# DUG7391 140W GaN Charger Dock

The DUG7391 is a compact GaN charger dock for USB-C laptops that need high power at the desk. A built-in 140W USB-C PD 3.1 supply charges the laptop directly from AC power, while HDMI 2.1 outputs 8K30 or 4K144/4K120 with DSC. It adds Gigabit Ethernet and three 10Gbps USB ports, with thermal protection that lowers output if it overheats.
