Black USB-C male plug to silver DC 3.5mm barrel jack cable, 100cm long

Fervit

Fervit USB-C 5.1K Resistor to DC 3.5*1.3mm Power Cable 100cm

SKU CH-ANMM-RMW0E

Converts a USB-C PD charger into a fixed 5 V, 3 A, 15 W DC 3.5×1.3 mm barrel supply for low-power devices such as dashcams, LED strips, mini lamps and fans

  • Fixed 5 V 15 W output protects low-power devices
  • Built-in 5.1 k resistor enables safe PD handshake
  • 100 cm cable reaches dashcams, lamps and fans
  • DC 3.5 × 1.3 mm barrel fits common small electronics
  • Power-only design avoids data lines and fast-charge protocols

USB-C to DC power cable for low-power devices

This Fervit cable converts a USB-C PD charger into a fixed 5 V 3 A supply with a 5.1 k resistor, delivering up to 15 W through a DC 3.5 * 1.3 mm barrel jack. It is intended for users who need to power small DC accessories from a standard Type-C source without data transfer or fast-charge negotiation.

Thermals noise and power draw

The two-core cable operates at a constant 5 V output with a 3 A current limit, so heat generation stays minimal during typical use with dashcams, LED strips or mini desk lamps. No active cooling or fan is involved, and the cable draws only the power required by the connected device up to the 15 W ceiling.

Build fit and constraints

The 100 cm length gives flexibility for routing power to desk-mounted or vehicle-mounted gear while keeping the Type-C plug at the charger. It requires a USB-C PD charger that can supply 5 V at 3 A and a device with a matching 3.5 * 1.3 mm DC input; it cannot power laptops, high-wattage equipment or any device needing 9 V or higher.

Questions about this item

How do I install the cable and what step do people get wrong?

Plug the Type-C male end into a standard PD charger and the DC 3.5*1.3mm male plug into the device, but users often forget to verify the device needs exactly 5V and that the barrel jack size matches, otherwise burnout can occur.

What maintenance or replacement will this cable need later?

The cable has no moving parts or consumables; inspect the two-core wire and connectors periodically for wear or damage and replace the whole cable if the insulation frays or the plug becomes loose.

What limit shows up first under sustained use?

The built-in 5.1k resistor fixes output at 5V with a 3A ceiling, so the 15W power cap is the first constraint when powering small electronics continuously.
