SMUGDESK USB-C to 5.5×2.1mm PD Power Cable 1.8m 100W 65W

SKU CH-Q6A5-VY4BR

Converts 100W 20V USB-C PD input to 65W 5.5×2.1mm DC output with QC and PD support, 1.8m length, built-in protection

  • 100 W USB-C input powers demanding laptops
  • 65 W steady DC output keeps devices running
  • 5 × 2.1 mm barrel fits most laptop ports
  • QC and PD protocols enable fast charging
  • 8 m cable length gives flexible placement

USB-C PD to 5.5×2.1mm DC Cable

This 1.8 metre cable converts a USB-C Power Delivery input into a standard 5.5×2.1mm barrel output. It accepts up to 100 watts at 20 volts and delivers a steady 65 watt DC supply for compatible laptops. The design targets mobile professionals who want to power barrel-jack notebooks from a single USB-C charger.

Multi-Protocol Support with Built-In Protection

The cable handles both QC and PD fast-charging protocols for broad adapter compatibility. Internal safeguards guard against over-voltage, over-current and short-circuit conditions during daily use. A 1.8 metre length gives enough reach for desk, meeting-room or travel setups without excess slack.

Replaces Bulky Proprietary Bricks

Users can leave the original barrel AC adapter at home and carry only a compact USB-C GaN charger instead. The swap is worthwhile when the charger provides 20 volt PD output and the laptop draws no more than 65 watts. It does not suit devices that require higher wattage or non-standard barrel sizes.

Questions about this item

Does the 5.5×2.1mm barrel jack on this cable fit my laptop power port?

The connector uses the standard 5.5 mm outer diameter and 2.1 mm inner pin size found on many laptop power inputs, so it will fit any device that specifies that exact barrel dimension.

What USB-C charger do I need to get the full 65 W output from this cable?

You need a USB-C power adapter that can supply 20 V at 5 A (100 W) over Power Delivery; the cable negotiates that profile and then delivers a steady 65 W through the DC barrel plug.

Is there a specific orientation or handshake step when plugging this cable in?

Connect the USB-C end to the charger first, wait for the PD handshake to establish 20 V, then insert the barrel plug into the laptop; reversing the order can leave the laptop without the negotiated voltage.
