Starlink On the Go: 12–56V DC Power Supplies for Portable and RV Use

Powering Starlink while travelling in a caravan, RV, or boat can drain your batteries quickly if youre relying on an AC inverter. A dedicated Starlink DC power supply delivers the voltage your terminal needs directly from your 12V56V system, avoiding the waste and heat of double conversion.

Up to 31% power savings compared to using AC inverters
Direct 12V-56V DC input for RVs, boats, and off-grid setups
Elimination of double power conversion (DC to AC to DC)
Extended battery life in mobile applications
Greater reliability than inverter-based systems

Running Starlink off-grid presents a challenge. Traditional setups force you to convert your 12V battery power to 240V AC through an inverter, then back to DC for your Starlink. This double conversion wastes precious energy, with research showing inverters can increase Starlink's power consumption by up to 31%.

A dedicated Starlink DC Power Supply connects directly to your 12V system, delivering clean, efficient power without these conversion losses.

SpaceTek Australia has spent over 25 years solving remote connectivity challenges. Our StarPower range of reliable Starlink DC power solutions is designed for real-world Australian conditions to help you stay connected efficiently on the move.

Is an RV Setup Right for You?

Taking Starlink on the road opens up incredible possibilities for Australian travellers. But before you head out, it's crucial to understand the requirements for a successful mobile setup.

Power Consumption: The Reality Check

Starlink is power-hungry. The dish typically consumes 75-100 watts during active use, dropping to around 20 watts when idle. In colder regions, the snow melt function can spike this to over 200 watts. At 12 volts, a 100-watt draw pulls about 8.3 amps per hour, which adds up quickly.

This is where a dedicated Starlink DC Power Supply is essential. Traditional AC inverters waste up to 31% of your power through double conversion—energy that disappears as heat instead of keeping you connected.

Your Battery Bank: The Foundation of Freedom

To run Starlink comfortably, you need an adequate battery bank. For example, 10 hours of use at 100 watts consumes 1000 watt-hours. A standard 100Ah lithium battery provides about 1200 watt-hours, meaning Starlink alone could use most of its capacity. By using an efficient Starlink DC Power Supply, you reclaim that 31% of lost power, potentially saving you from needing an extra battery.

Mounting and Networking

Your dish needs a clear view of the sky, so a secure mount is vital. At SpaceTek Australia, our Starlink RV and portability mounts, adapters, and accessories are engineered for tough Australian conditions.

For the best performance, many travellers bypass the standard Starlink router for their own networking equipment, which offers better range and reliability. A quality Starlink DC Power Supply like our StarPower range simplifies this integration, giving you the flexibility to build a network that suits your travel style.

Featured Product: StarPower V2 12V / 24V DC Power Supply

The StarPower V2 is your gateway to efficient Starlink power for mobile adventures. This robust Starlink DC Power Supply powers your Gen 1, 2, or 3 Standard terminal directly from your 12V or 24V system, eliminating the energy waste of inverters. With a wide input voltage range of 11-36V DC, it adapts to any caravan, boat, or remote work setup.

A key feature is its direct router bypass capability, allowing you to connect your own router for complete network control. The unit includes multiple connector options (Anderson, DC jack), a PoE LED indicator, and an unregulated DC pass-through to power your router. For Gen 2 users, a simple cable modification is required—cut your Starlink cable and terminate it with a Cat6 plug using the T-568B standard. This compact powerhouse (160 x 100 x 60mm) fits into tight spaces while delivering up to 31% power savings.

Avoid attempting DIY methods, as these can trip the internal fuse or potentially damage your cable and terminal.

Featured Product: StarPower V4 – Ultimate Power Solution

For maximum versatility, the StarPower V4 is our flagship Starlink DC Power Supply. This powerhouse is engineered to work seamlessly with Gen 1, Gen 2, Gen 3, and the Starlink Mini, making it a future-proof solution for any setup. It can be powered by standard 110-240V AC or an external DC source.

The StarPower V4's standout feature is its ability to bypass the default Starlink router, putting you in control. This is invaluable for Gen 2 users with failed routers or anyone wanting to integrate a robust third-party router, like our Grandstream business-grade options. Its modular bundle system lets you build the exact setup you need, from a simple PoE injector to a comprehensive kit with a power supply, adapter, and router. This ensures you only pay for what you need, with room to expand later.

IMPORTANT: Always connect the power source before turning the unit on to prevent damage.

Installation Steps for a Starlink DC Power Supply

Installing a Starlink DC Power Supply is straightforward but requires care to ensure a safe, efficient system. Here are the key steps for a successful installation.

1. Preparation and Materials Before you start, gather your Starlink DC Power Supply, appropriately sized wiring (10AWG or 12AWG), and a correctly rated fuse with a holder. For marine or harsh environments, use marine-grade components.

2. Power Source and Fusing This step is critical. Disconnect your battery completely before working. The golden rule is to install your fuse as close as possible to the battery's positive terminal. A 30A fuse is common, but always check your unit's specifications.

3. Wiring and Connection Use correctly sized wire to minimise voltage drop, especially over longer runs. Double-check your polarity (positive to positive, negative to negative) to avoid damage. While our StarPower units have reverse polarity protection, it's best to get it right the first time.

4. Connecting to the Starlink Dish For Gen 2 terminals, this often involves modifying the Starlink cable by cutting it and terminating it with a Cat6 plug using the T-568B standard. If you prefer not to cut cables, our Starlink SPX to RJ45 adapter offers a simple, no-cut solution.

5. Positioning and Power-Up Position your dish with a clear, unobstructed view of the sky. Once everything is connected, switch on your DC power source. The dish should begin its boot-up sequence and find satellites within minutes.

Troubleshooting Common Issues

No Power: Check all connections are secure, especially XT60 connectors. Verify input voltage with a multimeter and check for a blown fuse.
Slow Speeds: This often points to a cable modification issue. Re-check your T-568B wiring. Poor quality power supplies can also interfere with the connection.
Snow Melt Problems: This can occur if your input voltage drops below 20V. Ensure your battery bank can maintain adequate voltage under load.
