SKU CH-AZSQ-F92EP

A 3.5 x 1.35 mm barrel-to-USB-C cable delivers up to 65 W from a 15–20 V DC source to laptops, tablets and phones

  • Delivers up to 65 W through USB-C PD
  • Accepts DC input from 15 V to 20 V
  • Compatible with QC 2.0, QC 3.0 and multiple fast-charge protocols
  • Fits 3.5 × 1.35 mm barrel jack for laptop power
  • Supports 5 V, 9 V and 20 V output profiles

Input voltage range

This cable accepts a DC barrel input between 15 V and 20 V and converts it to USB-C Power Delivery. It is intended for users who need to power a USB-C laptop, tablet or phone from an existing 15 V to 20 V DC source. The 3.5 mm by 1.35 mm barrel plug fits compatible power bricks or adapters.

Power delivery headroom

The USB-C output negotiates up to 65 W with profiles of 5 V at 2 A, 9 V at 3 A and 20 V at 3.25 A. Devices that require more than 65 W will not charge at full speed and may fall back to lower power. The cable stops at 20 V input, so sources above that voltage cannot be used.

Supported charging protocols

The converter speaks PD together with QC 2.0, QC 3.0, DCP, PE+ 1.1, PE 2.0, FCP, AFC, SFCP and SCP. This broad protocol support lets the cable charge a wide range of USB-C phones, tablets and 65 W laptops without extra configuration. No software or drivers are included or required.

Questions about this item

Will the 3.5x1.35mm DC jack on this cable fit the power port on my older laptop that uses a 15-20V input?

The cable accepts a DC input of 15-20V through its 3.5x1.35mm jack, so it will connect to any compatible laptop port within that voltage range.

How can I confirm the cable is delivering the correct 20V or 65W output to my device after plugging it in?

Check your device's battery or power settings; it should show a USB PD charge rate of up to 20V at 3.25A, matching the cable's maximum 65W output profile.

Does the package include a USB-C power adapter, or do I need to supply my own 65W PD charger separately?

The box contains only the DC-jack-to-USB-C cable; you must provide a separate USB-C PD charger capable of supplying 15-20V input to the cable's DC jack.
