Starlink Mini

DC-TYC Mini Starlink cable is a DC-to-Type-C power supply cable specially designed for Starlink Mini (Starlink Mini version satellite terminal). Its core function is to provide stable 20V PD protocol power transmission for the mini Starlink antenna without transmitting data (data is transmitted through an independent Wi-Fi link). It is suitable for scenarios such as vehicle-mounted, outdoor, and portable use. The following are the detailed specifications and application guidelines
I. Core Positioning and Basic Definition
The DC-TYC Mini Starlink cable = DC interface + Type-C interface + dedicated power transmission cable. It is a key accessory of Starlink Mini, used to replace the official standard 15m long power cord and achieve flexible power supply for Starlink.
Core parameter specification description
One end of the interface Type is DC (compatible with the Starlink mini antenna DC5521 interface), and the other end is Type-C (supporting PD fast charging protocol).

Power supply standard: 20V/5A, 100W PD protocol (official minimum requirement), some products support 140W (20V/7A)
18AWG pure copper core wire gauge (low resistance, reduced power loss)
The common lengths of the mini versions are 0.2m/20cm, 1m, and 1.8m. The standard version is 3m/5m, and the extra-long version can reach up to 10m
Some products have a waterproof rating of IP67/IP68, making them suitable for outdoor use
Functional positioning: Only power supply, no data transmission (data is transmitted from the antenna to the router via Wi-Fi)
Ii. Working Principle and Power Supply Mechanism
The core of the DC-TYC mini Starlink cable is the PD (Power Delivery) fast charging protocol, and its workflow is as follows:
plaintext
Power supply (PD charger/power bank/car power supply) → Type-C terminal → 18AWG copper core wire → DC terminal → Starlink mini antenna

20V DC transmission (PD protocol negotiation)

Antenna built-in power management module → Voltage reduction to supply power to each component of the antenna (phased array radar, processor, RF module)
Key technical points
PD protocol handshake: The voltage/current at both ends of the cable is automatically negotiated to ensure a stable output of 20V, matching the requirements of the Starlink mini antenna
Power dedicated line design: No data transmission line pairs, focusing on power transmission, reducing resistance, and enhancing efficiency
Safety protection: Built-in overcurrent, overvoltage and short-circuit protection to prevent equipment damage
Low-loss design: 18AWG thickened copper core (thicker than ordinary USB cables), reducing power loss during long-distance transmission
