100 W USB-C to 3.0 x 1.1 mm 100 W DC Adapter, Male to DC Female 19 V Adapter, USB Type C Male Input to DC 3.0 x 1.1 mm Adapter Male Power Supply Cable Adapter for Samsung Acer Laptop

Works exactly as advertized. Has a bit wonky connection on the USB-C side but this could be down to my power brick.

The adapter consistently fails to maintain its nominal voltage, leading to frequent charging interruptions. This issue persisted across three different USB-C chargers and three separate PCs. Furthermore, the problem occurred with both the 7.4 mm and 4.5 mm diameter plugs I purchased. These results strongly suggest a fundamental design flaw rather than an isolated defect, as the issue is replicated across multiple units and configurations.

Passt perfekt. Konnte damit, in Kombination mit dem passenden USB-C Netzteil vom aktuellen Rechner, ein Samsung Ativ9 Ultrabook kostengünstig wiederbeleben.

20v USB Type C power Adapter with DC 4.0x1.7mm Adapter, Male to DC Female 12V 19V 20V Adapter, USB C to DC 4.0x1.7mm Adapter Adapter made for Lenovo Ideapad Yoga Laptop Series @ ~ £6.50 Yep all worked fine. All I can say it is not cheap. I would want to pay that £6.50 for a pair not just one. Otherwise build quality etc is just fine. Hope that helps

Does exactly what I needed. Now I can charge my laptop from the docking hub without extra cables.
