An extension that works in both directions
According to the manufacturer, the cable carries video, data and power both ways, so it does not matter which side the laptop sits on and which side the charger or monitor. Power is capped at 60 W (20 V / 3 A) and data at USB 3.2 Gen 1, which means up to 5 Gbps. An extended link is never faster or more powerful than its weakest part.
