SKU CH-HXXQ-EKVX5

  • Charges laptops via USB-C with 100 W PD trigger

  • Works with QC 2.0 and QC 3.0 chargers
  • Supports 65 W output for compatible devices

Cable purpose and compatibility

This cable converts a USB-C Power Delivery charger into a 5.5 mm DC barrel output for laptops that use a rectangular jack. It contains a built-in 100 W PD trigger that negotiates 20 V at 5 A with the charger. The cable is intended for users who want to power a compatible laptop from a single high-wattage USB-C adapter. It works with ThinkPad X1 and Legion Y7000P models that have the matching DC port.

Who should use it and who should not

Suitable for owners of laptops with a 5.5 mm DC input who already carry a 100 W or 65 W USB-C PD charger supporting QC 2.0, QC 3.0 or USB PD. Not suitable for devices that require a different barrel diameter, a voltage other than 20 V, or a charger below 65 W. Buyers who need simultaneous data transfer or video output should look at a different cable type.

Deciding specification

The cable delivers a fixed 20 V output at up to 5 A, reaching 100 W maximum when paired with a 100 W USB-C PD charger, and also supports 65 W operation with a 65 W charger. The charger used must be rated higher than the laptop’s required input power. Verify the laptop’s DC jack is exactly 5.5 mm before purchasing.

Questions about this item

Does the cable get hot when running at 100W all day?

The cable carries up to 100W at 20V 5A; sustained full load will warm the connectors but the built‑in PD trigger regulates power to stay within USB‑C limits.

What charger do I need to make this cable work?

You must supply a USB‑C charger that delivers at least 65W or 100W with Power Delivery 2.0 or 3.0 so the cable can negotiate 20V output.

Will it charge my older ThinkPad X1 that uses a 5.5 mm barrel jack?

Yes, if the laptop accepts 20V DC through a 5.5 mm jack and its original charger is 65W or less; the cable passes 20V at up to 5A from a compatible PD charger.
