Power adapter for USB-C laptops

The GearMo GM-PDU31CNA is a 50W notebook power adapter that replaces a bulky factory charger. It accepts 100V to 240V AC input and delivers power through a USB-C port with Power Delivery at five voltage levels up to 20V and 3A. The unit also integrates a USB 3.1 Gen1 hub and an HDMI dongle for display output.

Thermals noise and power draw

The compact adapter measures 80mm by 61mm by 26mm and operates silently with no moving parts. Power conversion happens inside the enclosed beige housing while drawing from a standard wall outlet. Normal use sees the brick warm to the touch but well within safe limits for continuous operation.

Build connectors and daily use

A 1.5m AC cord and a 45cm USB-C to USB-C cable are included in the box. Two USB-A ports and one downstream USB-C port provide 5Gbps data and 5V 3A charging for peripherals. The HDMI receptacle supports up to 192kHz audio at 24-bit depth for external monitors or projectors.

Questions about this item

How do I connect the GM-PDU31CNA to my notebook and wall power?

Plug the 1.5m AC cord into a 100/240VAC outlet, then connect the included 45cm USB-C cable from the adapter's upstream USB-C PD port to your notebook's USB-C charging port.

What parts of the GM-PDU31CNA might need replacement after extended use?

The 45cm USB-C to USB-C cable and 1.5m AC power cord are the only detachable components; the adapter body, HDMI receptacle, and USB-A/USB-C hub ports are fixed.

What is the maximum power the GM-PDU31CNA can deliver continuously to my notebook?

The upstream USB-C PD port supplies up to 50W across five voltage levels (5V, 9V, 12V, 15V, 20V) at 3A, which is the sustained output limit.
