SKU CH-BXQ8-AW9SE

Converts a USB-C PD charger to power laptops with a 7.4x5.0mm DC port by negotiating 18-20V output

  • Converts USB-C PD chargers to 18-20V laptop power
  • Built-in PD trigger chip negotiates voltage automatically
  • Multi-layer protection prevents overload and short-circuit damage
  • Lightweight design replaces bulky original adapter for travel
  • Plug-and-play charging only, no data transfer supported

USB-C to 7.4x5.0mm DC conversion

This cable connects a USB-C PD charger to a laptop that uses a 7.4x5.0mm barrel charging port. It is aimed at owners of compatible notebooks who want to replace a bulky original power brick with a lighter travel option. The built-in trigger chip handles the handshake with the charger so the correct voltage is delivered automatically. Data transfer is not supported.

Replaces a proprietary laptop power adapter

It substitutes the manufacturer’s AC adapter when you already carry a USB-C PD power supply that can output 18 or 20 volts. The switch is worthwhile if your charger meets the laptop’s voltage and current needs and you want a single charger for multiple devices. It will not work with non-PD USB-C sources or laptops that require a different barrel size.

Sustained charging with protection circuits

Integrated overvoltage, overcurrent, short-circuit and overheat safeguards keep the connection stable during long charging sessions. The cable maintains the negotiated voltage continuously rather than only in brief bursts. Its compact form factor stays cool enough for daily commuting and office use without adding bulk to a bag.

Questions about this item

What size DC barrel connector does this cable plug into?

The cable ends in a 7.4x5.0mm round DC connector that fits laptops using that exact barrel size.

How do I set up the PD trigger chip to get 18V-20V from my charger?

Plug a USB-C PD charger into the female port; the built-in chip automatically negotiates 18V-20V output with no buttons or software required.

Will the integrated protection circuit ever need replacement?

The overvoltage, overcurrent, short-circuit and overheat protection is built into the cable and does not require user replacement.
