Review: Starlink Mini boost - I installed an exterior plug on our camper for our Starlink Mini, runs off the camper's 12V batteries. Thankfully saw a YouTube video that noted straight from 12V will not power the Starlink Mini through the provided 50 foot cable. Installed this between batteries and exterior jack and works flawlessly.
Review: Defective - I applied 12v dc to the positive and negative input wired, instantly wires got hot, unit did not work.
