Right-angle DC-to-USB-C PD adapter

This compact adapter converts a standard DC 5.5×2.5mm barrel power supply into a USB-C Power Delivery source. It supports up to 140W peak output and automatically negotiates 5V, 9V, 15V or 20V profiles for compatible laptops and smartphones. The 90° elbow design prevents cable strain in tight spaces. Built-in protection circuits guard against over-voltage, over-current, short-circuit and over-temperature events.

Replaces carrying a dedicated USB-C charger

Instead of packing a separate GaN charger, you can reuse an existing 15V-20.5V DC brick to fast-charge PD devices rated at 65W, 96W or 100W. The jump is worthwhile when you already own a suitable DC adapter and want a lighter travel kit. It does not suit buyers who need more than 140W peak power or who lack a compatible DC source entirely.

Check your DC brick voltage and polarity

Verify the existing power supply outputs between 15V and 20.5V with centre-positive 5.5×2.5mm polarity before connecting. Confirm the target device accepts USB-C PD charging at the required wattage. The adapter cannot step up voltage from lower DC inputs or work with barrel sizes other than 5.5×2.5mm.

Questions about this item

Will the 90° right-angle DC 5.5×2.5mm plug clear a tight laptop port?

The right-angle elbow design avoids cable bending and port extrusion, making it suitable for narrow gap ports on laptops and compact device layouts.

Does the adapter need any driver or software to negotiate 140W PD power?

It is plug-and-play with a built-in intelligent PD negotiation chip that auto-matches 5V, 9V, 15V and 20V multi-stage PD voltage without extra drivers.

What DC input voltage range must my existing power brick supply for this adapter to work?

The adapter accepts a wide DC input range of 15V to 20.5V from your existing barrel power supply.
