Compatible Devices

This cable connects a USB-C power source to laptops, tablets and phones that use a 4.5x3.0mm DC barrel jack. It is rated for up to 65W and negotiates 5V at 2A, 9V at 3A or 20V at 3.25A depending on the charger. Buyers who need a different barrel size or a higher wattage must look elsewhere.

Supported Protocols

The adapter handles USB Power Delivery plus QC2.0, QC3.0, DCP, PE+1.1, PE2.0, FCP, AFC, SFCP and SCP so a wide range of chargers can be used. Each protocol enables the correct voltage step for the attached device. Users with proprietary charging schemes not listed here will not benefit.

Installation Notes

Plug the USB-C end into a PD charger that can supply 15V to 20V, then insert the barrel jack into the device. Verify the device’s required voltage and current before connecting to avoid damage. No drivers or software are involved, but mismatched voltage will cause immediate failure.

Questions about this item

How often will the USB-C connector or the 4.5x3.0mm DC jack need to be replaced with daily plugging?

Both connectors are rated for thousands of insertion cycles; under normal daily use they typically last several years before any wear appears.

What stops the cable from delivering its full 65 W during a long charging session?

The 20 V / 3.25 A limit is the first ceiling; if the source cannot sustain that profile the cable simply negotiates a lower PD voltage such as 15 V or 9 V.

Does the cable get hot or draw extra power when left plugged in all day?

The copper conductors run cool at the rated 65 W load, and the cable draws no measurable power when the attached device is fully charged or disconnected.
