DC 3.5×1.35 mm to USB-C PD adapter

This adapter converts a DC 3.5 mm × 1.35 mm barrel jack into a USB Type-C male plug with Power Delivery support. It is intended for laptop users who want to power a USB-C device from an existing DC charger. The built-in PD identification chip negotiates 5 V, 9 V or 20 V output automatically. Input voltage range is 15 V to 20.5 V.

100 W PD output with 20 V 5 A limit

The single specification that decides compatibility is the 100 W maximum output at 20 V and 5 A, with no 12 V or 15 V PD profiles. Your DC source must supply more power than the laptop draws; for example, a 90 W charger can only run a laptop below 90 W. If the source and load are both rated at 90 W the adapter will not function.

Plug-in adapter with barrel-to-C conversion

Installation is a simple plug-in: connect the DC barrel plug to the female input and the USB-C male end to the device. No drivers or configuration are required. The most common issue is using a charger that does not exceed the laptop’s power demand, which prevents the adapter from delivering power. The compact 0.041 kg design makes it easy to carry.

Questions about this item

What does the 100 W rating mean when I plug this adapter into my laptop?

The adapter can pass up to 100 W from a DC 3.5 mm × 1.35 mm source to a USB-C device, provided the source charger is rated higher than the laptop's own power draw.

Which USB Power Delivery voltages does the built-in chip actually negotiate?

The chip negotiates 5 V, 9 V and 20 V only; 12 V and 15 V are not available on the USB-C output.

Will the DC 3.5 mm × 1.35 mm female jack fit my existing charger tip?

Yes, the input is a standard 3.5 mm outer diameter by 1.35 mm inner diameter female barrel connector.
