The 12V to 5V USB Power Converter works well

Overall, the install was simple. I traced the old control panel cables back to the panel and wired in the 12v system in. The converter installed easily and works just fine with my TabA 9.7.

Great Power Supply

This works great. I mounted it to the stud with 2 screws and then connected it to the wires coming from the main board. My Fire Tablet has continuous power now. I highly recommend this for your display and power

Superb system

The two Konnected Pro devices plus the accessories to power a few fireOS devices are amazing. Many possibilities using SharpTools through numerous platforms to choose from to fully customize a home automation system.

Worked like a charm!

Easy install, good instructions, very compact. I would suggest offering a lightning cable option, but was not a show stopper! I replaced my old ADT panel with an iPad Mini
