This power adapter connector accepts an input range of 18.5V to 20V and terminates in a 5.5mm by 1.7mm male barrel plug. It is intended for users who need to replace or adapt a laptop or device charger tip. The compact black housing measures 4.7cm by 1.3cm for easy portability.

Check device voltage and barrel dimensions

Verify that your equipment requires a supply within the 18.5V to 20V range before connecting. Confirm the jack on your device matches the 5.5mm outer and 1.7mm inner diameter specification. Polarity must also match the device requirement as the adapter does not convert polarity.

Automatic voltage selection under load

The unit features automatic voltage selection to maintain safe and efficient operation across the supported input range. Plug and play design requires no configuration during sustained use. Small and lightweight construction aids heat dissipation in typical charging scenarios. Durable materials support reliable long-term performance.

Questions about this item

What comes in the box and do I need any extra cables?

The package contains the black PD 18.5V-20V 5.5x1.7mm male adapter connector measuring 4.7x1.3cm. No additional cables are included so you must already have a compatible power source with the matching barrel plug.

How do I know this 5.5x1.7mm version is the right one for my laptop?

Check the original charger tip on your device; it must be a 5.5mm outer diameter and 1.7mm inner diameter barrel connector and the laptop must accept 18.5V to 20V input.

What does the automatic 18.5V-20V selection do when I plug it in?

The adapter detects the voltage required by the connected device and adjusts within the 18.5V to 20V range so the laptop receives the correct level without manual switching.
