Power Adapter for USB-C Devices

This adapter converts a DC barrel jack into a USB-C power source for laptops and other USB-C equipment. It accepts an input range of DC 12 to 20.5 volts and delivers up to 100 watts of power. The compact PVC body makes it simple to carry in a bag or pocket. It suits users who need to power USB-C gear from an existing barrel-style supply.

Input Limits and Output Profiles

The unit operates strictly within the stated 12 to 20.5 volt DC input window. USB-C output follows Power Delivery profiles of 5 volts at 1.5 amps, 9 volts at 1.5 amps, and 20 volts at 3.25 amps. Supplying voltage outside the input range will prevent operation. The adapter does not store energy and cannot boost a lower source voltage to reach the higher output levels.

Barrel Connector Fit and Daily Use

The female barrel socket measures 3.5 by 1.35 millimetres, so the mating plug must match those dimensions exactly. A mismatched barrel will not seat securely and can cause intermittent charging. The PVC housing resists casual abrasion but is not rated for rough handling or outdoor exposure. Users should verify their power supply plug size before relying on this adapter for critical work.

Questions about this item

Which voltage range should the DC power supply cover for this 100 W adapter?

The adapter accepts DC input from 12 V to 20.5 V, so any supply within that range will work.

What power levels does the USB-C output actually deliver to a laptop?

The Type-C port negotiates PD profiles of 5 V at 1.5 A, 9 V at 1.5 A and 20 V at 3.25 A, giving up to 100 W.

How does the 3.5 mm by 1.35 mm barrel connector limit what power sources I can use?

Only DC sources fitted with a matching 3.5 × 1.35 mm male plug can connect; the adapter then converts that input to USB-C PD output.
