USB-C PD decoy adapter for notebook charging

This adapter cable converts a USB-C Power Delivery source into a 5.5 mm by 2.5 mm DC barrel output. It supports PD 2.0 and 3.0 as well as QC4 protocols to trigger 18.5 V or 20 V for compatible notebooks. The cable is intended for builders who need to power a laptop from a compact PD charger or power bank.

Passive cable with no active cooling

The unit is a passive cable assembly so it produces no fan noise and adds negligible thermal load to the system. Power draw is determined entirely by the connected PD source and the notebook's requirements up to 20 V. No external power supply or driver installation is needed for operation.

Questions about this item

How do I connect the USB-C plug to trigger the 18.5-20V output for my notebook?

Plug the USB-C end into a PD 2.0 or 3.0 charger that supports QC4 and 18.5-20V profiles; the decoy chip then requests the higher voltage so the DC 5.5×2.5 barrel delivers it to the laptop.

When should I replace this adapter cable if the barrel connector becomes loose?

Replace it when the 5.5×2.5 mm barrel no longer seats firmly or shows intermittent charging, as a worn tip can cause voltage drops that trigger laptop protection circuits.
