LORDWORLD USB-C 140W Adapter

This adapter converts a DC 7.4×5.0 mm barrel input into a USB-C Power Delivery output. It accepts 18 V to 20 V at up to 140 W and supplies selectable voltages from 5 V to 20 V. The built-in PD trigger chip negotiates the correct power profile automatically. It is intended for users who need to power USB-C laptops, tablets or phones from an existing barrel-type charger.

Suitable for owners of 135 W

The unit works with 65 W, 100 W and 140 W USB-C devices that support the listed voltage and current steps. It is not for buyers whose source charger delivers less than 18 V or whose device requires a voltage or current combination not shown in the output table. Users without a compatible barrel-input power supply should look at alternative charging methods.

7.4×5.0 mm DC input connector

The barrel jack size is the single physical constraint that decides compatibility. Only chargers fitted with a 7.4 mm outer diameter and 5.0 mm inner diameter plug will seat correctly. Verify this dimension on your existing power supply before purchase.

Questions about this item

How can I confirm the adapter is delivering the correct voltage after connecting it?

The adapter negotiates 5V, 9V, 15V or 20V output via its built-in PD emulator trigger; check your device's charging indicator or a USB-C meter to see the active voltage.

What comes in the box and what must I supply separately?

The package includes the DC 7.4×5.0 mm to USB-C adapter only; you must provide a 135W or 140W DC charger and a USB-C cable rated for the desired power level.

Which charger wattage should I pair with this adapter for a 140W laptop?

Use a 140W DC 18V–20V charger; a 135W unit will limit output below the adapter's 140W maximum and may not sustain full laptop performance.
