140W DC-to-USB-C angled adapter

The Vszerda UC-066-5521MM-HX converts a 5.5x2.1mm DC barrel input into a 90-degree USB-C plug. It accepts 18-20V DC at up to 140W and passes power through a built-in PD emulator trigger. The black adapter weighs 0.01 kg and supports output profiles of 5V/2A, 9V/3A, 15V/2A, 20V/3.25A, 20V/5A and 20V/7A.

Suits users with tight port clearance needing 140W

The right-angle USB-C head fits where straight plugs cannot, making it useful for laptops, tablets or phones charged from a 135W or 140W DC source. It is not for devices that require more than 140W input, nor for barrels other than 5.5x2.1mm. Buyers who need a straight connector or a different barrel size should look elsewhere.

Fits between a 135W/140W DC charger

Plug the adapter into the charger's DC jack, then connect the angled USB-C tip to the device. The PD trigger negotiates 65W, 100W or 140W automatically. It frees up space around crowded ports and removes the need for a separate USB-C power brick when a compatible DC supply is already available.

Questions about this item

What DC power source with a 5.5x2.1mm jack do I need to supply 18 to 20 volts at up to 140 watts?

A compatible 135W or 140W barrel-jack charger that delivers 18–20 V DC and can provide up to 140 W.

Will the adapter negotiate 65 W or 100 W profiles with my older USB-C laptop that only supports those levels?

Yes, the built-in PD trigger offers 5 V/2 A, 9 V/3 A, 15 V/2 A, 20 V/3.25 A, 20 V/5 A and 20 V/7 A, so 65 W and 100 W devices will settle on their highest matching profile.

How can I confirm the adapter is delivering the expected 20 V / 7 A (140 W) to my device after I plug it in?

Check the laptop or phone’s battery settings or a USB-C power meter; it should report 20 V and up to 7 A when the source charger and cable both support 140 W.
