SMUGDESK USB-C Female to DC Power Adapter 100W 20V 5A 4.72in IPX4 18AWG

SKU CH-PGMM-G81PV

Waterproof 4.72-inch USB-C female to DC adapter delivers 100W at 20V/5A via 18AWG copper for stable outdoor power

  • Delivers stable 20V output via smart PD trigger chip
  • 18AWG pure copper wiring minimises resistance and power loss
  • IPX4-rated sheath resists splashes, dust and moisture outdoors
  • Compact 4.72-inch design suits RV, camping and rooftop installs
  • Reuses existing PD USB-C supplies instead of bulky original adapters

Purpose and Users

This adapter converts a USB-C Power Delivery source into a stable 20 V DC output for devices such as the Starlink Mini and compatible outdoor routers. It suits anyone who wants to power that equipment from a portable PD power bank or charger instead of the original bulky supply. Buyers needing a different output voltage or a higher wattage than 100 W cannot use this cable.

Decisive Specification

The built-in smart PD trigger chip negotiates and locks a steady 20 V at up to 5 A, delivering a maximum of 100 W to the DC terminal. Without a PD source that can provide exactly 20 V the adapter will not function, so the power bank or charger must support that fixed voltage profile.

Thermals, Noise and Power Draw

Thick 18 AWG pure copper conductors keep resistance low and prevent overheating during continuous high-current operation. The short 4.72 inch length and waterproof outer sheath protect the connection from splashing water and dust in RV, camping or rooftop installations. The passive design adds no fan noise and draws only the power required by the connected device.

Questions about this item

What does the 100W 20V 5A rating mean when I plug this into my Starlink Mini?

The built-in PD trigger chip negotiates a steady 20V from your USB-C power bank or charger, delivering up to 100W so the Starlink Mini receives stable power without voltage drops during continuous outdoor use.

How does the USB-C female input limit what power sources I can use?

The USB-C female port only works with PD-capable chargers or power banks that can supply 20V at 5A; standard 5V or 9V outputs will not trigger the required voltage, so the adapter will not power your device.

What do I need to check so the 4.72in cable and DC terminal actually fit my outdoor router?

Measure the DC jack on your router — the adapter's custom terminal must match its inner and outer diameter and polarity; the short 4.72in 18AWG cable is designed for tight mounting on Starlink Mini or similar gear.
