Power Adapter for 18.5 V to 20 V Devices

This compact adapter accepts a USB Power Delivery source and provides a 5.5 mm by 1.0 mm male barrel connector. It is intended for users who need to power or charge equipment that requires 18.5 V to 20 V from a PD charger or power bank.

Automatic Voltage Selection Built In

The adapter negotiates the correct output voltage with the PD source, removing the need for manual switching. Its plug-and-play design means no drivers or configuration are required, and the small 4.7 cm by 1.3 cm housing adds minimal bulk to a travel kit.

Limited to PD Sources Supporting 20 V Output

The connector only functions when the upstream charger or power bank can supply a 20 V PDO; older or lower-power USB-C ports will not activate it. Polarity is fixed to the standard 5.5 mm by 1.0 mm barrel arrangement, so devices with a different pin size or reversed polarity cannot be used.

Questions about this item

Will the 5.5x1.0mm male tip need periodic replacement?

The tip is a fixed metal connector with no moving parts, so it does not require scheduled replacement under normal use.

What stops the adapter from delivering more than 20V during long sessions?

Automatic voltage selection limits output to the 18.5V-20V range, preventing higher voltages from reaching the device.

Does the 4.7x1.3cm body get hot when left plugged in all day?

The small, lightweight housing has no active cooling, but normal operation at rated voltage produces only minimal warmth.
