USB-C to DC 5.5×1.7 mm 100W adapter

The Fervit adapter converts a USB-C Power Delivery source into a 5.5 mm by 1.7 mm barrel output for laptops that lack native USB-C charging. It targets owners of barrel-jack notebooks who want to use a single high-power USB-C charger across multiple devices. The unit is plug-and-play with no drivers required.

LED voltage current wattage display

A built-in LED screen shows real-time voltage, current and power so users can verify that the charger is delivering the expected 100 W 20 V 5 A profile. This visibility helps confirm that both the source charger and cable meet the 100 W specification before relying on the connection for critical work. The display draws negligible power and stays readable in typical indoor lighting.

100 W PD trigger and barrel output limits

The adapter contains a fixed 100 W 20 V 5 A PD trigger, so it will only negotiate the 20 V PDO from a compatible source. If the charger or cable is rated below 100 W the output falls back to lower profiles such as 65 W or the 18.5 V to 20.5 V range. Polarity and barrel dimensions are fixed at 5.5 mm outer and 1.7 mm inner, so laptops with different jack sizes cannot be connected.

Questions about this item

Does the LED display itself need any maintenance or replacement over time?

The built-in LED display shows voltage, current and power in real time and has no user-serviceable parts; if it fails the whole adapter would need replacing.

What limits continuous 100 W output during extended use?

The adapter is rated for 20 V at 5 A up to 100 W; sustained output requires a 100 W or higher USB-C charger and cable, otherwise power will be limited to 65 W.

How much heat or noise does the alloy-shelled adapter produce when running all day at full load?

The passive alloy shell dissipates heat silently with no fan; surface temperature will rise under continuous 100 W load but no audible noise is generated.
