USB-C to DC 4.0×1.3mm adapter

This Fervit adapter converts a USB-C Power Delivery source into a 4.0×1.3mm barrel jack for laptops. It targets users who want to power a compatible DC-input notebook from a modern USB-C charger. The built-in LED display shows voltage, current and power in real time. Buyers needing a different barrel size or a tip for a non-laptop device cannot use this model.

100W maximum output with 65W fallback

The adapter delivers up to 100W at 20V and 5A when the charger and cable also support 100W. It also works with 65W sources and accepts an input range of 18.5V to 20.5V. If the USB-C supply is below 100W the output drops accordingly, so full 100W headroom is only available with matching hardware. Laptops requiring more than 100W or a fixed voltage outside the 18.5V–20.5V window will not charge.

Real-time wattage display and alloy shell

The LED screen makes charging status visible by reporting live voltage, current and wattage figures. A compact alloy housing protects the connectors and aids heat dissipation during sustained loads. No software or drivers are required; the unit is fully plug-and-play. Users who need cable management clips, a carrying pouch or configurable voltage profiles will not find them included.

Questions about this item

Will this adapter work with my existing 65 W USB-C charger and a laptop that needs a 4.0×1.3 mm barrel jack?

Yes, the adapter also supports 65 W and an output range of 18.5 V to 20.5 V, so a 65 W charger will power compatible laptops through the DC male plug.

How can I verify the adapter is delivering the correct power after I plug everything in?

The built-in LED display shows real-time voltage, current and wattage, letting you confirm the laptop is receiving the expected 20 V 5 A or lower values.

What comes in the box and do I need to buy a USB-C cable or charger separately?

Only the adapter itself is included; a USB-C charger rated at 100 W or higher and a matching USB-C cable must be purchased separately to achieve full 100 W output.
