FANTEC

FANTEC USB-C to DC 5.5×2.1 mm 12 V 3.3 ft cable

SKU CH-HW6V-DG9CN

Converts USB-C PD 20 V input to 12 V 3 A output via 5.5 × 2.1 mm DC plug for routers, cameras and monitors

  • Battery typeAC Adapters
  • Converts PD chargers to 12 V DC with built-in smart chip
  • Delivers up to 12 V 3 A max output for 5.5 × 2.1 mm devices
  • Requires a PD source supporting 20 V output to operate
  • Aluminium alloy shell with 4.5 mm cable and reinforced tails for durability
  • 3 ft male-to-male cable powers routers, cameras, speakers, monitors and LED strips

What this cable does

The FANTEC USB-C to DC 5.5×2.1 mm cable converts a 20 V Power Delivery source into a regulated 12 V output. It delivers up to 100 W from the PD charger while the DC side is rated for 12 V at 3 A maximum. The 3.3 ft cable has male USB-C and male 5.5×2.1 mm barrel connectors.

Who it suits and who should look elsewhere

It suits users who need to power 12 V devices with a 5.5×2.1 mm jack from a PD charger or power bank that supplies 20 V. It does not suit devices that require a voltage other than 12 V or a barrel size different from 5.5×2.1 mm. Buyers without a 20 V PD source cannot use this cable.

The deciding specification

The cable only works when the PD charger or power bank explicitly provides a 20 V output profile. Without a 20 V PD source the built-in conversion chip cannot produce the required 12 V. Verify that your PD adapter or power bank lists 20 V support before purchasing.

Questions about this item

Does the PD chip or the DC connector wear out first?

The aluminium-alloy shell and 4.5 mm cable with reinforced tail protection are built for repeated bending, while the internal PD chip is a solid-state component with no moving parts.

What limits continuous output when powering a router or monitor all day?

The cable’s smart PD chip negotiates 20 V from the source and converts it to a fixed 12 V 3 A maximum, so the 3 A ceiling is the hard limit regardless of charger capacity.

How warm does the aluminium shell get during extended use?

The alloy housing acts as a heatsink for the PD conversion chip, and the 4.5 mm conductors keep resistive loss low, so the shell stays only slightly warm even at full 12 V 3 A load.
