Vszerda 65W DC-to-USB-C Adapter

This adapter converts a 4.5 x 3.0 mm DC barrel jack into a USB-C power source, delivering up to 65 W for laptops, tablets and phones. The 90-degree right-angled plug fits tight spaces around crowded ports, making it practical for cramped desk setups or travel bags. It accepts a wide 18–20 V input range from existing power bricks, so users can reuse older chargers instead of buying new USB-C units.

Steady 65W delivery across multiple voltage steps

The adapter negotiates PD and several quick-charge protocols to maintain 5 V/2 A, 9 V/3 A, 12 V/2 A, 15 V/2 A or 20 V/3.25 A under continuous load. Because the output stages are rated for the full 65 W, sustained charging sessions do not throttle back after an initial burst, keeping compatible MacBooks, ultrabooks and tablets at their maximum charge rate throughout the session.

Replaces bulky proprietary bricks for USB-C devices

Users with a working 18–20 V barrel-jack charger can keep that brick and add this adapter instead of purchasing a dedicated USB-C power supply. The upgrade makes sense when the original charger is still reliable but the device has moved to USB-C charging; it is not suited for devices that need more than 65 W or for barrel-jack laptops that cannot accept USB-C input.

Questions about this item

How much heat does the adapter generate when running at 65W all day?

The adapter accepts DC 18-20V input and delivers up to 65W through multiple voltage steps including 20V at 3.25A, so sustained full-load operation will produce noticeable warmth but no active cooling is present.

What must I already own to use this adapter?

You need a DC power source with a 4.5x3.0mm barrel plug supplying 18-20V and a USB-C device that negotiates PD or QC profiles such as 5V/2A, 9V/3A, 12V/2A, 15V/2A or 20V/3.25A.

Will the 90° right-angled plug clear the tight space beside the DC jack on my legacy laptop?

The right-angled design is made for limited clearance around a female DC port, letting the cable run parallel to the chassis instead of sticking straight out.
