PD 18.5V-20V Adapter

The allentian PD adapter connects compatible laptops to power sources using a 4.0x1.7mm male barrel connector. It handles an input range of 18.5V to 20V and features automatic voltage selection for safe, efficient charging. The unit measures 4.7x1.3cm and comes in a silver grey finish. Its plug-and-play design requires no configuration.

For replacement or spare use

This connector suits owners of laptops that accept a 4.0x1.7mm tip within the 18.5V-20V range and need a durable, lightweight spare or replacement. It is not for users whose devices require a different tip size, voltage range or connector polarity. Buyers needing multi-tip kits or higher wattage support should look elsewhere.

Fits in any laptop bag

The compact 4.7x1.3cm form factor slips into a pocket or cable organiser, freeing space in a carry case. It draws power directly from a compatible PD source so no separate power brick is needed. The adapter works with any charger or power bank that delivers the required voltage over USB-C PD.

Questions about this item

What barrel jack size must my existing USB-C PD charger provide to fit the 4.0x1.7 mm male tip on this adapter?

The adapter accepts a USB-C Power Delivery source capable of 18.5 V to 20 V output; the male barrel tip measures 4.0 mm outer diameter by 1.7 mm inner diameter.

Can I keep using my older 18.5 V barrel charger with this connector on a newer USB-C laptop?

No, the adapter converts USB-C PD input to a 4.0x1.7 mm barrel output; it does not work in reverse from a legacy barrel charger.

How do I confirm the automatic voltage selection is active after plugging in?

The adapter negotiates 18.5 V to 20 V from the PD source automatically; a successful handshake means the connected device receives power without manual switching.
