20 cm USB4 cable with LED power meter

This 20 cm cable carries USB4 data at up to 20 Gbps and delivers up to 100 W of power. An integrated LED display shows voltage, current and wattage in real time. It also supports video output up to 8K at 60 Hz when the host and monitor both support DP Alternate Mode.

Suits users who want a short.

The 20 cm length limits placement flexibility, so it is not ideal for setups that need a longer reach. Buyers whose devices lack USB4 or DP Alternate Mode will not gain the stated video or speed benefits.

20 Gbps USB4 data rate

This single figure determines whether the cable can handle the bandwidth needed for 8K video, fast external storage or high-throughput docking. If the connected hardware operates at a lower rate, the cable will still work but at that lower speed.

Questions about this item

What clearance does the 20 cm cable need for the LED display housing?

The LED display sits in a small housing on the cable; allow a few millimetres of extra space around the connector so the screen is not pressed against a port or chassis.

Which step is most often missed when connecting this USB4 cable for 8K video?

The monitor's USB-C port must support DP Alternate Mode; without that setting enabled in the display menu the cable will carry power and data but no 8K@60Hz signal.

When should the LED voltage and current readout be checked to confirm the cable is still delivering 100 W?

Verify the display shows 20 V and 5 A while the laptop is under load; a sustained drop below those values means the cable or power source should be replaced.
