Adapter purpose and audience

This adapter converts a DC jack measuring 4.0x1.7mm into a USB-C power input. It suits owners of laptops, tablets or phones that charge through a barrel connector and want to use a USB-C PD source instead.

Angled plug and protocol support

The right-angled 90 degree body lets the connector fit into tight spaces around recessed ports. The device negotiates multiple fast-charge protocols including QC2.0, QC3.0, DCP, PE+1.1, PE2.0, FCP, AFC, SFCP, SCP and USB PD.

Input voltage window and output ceiling

The adapter only accepts a DC input between 18v and 20v, so it cannot be used with lower-voltage barrel supplies. Maximum output is 65W with fixed steps of 5V/2A, 9V/3A, 15V/2A and 20V/3.25A, and the supplier warns that mismatched voltage or current can damage the connected device.

Questions about this item

Will the DC jack or USB-C port on this adapter wear out first?

The adapter is a passive connector with no moving parts, so neither the DC jack nor the USB-C port has a rated wear cycle under normal use.

What limits continuous output when charging a 65 W laptop all day?

The adapter is rated for 65 W maximum output at 20 V / 3.25 A; sustained loads above that will trigger protection or voltage drop.

Does the adapter get hot or draw extra power when left plugged in for hours?

It contains no active electronics beyond the PD negotiation chip, so idle draw is negligible and temperature rise stays low during continuous 65 W delivery.
