  • Real-time voltage, current and power readings on built-in LED display
  • 90° angled DC plug fits tight spaces beside the port

USB-C to 4.0×1.7mm 100W PD adapter

This adapter converts a USB-C Power Delivery source into a 4.0×1.7mm DC barrel output for laptops that still use barrel jacks. It handles up to 100W at 20V/5A when paired with a 100W-rated charger and cable. A built-in LED display shows real-time voltage, current and power. The 90° angled plug fits tight spaces around the port.

Suits laptops with 4.0×1.7mm jack needing USB-C

Ideal for users who want to power or charge a barrel-jack laptop from a high-wattage USB-C brick or power bank. Not for devices that require a different barrel diameter, centre-pin size or voltage outside the 18.5–20.5V range. Buyers without a 100W-capable USB-C charger and cable will not reach the maximum 100W output.

100W 20V/5A maximum output with 90° plug

The adapter delivers up to 100W at 20V/5A provided the source charger and cable are both rated for 100W or higher. It also operates at 65W and supports the 18.5–20.5V window. The 90° connector reduces strain in cramped port areas.

Questions about this item

What USB-C charger and cable do I need to reach the 100W 20V 5A output?

Use a USB-C charger and cable both rated for 100W or higher; the adapter's built-in PD trigger negotiates 20V 5A only when the source supports that level.

Will this adapter work with my existing 65W USB-C charger?

Yes, it also supports 65W and the 18.5V–20.5V range, so a 65W PD source will charge the laptop at its lower negotiated voltage and current.

How can I confirm the adapter is delivering the expected power after I plug it in?

The integrated LED display shows real-time voltage, current and power; verify the numbers match your charger's negotiated profile (for example 20V 5A for 100W).
