140W DC-to-USB-C adapter for high-power laptops

This Fervit adapter converts a 7.9x5.4mm DC barrel input into a USB-C output capable of delivering up to 140W. It accepts an 18V to 20V DC source and uses a built-in PD emulator trigger to negotiate power delivery with compatible laptops, tablets and phones. The 90-degree angled plug eases connection where space around the port is tight.

Sustained output through fixed voltage steps

The adapter supplies power at defined profiles: 5V/2A, 9V/3A, 15V/2A, 20V/3.25A, 20V/5A and 20V/7A, topping out at 140W. Because it relies on a DC 18V-20V input rated for the same wattage, continuous delivery depends on the source charger maintaining that voltage under load without throttling. The internal trigger handles the handshake so the attached device receives a stable contract.

Replaces a proprietary barrel charger

It lets a 135W or 140W DC power brick serve USB-C devices that accept 65W, 100W or 140W PD contracts, removing the need to carry the original barrel cable. The upgrade is worthwhile when the existing charger already meets the 18V-20V input range and the target device negotiates one of the listed voltage steps. Users whose laptops require a different input voltage or a higher current than 7A at 20V will not be served by this adapter.

Questions about this item

Does the 140W adapter generate noticeable heat or fan noise when powering a laptop all day?

The adapter contains no fan and relies on passive cooling; it runs warm under continuous 140W load but stays within normal operating temperature for a sealed power brick.

What existing charger must I already own for this DC jack-to-USB-C adapter to function?

You need a separate 135W or 140W DC power supply that delivers 18–20V into the 7.9×5.4 mm jack; the adapter itself does not plug into mains voltage.

Will the 90-degree angled plug still fit if my older laptop has a recessed DC port surrounded by other connectors?

Yes, the right-angle design is made specifically for tight clearances around crowded port clusters.
