Charge Adapter for 140 W USB-C Devices

The LORDWORLD adapter converts a DC 4.5x3.0 mm barrel input into a USB-C PD output so owners of 135 W or 140 W chargers can power compatible laptops, tablets and phones. It is intended for users who already possess a high-wattage barrel-tip supply and need a Type-C connection without replacing the original brick.

Thermals, Noise and Power Draw

The unit draws up to 140 W from an 18 V to 20 V DC source and delivers a maximum of 140 W through selectable PDO profiles of 5 V 2 A, 9 V 3 A, 15 V 2 A, 20 V 3.25 A, 20 V 5 A and 20 V 7 A. No active cooling is present, so operation is silent and thermal load depends entirely on the attached charger and cable.

DC 4.5x3.0 mm Barrel Compatibility

This adapter only works with power supplies that provide a 4.5x3.0 mm centre-positive tip at 18 V to 20 V and support the required current for the desired output profile. Buyers whose chargers use a different barrel size, voltage range or polarity cannot use this product.

Questions about this item

How do I connect the DC 4.5x3.0mm plug from my 135W or 140W charger to this adapter?

Insert the charger's DC 4.5x3.0mm barrel tip firmly into the adapter's matching input jack; the step people miss is confirming the charger supplies 18V-20V before powering on.

Will the built-in PD emulator trigger need replacement after extended use?

The trigger is a solid-state circuit inside the adapter with no moving parts, so it does not wear out or require scheduled replacement.

What thermal or power limit appears first when running a 140W load continuously?

The adapter is rated for 140W maximum output; sustained loads at that level will hit the 140W ceiling before any other limit.
