Fervit 140W 100W DC Jack 7.4x5.0mm to USB-C 90 Degree Power Adapter

SKU CH-FGV8-4T4D5

Converts a 7.4×5.0 mm DC jack into a 90-degree USB-C plug delivering up to 140W for laptops, tablets and phones

  • Delivers up to 140W for fast laptop charging
  • Built-in PD trigger enables 20V 7A output from DC source
  • 90-degree plug fits tight spaces around ports
  • Accepts 18V–20V DC input from 135W or 140W chargers
  • Compatible with 140W, 100W and 65W USB-C devices

What this adapter does

The Fervit power adapter converts a DC 7.4x5.0 mm barrel input into an angled USB-C output with a built-in 140 W PD trigger. It accepts 18 V to 20 V at up to 140 W and delivers selectable PD voltages from 5 V up to 20 V at 7 A. The 90-degree plug fits tight spaces around the port.

Who it suits and who should look elsewhere

Builders who need to power USB-C laptops, tablets or phones from an existing 135 W or 140 W barrel charger will find this adapter useful. It supports QC 2.0, QC 3.0 and USB PD profiles up to 100 W and 65 W devices. Users whose source charger cannot supply 18 V to 20 V at the required wattage should look elsewhere. Devices that demand a native USB-C PD source without a barrel intermediary are not a match.

Deciding specification: input voltage range

The adapter only operates with a DC input between 18 V and 20 V at up to 140 W. If your power supply delivers a different voltage or lower wattage the adapter will not function. Confirm that your charger meets this exact input window before purchasing.

Questions about this item

How do I connect the 7.4x5.0mm DC jack to my 135W or 140W charger, and which orientation mistake should I avoid?

Insert the 90-degree angled plug straight into the charger's female DC port; the right-angle bend routes the cable sideways so it clears tight rear-I/O spaces, but forcing it upside-down can bend the centre pin.

What part of this adapter is most likely to wear out first with daily plugging and unplugging?

The spring-loaded centre pin inside the 7.4x5.0mm DC jack and the USB-C receptacle's retention tabs see the most mechanical cycles; the internal PD trigger chip is solid-state and does not degrade.

At what power level does the adapter hit its thermal or current ceiling during a long charging session?

The hard limit is 140W (20V/7A) from an 18-20V DC source; sustained loads at that level will warm the trigger circuit, so the 100W or 65W profiles run cooler for extended use.
