DC-to-USB-C power adapter

The Fervit adapter converts a 5.5 × 2.1 mm DC barrel jack into a 90-degree USB-C plug, letting you power laptops, tablets and phones from a compatible DC source. It is aimed at users who need to repurpose an existing 135 W or 140 W DC charger for USB-C devices without carrying a separate power brick. The angled connector fits tight spaces around crowded ports where a straight plug would not seat properly. Verify your device's rated voltage and current before connecting to avoid damage.

Thermals noise and power draw

The unit accepts DC input between 18 V and 20 V at up to 140 W and delivers a maximum 140 W output through negotiated USB Power Delivery and Quick Charge 2.0 or 3.0 profiles. Supported output steps include 5 V at 2 A, 9 V at 3 A, 15 V at 2 A, 20 V at 3.25 A, 20 V at 5 A and 20 V at 7 A, matching 65 W, 100 W and 140 W device requirements. A built-in PD emulator trigger handles the handshake so the source supplies the correct voltage. No fan or active cooling is present; the adapter relies on passive heat dissipation during normal operation.

What the angled plug and trigger chip change

The 90-degree USB-C head lets you plug into recessed or side-mounted ports where surrounding plastics or cables block a straight connector, reducing strain on the port and cable. The internal 140 W DC 20 V 7 A PD emulator trigger automates voltage negotiation, so the adapter requests the highest compatible profile without manual switching. This means a single DC charger can serve a 140 W laptop, a 100 W ultraportable and a 65 W tablet in turn, provided each device's specifications fall within the supported output range.

Questions about this item

How do I install the 5.5×2.1 mm DC plug and USB-C connector, and what is the common mistake?

Insert the DC plug fully into the 18-20 V source, then connect the angled USB-C end to the device; the step people miss is confirming the source delivers 20 V before plugging in, otherwise the adapter cannot trigger the 140 W profile.

What maintenance or replacement will this adapter need over time?

No scheduled maintenance is required; replace the unit if the DC jack or USB-C connector becomes loose, shows bent pins, or if the housing cracks from repeated angled insertion.

What limit appears first during sustained 140 W use?

The 20 V 7 A output ceiling is the first hard limit; if the load demands more than 7 A at 20 V the adapter cannot supply it and the device will throttle or stop charging.
