suitable for transferring data to hard drives or USB sticks, they can also send image signals to monitors or charge batteries in connected devices. The USB-C 2.1 standard provides a significant increase here: Instead of a maximum of 100 watts at 20 volts and 5 amps, 240 watts at 48 volts at 5 amps are possible. Manufacturer Club3D has now presented three cables with which the performance limit of the Extended Power Range (EPR) standard can be fully exploited.

240 watts via a USB cable

In addition to power, data and video signals can also be transmitted with two of the cables. The third cable, on the other hand, only offers a data speed of USB 2.0, but is also able to charge devices with up to 240 watts. The appropriate logos should make it clear to buyers quickly what capabilities the respective cables offer.

Matching power supplies are still missing

Dubbed the CAC-1573, the two-meter cable is limited to USB 2.0 for data transfer and cannot transfer video either. The CAC-1575 cable, also two meters long, offers USB 4 Gen 2×2 20 Gbps data transfers and can supply 4K resolution screens at 60 frames per second. Just 1 meter long, the CAC-1576 cable supports USB 4 Gen 3×2 40 Gbps and transmits video signals at 8K resolution and 60 frames per second. However, Club3D does not yet offer suitable power supplies. These are all specified with a maximum of 132 watts. So if you want to charge your gaming laptop via USB-C, you not only need a suitable cable, but also the right power supply unit. Unfortunately, the manufacturer has not yet provided any information on the prices of the three cables or their availability.
