Small black USB-C female to 7.4x5.0mm barrel adapter

SMUGDESK

SMUGDESK USB-C Female to 7.4x5.0mm DC Adapter 100W

SKU CH-09Y5-62AQR

Converts a USB-C PD charger up to 100W to a 7.4x5.0mm barrel jack for compatible laptops

  • 100W PD fast charging powers compatible laptops
  • 4mm x 5.0mm barrel plug fits legacy DC ports
  • Smart PD chip auto-negotiates voltage for stable output
  • Replaces bulky original adapters with portable USB-C chargers
  • Compact lightweight design fits easily in bags for travel

Purpose and audience

The SMUGDESK adapter converts a USB-C Power Delivery source into a 7.4x5.0mm barrel jack for laptops that still use this classic connector. It lets travellers and remote workers leave the original bulky brick at home and charge from a compact PD charger instead.

Capacity and headroom

The converter supports up to 100W of negotiated power, sufficient for most daily office work, study sessions and light creative tasks on compatible machines. It will run out of headroom if the laptop demands more than the attached PD charger can supply or if the device exceeds the 100W ceiling.

Practical limits of the interface

The adapter only functions with USB-C PD power adapters; it cannot draw power from standard USB-C ports that lack Power Delivery negotiation. Buyers must verify their laptop uses the exact 7.4mm outer and 5.0mm inner diameter barrel size, otherwise the plug will not seat securely.

Questions about this item

Will this 7.4x5.0mm barrel adapter work with the USB-C PD charger I already own?

Yes, the built-in PD trigger chip automatically negotiates voltage with any USB-C PD power supply up to 100W, so your existing charger will deliver stable power to the laptop.

How can I verify the adapter is delivering the correct voltage after I plug it in?

The smart PD chip handles negotiation silently; you will know it is working when the laptop charges normally without intermittent power cuts or loose-connection warnings.

Does the package include a USB-C PD charger or only the barrel adapter itself?

Only the USB-C female to 7.4x5.0mm male barrel adapter is supplied; a compatible USB-C PD charger must be purchased separately.
