Vszerda UC-066-7450MM-HX 140W adapter

The Vszerda UC-066-7450MM-HX converts a DC barrel jack into a USB-C power source for laptops, tablets and phones. It accepts 18V to 20V input up to 140W and delivers power through a 90-degree angled plug. The compact black unit weighs 0.01 kg and is intended for users who need to power USB-C devices from an existing DC charger. Builders who require a straight connector or a different barrel size cannot use this model.

90-degree angled USB-C plug and PD trigger

The right-angle USB-C connector fits tight spaces around the device port where a straight plug would not clear. An internal 140W 20V 7A PD emulator trigger negotiates the highest available power profile automatically. Supported output steps include 5V/2A, 9V/3A, 15V/2A, 20V/3.25A, 20V/5A and 20V/7A alongside QC2.0 and QC3.0 compatibility. Users without a compatible 135W or 140W DC source will not reach the rated output.

7.4 x 5.0 mm DC input requirement

The adapter only works with a 7.4 mm outer diameter and 5.0 mm inner diameter barrel jack supplying 18V to 20V DC. Mismatched barrel dimensions or voltages outside this range will prevent operation or risk damage. Verify the charger’s rated voltage and current before connecting any device.

Questions about this item

Does the 7.4x5.0mm DC input jack wear out and need replacement after repeated use?

The adapter has no moving parts inside; the DC jack and USB-C plug are solid metal contacts rated for thousands of insertions, so no scheduled replacement is required.

What stops the 140W output first during continuous load — the 20V/7A trigger or the cable?

The built-in 140W PD emulator trigger negotiates 20V at 7A; if the source charger or cable cannot sustain that current, the adapter will step down to the next available PDO such as 20V/5A or 20V/3.25A.

How hot does the black casing get when it runs at 140W all day?

The unit weighs only 0.01 kg and has no fan; under full 140W load it warms to the touch but stays within normal operating limits for a passive DC-to-USB-C converter.
