  • USB-C input enables convenient PD power delivery

  • Stable current transmission keeps laptop power steady
  • Plug-and-play connection works instantly without extra drivers

Power Cable for USB-C Laptops

This 1.8 metre cable converts a USB-C power source into a standard 5.5×2.1 mm DC jack for laptops and notebooks. It suits users who need to power barrel-jack devices from a USB-C charger or power bank. The plug-and-play design requires no drivers or software setup.

Build Integration and Flexibility

The 1.8 metre length gives reach between a wall charger or power bank and the laptop on a desk or table. It frees the user from carrying the original bulky AC adapter when a compact USB-C PD supply is already available. No extra converters or cables are needed for the connection.

Upgrade from Proprietary Adapters

It replaces a fixed-cable AC brick for users who want a lighter travel kit centred on a single USB-C power source. The jump is worth it when the USB-C charger delivers sufficient power for the laptop model. Buyers whose devices need a different barrel size or a higher voltage than the source provides cannot use this cable.

Questions about this item

How much current can the 5.5×2.1 mm DC jack deliver continuously?

The cable transmits the current negotiated by the USB-C power source, so sustained output depends on the charger's PD profile rather than the cable itself.

Does the cable or its connectors get warm during all-day laptop charging?

The cable is rated for stable power delivery at 1.8 m length; noticeable warmth would indicate the source or device is drawing more current than the cable's conductors are sized for.

What USB-C charger do I need to power a laptop through this cable?

You need a USB-C Power Delivery charger that can supply the voltage and wattage your laptop requires; the cable simply passes that negotiated power to the 5.5×2.1 mm jack.
