The AIR GEAR MiniLink requires 12 volt power from the 7-way trailer plug. Nearly all travel trailers provide this, since the 7 way trailer plug is connected to the trailer&apos;s onboard batteries.In some trailers, a device may be installed that prevents power from the trailer batteries from reaching the 7-way plug. This device may be called:<ul style=" text-decoration: none;"><li>DC-DC converter</li><li>DC-DC charger</li><li>battery isolator</li><li>Redarc charger</li></ul>If you suspect your trailer may have one of these devices, you can check the 7-way trailer plug before purchasing a MiniLink.<h2 id="how-to-test-your-7-way-plug-for-compatibility">How to test your 7 way plug for compatibility</h2>To conduct this test, you&apos;ll need either:<ul><li>a voltmeter (option 1)</li><li>a common automotive blade fuse (option 2)&#xA0;</li></ul><h3 id="option-1-test-with-a-voltmeter">Option 1: Test with a voltmeter</h3>Put the red lead of a voltmeter in the &quot;Aux 12 Volt + (Black)&quot; terminal of the 7-way cable, and the black lead in the &quot;Ground (White)&quot; terminal, &#xA0;as shown in the diagram below.<img src="https://attachments.gorgias.help/kREQL2bpB5xMl8n3/hc/bVpA37lvzv6J5oEd/2024091217-cacb9c2f-dd54-4954-9617-aaf1946fc264-7-way-wire-diagram%20trailer%20end.jpeg" style="width: 445px;" class="fr-fic fr-dii">IF the voltmeter indicates more than +9.0 volts, THEN you can use MiniLink.<h4 id="if-the-voltmeter-indicates-less-than-90-volts">IF the voltmeter indicates less than 9.0 volts:</h4><ul><li>Make sure you are making good contact with the metal tabs inside the plug, with both leads of the voltmeter, at the same time.</li><li>The connectors on the 7-way plug may be corroded or dirty, and unable to transfer electricity as they should.

It needs to be rated for 10 amps or higher.If you don&apos;t have such a fuse available, you can pull one from the trailer&apos;s fuse panel temporarily, or buy one at any auto parts store. There&apos;s also a spare mini fuse in the AIR GEAR Portable Solar Kit (if you purchased it after May 1, 2025).<img src="https://attachments.gorgias.help/kREQL2bpB5xMl8n3/hc/bVpA37lvzv6J5oEd/2026051422-48b9f345-5d14-45f3-948b-4905681e9c37-testing%2012v%20power%20with%20fuse%20at%207-way%20plug.jpg" style="width: 273px;" class="fr-fic fr-dii fr-fir">Orient your 7-way trailer plug with as shown, with the flat ridge at the top. Insert the fuse in the top two slots. This will connect the 12V+ pin from the trailer&apos;s battery, to the pin for the trailer&apos;s clearance and tail lights.The clearance and tail lights should go on.&#xA0;This shows that you have 12V power at the 7-way connector, which is good.If you cannot get the clearance lights to illuminate, there is probably no 12V power at the 7-way plug. This is the reason your MiniLink isn&apos;t able to work.<a href="https://air-gear-help-center.gorgias.help/en-US/no-power-at-7-way-plug-6223055" id="isPasted">Click here to explore further.</a> <h2 id="minilink-compatibility-with-starlink-models-and-generations">MiniLink Compatibility with Starlink models and generations</h2>The AIR GEAR MiniLink is compatible only with Starlink Mini and Mini X.

No power at 7-way plug

A Starlink Mini consumes an average of 18-20 watts when in use, and 15 watts when idle. (More power is required when starting up, and when the "snow melt" mode is on.). You can roughly estimate the amount of time you'll be able to power your Starlink

A Starlink Mini consumes an average of 18-20 watts when in use, and 15 watts when idle. (More power is required when starting up, and when the &quot;snow melt&quot; mode is on.)You can roughly estimate the amount of time you&apos;ll be able to power your Starlink Mini, from any battery bank.First, start with an estimate of the capacity of your trailer&apos;s batteries, using the chart below.<h3 id="capacity-of-battery-banks-in-most-travel-trailers-assuming-typical-battery-size-and-capacity">Capacity of battery banks in most travel trailers (assuming typical battery size and capacity)</h3><table style="width: 100%;"><thead><tr><th style="width: 33.3333%;">Battery type</th><th style="width: 33.3333%;">Number of batteries</th><th style="width: 33.3333%;">Watt-hours of usable capacity</th></tr></thead><tbody><tr><td style="width: 33.3333%;">Lead-acid (including AGM)</td><td style="width: 50.0000%;; width: 33.3333%;">1</td><td style="width: 33.3333%;">500 Wh</td></tr><tr><td style="width: 33.3333%;">Lead-acid (including AGM)</td><td style="width: 50.0000%;; width: 33.3333%;">2</td><td style="width: 33.3333%;">1,000 Wh</td></tr><tr><td style="width: 33.3333%;">Lithium Iron Phosphate (LFP)</td><td style="width: 50.0000%;; width: 33.3333%;">2</td><td style="width: 33.3333%;">2,500 Wh</td></tr></tbody></table> Second, estimate how many hours per day your Starlink Mini will be connected to power via the AIR GEAR MiniLink. Don&apos;t include time when the Starlink Mini is expected to be in &quot;Sleep Mode&quot;. (Sleep Mode is an optional setting in the Starlink app that powers down the unit during the night.)Third, multiply the estimate of hours per day of usage by 20 (Watts). This gives you your total Watt-hour consumption per day. For example, 4 hours usage per day X 20W average = 80Wh per day.Fourth, divide the battery capacity (in Wh, from the chart) by the estimated consumption per day. For example, 1000 Wh / 80Wh = 31.25 hours.Divide hours by 24 to get days of runtime. For example, 31.25 hours / 24 = 1.3 days.<h3 id="important-note">Important note</h3>Actual runtime will probably be less than this calculation implies. That&apos;s because this calculation doesn&apos;t take into account the consumption of other appliances in your RV that will also be using the batteries. Usage of items like the furnace, electric refrigerator, on-board inverter, etc., will greatly reduce the length of time your trailer batteries will last.
