What this adapter does and who needs it

This Vszerda UC-066-4530MM-HX adapter converts a DC barrel jack measuring 4.5x3.0mm into a USB-C power connection. It is built for users who want to run a USB-C laptop, tablet or phone from an existing 135W or 140W DC power supply. The 90-degree angled plug fits tight spaces around the port.

Behaviour under sustained load

The unit accepts 18V to 20V DC input at up to 140W and passes power through a built-in PD emulator trigger. Output profiles include 20V at 7A for the full 140W rating, plus 20V at 5A, 20V at 3.25A, 15V at 2A, 9V at 3A and 5V at 2A. It supports PD and QC2.0/QC3.0 handshakes so the connected device negotiates the correct voltage continuously.

The spec that decides fit

The barrel connector must be exactly 4.5mm outer diameter by 3.0mm inner diameter. If your charger tip differs, the adapter will not seat and cannot deliver power. Buyers who need a different barrel size or a straight plug should look elsewhere.

Questions about this item

Does the adapter get hot when delivering 140W continuously?

The adapter is a passive connector with no active cooling; heat will depend on the source charger and cable quality, so ensure good ventilation around the 4.5x3.0mm DC jack during sustained 140W use.

What charger must I already own to use this adapter?

You need a DC 18V-20V barrel charger rated at 135W or 140W with a 4.5x3.0mm centre-positive plug to supply the adapter's input.

Will this work with my older 65W USB-C laptop?

Yes, the adapter negotiates 5V/2A, 9V/3A, 15V/2A or 20V/3.25A via PD and QC2.0/QC3.0, so a 65W laptop will draw only the power it requests.
