What this adapter does

The LORDWORLD 90° DC 5.5×2.1mm to USB-C 140W Adapter converts a barrel jack input into a USB-C Power Delivery output. It accepts 18V to 20V DC at up to 140W and delivers power through negotiated profiles including 5V/2A, 9V/3A, 15V/2A, 20V/3.25A, 20V/5A and 20V/7A. It is intended for users who need to power USB-C laptops, tablets or phones from an existing DC source such as a 135W or 140W charger. The right-angled plug helps where straight connectors cannot fit.

Build and connector layout

The adapter body houses a built-in 140W DC 20V 7A PD emulator trigger that handles the handshake with the attached device. A 90-degree DC jack accepts the 5.5mm by 2.1mm centre-positive barrel from the source supply. The USB-C receptacle supports Power Delivery along with QC 2.0 and QC 3.0 quick-charge protocols. The angled form factor reduces strain on the source port and keeps the cable run tidy in tight spaces behind desks or inside bags.

Check before you buy

Verify that your DC power supply outputs between 18V and 20V and can deliver the wattage your target device requires up to 140W. Confirm the barrel connector on your supply matches the 5.5mm outer and 2.1mm inner dimensions with centre-positive polarity. Ensure the laptop, tablet or phone you intend to charge accepts USB-C PD input at one of the listed voltage and current steps. Using a mismatched voltage or an undersized supply can damage the connected equipment.
