Starlink Mini USB-C to DC 20 V cable

This 6.6 ft weatherproof cable converts a USB-C Power Delivery source into a 20 V DC barrel output for the Starlink Mini. A built-in PD smart chip negotiates the required voltage so the terminal can run from a compatible power bank or wall adapter. The copper conductors and male-to-male terminals are rated for 20 V at up to 5 A.

Suits portable Starlink Mini setups.

Travellers and field workers who want to replace a bulky 110 V UPS with a pocket-sized PD power bank will find the cable convenient. It also powers Asus laptops, LED strips, amplifiers and robotics boards that accept a 5.5 × 2.1 mm 20 V jack. Buyers who need a permanent indoor installation fed from mains voltage should look at a dedicated AC power supply instead.

Requires a PD source that delivers 20 V at 100 W

The cable only functions when the attached USB-C charger or power bank explicitly supports 20 V output and can supply at least 100 W. Lower-voltage PD profiles such as 5 V or 9 V will not activate the conversion, and undersized sources will current-limit or shut down. Verify the 20 V capability of your PD device before purchase.

Questions about this item

What USB-C Power Delivery standard does this cable use to deliver 20V output?

It uses a built-in PD smart chip to negotiate 20V at up to 5A from a 100W or higher PD charger or power bank.

What is the barrel connector size and polarity for the DC end?

The DC plug measures 5.5mm outer diameter by 2.1mm inner diameter, wired for 20V centre-positive.

How do you connect it, and what is the common mistake?

Plug the USB-C end into a PD source that confirms 20V output, then attach the DC plug; the mistake is using a charger that only supplies 5V or 9V.
