30 meters Starlink Mini DC Ethernet Cable 2 in 1 Waterproof DC USB-C Charging to RJ45 Ethernet Cable Power Supply Cord

The product you’re describing—a 30-meter, 2-in-1 DC power and Ethernet cable for Starlink Mini—is a real, third-party accessory available from various manufacturers. It combines a DC power line and an RJ45 Ethernet line into a single cable assembly, often with a USB-C adapter included for flexible power input .

📊 Key Specifications to Expect

Based on listings from brands like FLEK and HanCenDa, here are the typical specs for this type of product:

• Cable Length: 30 meters (98 feet) is a standard length offered for this cable type .

• Wire Gauge: Look for 20 AWG or thicker (lower numbers are thicker). FLEK’s 30m version uses 26 AWG for the data pairs, but power delivery over 30m requires careful attention to the power conductor’s gauge .

• Data Speed: Most listings advertise 1000Mbps (Gigabit) data transmission .

• Power Handling: Some cables claim support for up to 10A and 100W, which is necessary for the Mini’s startup surge .

• Weatherproofing: Advertised as waterproof or weather-resistant for outdoor/RV use .

• Compatibility: Designed specifically for Starlink Mini (not Gen 2 or Gen 3) .

⚡ Critical Performance Warning for 30m Runs

The main challenge with a 30-meter cable is voltage drop. The Starlink Mini requires a stable 30V DC input for long cable runs; using lower voltages like 12V or 20V USB-C will cause the dish to restart or fail at this distance .

• You must use a 30V Power Source: To power a Starlink Mini reliably over 30 meters, your power supply (or a step-up converter) must output 30V DC . A standard 12V car socket or a 20V USB-C power bank will not work over this distance without a converter.

• The “USB-C Charging” Label is Misleading for Long Runs: While the cable might include a USB-C adapter, using USB-C PD for power is only compliant for cable runs up to 5 meters . For 30 meters, the DC input must be 30V.

💡 Recommendation

If you buy this 30m cable, ensure you have a 30V DC power supply (or a 12V-to-30V step-up converter) to feed into the cable’s DC input. Without this, the cable will not deliver sufficient voltage to the Starlink Mini at that length.
