Gen 3 12V Power Supply for Starlink Standard Gen 3

Gen 3 12V Power Supply for Starlink Standard Gen 3

Our Gen 3 12V Power Supply plugs directly into the Gen 3 Starlink router and runs your dish straight off a 12V or 24V battery. No inverter needed. Powering Starlink through a large inverter wastes idle draw (30 to 50 watts on a 3000W inverter), which adds up to hours of lost battery life when you are off-grid. This power supply cuts that loss by converting your battery power directly to the voltage Starlink needs.

Simply unplug the 110V Starlink power supply, plug in our 336W power supply, and connect it to a 12V or 24V power source (input voltage range: 10 to 30V). Our converter boosts this to the 56V required by the Gen 3 router and dish. It also continuously regulates voltage, so the dish gets stable power even as battery voltage shifts. A small indicator light is built into the converter, making setup and installation much easier by confirming the unit is powered and running.

After testing numerous power supplies, we finally had one manufactured overseas. To eliminate any concern about ripple voltage (and subsequent dropouts and/or reduced speeds), we install a capacitor as well as the appropriate barrel connector that works seamlessly with the Starlink Gen 3 router. Off-the-shelf converters did not hold up, so we built our own with the correct output, filtering, and connector for reliable Gen 3 operation.

Power consumption tested over 1 hour with constant upload/download internet: 63 Wh (4.5A at 13.8V). Actual draw varies with usage and environment.

** NOTE: Using the snow melt function draws an additional 120W and cannot be used with a cigarette lighter plug, as most vehicles have a 10A limit.

** If wanting to extend the barrel connector length, we recommend adding a barrel connector extension. For input power wiring, size the wire properly based on the added length and current.

Please select the appropriate connector for your application from the drop-down: bare wire leads, ring terminals, or cigarette lighter plug (must be a 15A or greater cig plug). Bare wire is ideal for custom installs. Ring terminals are ideal for direct battery connections. A cigarette plug is the easiest option with a properly rated outlet.

Important Information

Compatible with Starlink Gen 3, 4, and 4X Standard that use the Gen 3 router. Not compatible with the Starlink Mini, which already accepts 12-48V DC directly. For the Mini, use the Mini 12V DC Power Cable instead. Standard 4 uses the Mini Router, while Standard 4X uses a different router and connector configuration that is incompatible. If you are unsure which router you have, compare it against the photos at starlink.com/specifications, or send us pictures of your dish and router, and we will verify before you order.

The unit ships pre-assembled and ready to install with your selected connection type. It is sold as a complete unit, so individual internal components and connectors are not available separately.

Troubleshooting. If your battery reads 12V but Starlink won't power on, the issue is almost always a voltage drop under load, not the power supply itself. A battery can show full voltage at rest and still sag once the dish starts drawing power. Check wiring size (the most common cause), state of charge, fuse condition, ground connections, connection quality, and any corrosion in the circuit. Testing directly with a known-good battery helps isolate wiring problems.

12V Connection Type

Choose how the power supply connects to your 12V or 24V power source. All three options ship pre-assembled with your selected connector already attached. The unit is sold complete, so connectors aren't available separately after purchase.

• Bare Wire Leads: Unterminated wire ends, best for custom installs where you're wiring directly into a fuse block or panel
• Ring Terminals:5 ft cable with ring terminals attached, best for a direct, permanent connection to battery terminals
• Cigarette Lighter Plug: 5 ft cable with a plug end, the simplest option if you have a properly rated 12V outlet available (outlet/plug must be rated 15A or greater)

Note: The cigarette lighter plug option cannot be used with the snow melt function active, since snow melt draws an additional 120W and most vehicle cigarette outlets are limited to 10A. If you plan to use snow melt, choose bare wire or ring terminals wired to a fused circuit instead.
