Standard charging cable from 2024 – More than charging: What USB-C cables can do

Berlin (dpa / tmn) – No matter which way you turn it, USB-C plugs always fit. And another advantage: You can charge smartphones and other devices with any USB-C cable – how fast depends primarily on the wattage of the power supply unit.

But beyond charging, USB-C cables have other capabilities defined by the USB Implementers Forum (USB IF): Above all, USB-C cables can also transfer data. If the speed is important here, you have to check what the respective cable can do when you buy it.

Lame wire or fast cable

Because the cheapest strips around five euros only send data relatively slowly, for example with up to 5 or 10 gigabits per second (Gbit/s). If you spend around ten euros on a USB-C cable, you usually also have the option of transferring data much faster – theoretically up to 20 Gbit/s.

All three speeds mentioned now run under USB 3.2. Buyers can only look for the USB logo with the note 5, 10 or 20 (Gpbs). However, the award is anything but uniform and reliable. And of course the achievable data transfer rate always depends on the connected devices. If in doubt, try it out.

If you spend around 20 euros or more, you usually get a cable that meets the latest USB 4 specification, can theoretically transfer data at up to 40 Gbit/s and up to 100 watts of charging or operating current.

That’s enough bandwidth to connect a high-resolution monitor or a USB-C docking station with multiple devices to a notebook, for example. USB 4 is compatible with other display and data interfaces such as DisplayPort or Thunderbolt.
