Right-Angle DC-to-USB-C Adapter
The SMUGDESK 90° Right-Angle DC 7.4×5.0mm Female to USB-C Male PD Power Adapter converts a legacy barrel power brick into a USB-C fast-charging source. Its elbow design prevents cable bending and fits tight port gaps on laptops or in vehicles. The adapter supports Power Delivery negotiation at 5V, 9V, 15V and 20V with a peak capacity of 140W. It is built for users who want to reuse an existing 18V-20.5V DC charger for modern PD devices.
Suits owners of 7.4×5.0mm barrel chargers.
This unit suits owners of Dell or HP power bricks that use the 7.4×5.0mm centre-positive connector and output between 18V and 20.5V. It works with 65W, 96W, 100W and 140W PD laptops, tablets and phones. Buyers whose charger uses a different barrel diameter or centre-negative polarity cannot use this adapter. Users needing a straight cable or a higher voltage input range should look at something else.
Check your charger’s output voltage
Before ordering, verify that your existing power supply delivers 18V to 20.5V and uses a 7.4×5.0mm centre-positive plug. Confirm your target device charges via USB-C Power Delivery at 5V, 9V, 15V or 20V. The adapter’s built-in chip auto-negotiates the correct voltage, but the source must stay within the stated input window. No driver installation is required for operation.

Questions about this item
Do I need a specific DC barrel power supply to use this 7.4×5.0mm adapter?
Yes, you must already own a centre-positive 7.4×5.0mm DC power brick that outputs between 18V and 20.5V; the adapter then negotiates 5V, 9V, 15V or 20V up to 140W via its built-in PD trigger chip.
Will my older 65W or 96W Dell or HP barrel charger work through this right-angle converter?
Any legacy 7.4×5.0mm charger delivering 18V–20.5V works; the adapter auto-negotiates the correct PD voltage so a 65W, 96W or 100W brick becomes a USB-C fast-charge source for compatible laptops and phones.
How can I confirm the 90° adapter is delivering the negotiated PD voltage after I plug it in?
Check the connected device’s battery or power settings — it should show active USB-C PD charging at 5V, 9V, 15V or 20V, and the adapter’s nickel-plated pins plus OVP/OCP/SCP/OTP protection keep operation stable without drivers.
