Small black adapter with 7.4 by 5.0mm barrel plug and USB-C port

SMUGDESK

SMUGDESK 7.4 x 5.0mm DC Jack to USB-C Power Adapter

SKU CH-543H-DA902

A 7.4 x 5.0 mm barrel jack adapter converts DC power to USB-C for charging laptops, phones and tablets

  • Converts 7.4 x 5.0mm barrel power to USB-C charging
  • Works with common HP laptop charger plugs
  • Compact plug design fits travel and office bags
  • Charges USB-C laptops, phones and tablets
  • Reuses existing DC adapters without extra chargers

Purpose and audience

This adapter converts a 7.4 x 5.0mm barrel jack into a USB-C charging port. It lets owners of compatible HP laptop chargers power USB-C laptops, phones and tablets without carrying a second charger.

Compatibility check

Verify that your DC power supply uses a 7.4 x 5.0mm plug and that its voltage and current ratings match the device you intend to charge. The adapter passes power only and does not support data transfer.

Upgrade context

It replaces a dedicated USB-C charger when you already own a matching barrel-jack supply. The jump is worthwhile if you want to reduce cable count and your existing adapter meets the voltage and current needs of your USB-C gear.

Questions about this item

What comes in the box and do I need any extra cables?

The package contains the 7.4 x 5.0mm DC jack to USB-C adapter only. You must supply a compatible DC power supply with a 7.4mm x 5.0mm barrel plug and a USB-C charging cable for your device.

How do I know if my existing charger works with this adapter?

Check that your DC power supply has a 7.4mm x 5.0mm barrel connector and that its voltage and current output match the requirements of the USB-C device you intend to charge.

Will this adapter deliver the full charging speed my laptop expects over USB-C?

The adapter passes through whatever voltage and current your DC supply provides, so charging speed depends entirely on that supply matching your laptop's USB-C power profile.
