Vszerda USB-C to DC 5.5x1.7mm cable

The Vszerda UC-149-5517MM-XY cable connects a USB-C power source to a device with a 5.5x1.7mm DC barrel jack. It carries up to 65W of power using copper conductors. The cable supports PD and multiple fast-charge protocols including QC2.0, QC3.0, FCP, AFC and SCP. It is built for charging laptops, tablets and phones that accept USB-C input.

Suits owners of 65W USB-C laptops needing a barrel

This cable fits users who power a 5.5x1.7mm jack device from a USB-C PD charger rated at 15V or 20V input. It works with MacBooks, ultrabooks, tablets and phones that negotiate 5V, 9V or 20V output profiles. Buyers whose hardware requires a different barrel size, higher wattage or a fixed voltage not listed here should look at another adapter.

65W maximum output with 5.5x1.7mm connector

The single specification that decides compatibility is the 65W maximum output delivered through the 5.5x1.7mm DC plug. The cable accepts 15V to 20V input and provides selectable output at 5V/2A, 9V/3A or 20V/3.25A. Verify your device's rated voltage and current before use to avoid damage.

Questions about this item

Will the 5.5 x 1.7 mm DC jack fit my laptop's power port?

The cable terminates in a 5.5 mm outer diameter, 1.7 mm inner diameter barrel connector. Measure your device's charging port to confirm it matches these dimensions before use.

How do I set the cable to deliver 20 V at 3.25 A for 65 W charging?

Connect the USB-C end to a PD charger that negotiates 20 V output. The cable itself contains no switches; voltage is determined entirely by the power source's PD handshake.

When should I replace this cable to avoid damaging my devices?

Replace it if the barrel plug becomes loose, the USB-C connector wobbles, or the jacket shows exposed copper. Internal conductor fatigue can cause voltage spikes that harm connected equipment.
