USB-C to DC 5.0x1.0mm 100W Adapter with Display

This Fervit adapter converts a USB-C Power Delivery source into a 5.0x1.0mm DC barrel output for laptops. An integrated LED screen shows live voltage, current and wattage so you can monitor the charge. It supports PD and QC 2.0/3.0 protocols with a built-in 100W trigger. The alloy shell protects the contacts during transport.

Suits 20V DC laptops with 5.0mm jacks.

The adapter delivers a fixed 20V at up to 5A, reaching 100W when paired with a 100W-capable USB-C charger and cable. It also works with 65W sources in the 18.5V to 20.5V range. Buyers whose devices need a different barrel diameter or a voltage outside this window must choose another solution.

5.0x1.0mm DC barrel plug and 100W PD trigger

The output connector measures 5.0mm outer diameter with a 1.0mm centre pin, a common size for many laptop power ports. The internal PD emulator requests 20V/5A from the USB-C charger, enabling the maximum 100W rating. Verify your laptop's jack dimensions and voltage requirement before ordering.

Questions about this item

What DC barrel jack size does the 5.0x1.0mm male plug on this Fervit adapter fit?

The adapter ends in a DC male plug measuring 5.0 mm outer diameter by 1.0 mm inner diameter; confirm your laptop's DC jack matches those dimensions before buying.

How do I connect the adapter so the LED display shows voltage, current and power, and what is the step users often miss?

Plug a USB-C PD charger rated at 100 W or higher into the Type-C male end, then insert the 5.0x1.0 mm DC male plug into the laptop; the display activates only when the charger and cable both support 100 W PD.

When will the alloy-shelled adapter need replacement if the LED display stops reading correctly?

The unit has no user-serviceable parts; if the LED display fails or the DC plug becomes loose, replace the entire adapter.
