SKU CH-HTDX-F9SFQ MPN DC5.5x2.1mm

A 1.8m nylon-braided cable delivering up to 140W from a USB-C PD source to a 5.5x2.1mm DC laptop port

  • 8 m cable reaches distant outlets easily
  • 140 W PD input charges laptops at full speed
  • PD 3.1 Emark chip prevents overload and short circuits
  • Nylon braid resists wear from daily bending
  • Five DC tips fit 4.5×3.0, 7.4×5.0, 5.5×2.1, 5.5×2.5 and 6.0×3.7 mm ports

What this cable does

The Vszerda DC5.5x2.1mm cable converts a USB Type-C Power Delivery source into a 5.5 mm × 2.1 mm barrel connector for laptops and devices that use that jack. It is intended for users who want to power or charge compatible hardware from a PD charger or power bank instead of the original brick.

Power limits and connector fit

The cable accepts PD input up to 140 W and is backward compatible with 130 W, 100 W and 65 W sources, while the built‑in Emark decoy chip negotiates the correct voltage and provides overload protection. Only the listed barrel sizes — 4.5 × 3.0 mm, 7.4 × 5.0 mm, 5.5 × 2.1 mm, 5.5 × 2.5 mm and 6.0 × 3.7 mm — are supported, so the device port must match one of these exactly.

The deciding specification

The output plug is a 5.5 mm outer diameter by 2.1 mm inner diameter barrel, and the cable will only deliver power when the PD source can supply the required 20 V profile; buyers whose laptops need a different barrel size or a non‑PD voltage must choose another adapter.

Questions about this item

Which DC connector size matches my laptop among the 5.5x2.1mm, 5.5x2.5mm, 4.5x3.0mm, 7.4x5.0mm and 6.0x3.7mm tips?

Measure your laptop's DC port inner and outer diameter; the cable includes five interchangeable tips covering 5.5x2.1mm, 5.5x2.5mm, 4.5x3.0mm, 7.4x5.0mm and 6.0x3.7mm sizes.

What does the 140W rating mean when I plug this into my laptop?

The cable can deliver up to 140W at 20V 7A from a compatible USB-C PD 3.1 charger, and will negotiate 130W, 100W or 65W if the adapter or laptop requests less power.

How does the USB-C PD 3.1 interface limit the actual charging speed?

The built-in PD 3.1 Emark chip negotiates the highest voltage and current both the charger and laptop support, capping output at the adapter's maximum or the laptop's 20V 7A limit.
