Tablet power

Making the usb c thinner and on a 90 angle would be better

Powered dash cam

The USB plug was wrong for my Nextbase dashcam, but I cut and soldered the proper plug onto the adapter with no problem. Works as intended for my 2021 Toyota Highlander Hybrid. The adapter unit and wiring all fit under the rear view mirror housing where I tapped into 12 volts using my voltmeter. I now have a clean installation with no dangling wires running to the lighter socket. My only complaint would be there should be clear pictures of the available power plugs on the adapter description to avoid confusion when ordering .

Works As Advertised

Four. Stars because the finish could be a little better.. with that said, it does what it should do and holds the tablet in place perfectly. Pictures attached..

This 12V to 5V USB Power Converter worked perfect!

I used this Konnected 12V to 5V USB power converter to power an iPort Surface Mount iPad station, as iPort no longer makes their converter. With an existing 12V transformer (located remotely) powering a 2-wire connection at the iPad station I added this converter, along with a standard USB to lightning iPad charging cable (using the female USB connection on the Konnected converter kit) and viola! My iPad stays charged. Its about as compact as the old iPort converter and fit inside the single gang electrical workbox. Does what I need and at 1/4 the price of the now disco'd iPort converter. Thanks Konnected!

Great Converter

Great converter. I was able to replace my alarm control panel with an Amazon Fire tablet and power it with this converter. Quick and easy installation.

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

Awesome products!

This guy is simple to wire in, I just used my old leads from my old panned Connected them to Konnected aux and I have power to my tablet. Now we just have to get something to work more efficiently on the tablet for the system.

12V to 5V USB Power Converter

The photo I ordered from clearly showed a straight through USB-C connector, but I received a right-angle USB-C connector. I already have a right-angle connector from a previous order, so these two parts are of no use to me because I need a straight through connector.

USB-C power converter

Konnected is awesome for alarm automation and self monitoring. The power converter is necessary to charge my new Amazon Fire Tablet that replaced the old alarm panel. Looking forward to working The Tiles features with my Konnected devices. Great support from the Konnected staff.
