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.
