### ⭐⭐⭐⭐⭐ Save money
*by C***R on March 25, 2025*

Works great saved me from buying a new one

### ⭐⭐⭐⭐⭐ Starlink Mini boost
*by P***R on November 23, 2024*

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.

### ⭐⭐⭐⭐⭐ Did well as described.
*by A***N on September 16, 2023*

Made 24.3 Vdc at various current levels. Did not get very warm at all. Ran 142 watts thru it for my loads for half an hour, feeding a charge control system for testing, worked just fine for need. Fuse was there.
