Car Hard Wire Charger, 12V to 5V Dual USB Female Port Charging Cable Direct Link Hard Wired Step Down Converter Power Supply for Dash Camera Car DVR GPS

Disappointed- one side quit working on the second day of use

I wanted to hard wire a cable for my GoPro camera and my tablet that I use for GPS in my Polaris RZR. I connected this up to the 12v bus bar under the hood and put the unit under the dash and then ran TOPK magnetic usb power cables under the dash directly to my devices. Now my dash is clean and my devices can be popped out and disconnected super easy.

Work well in my Side by side

Worked perfect to replace my existing one in camper to power wifi router. It was identical and had usb but I bought a usb plug with correct power adapter at end to plug in to the usb and to my router. Total install time took 3 minutes.

Needed a way to connect 5V light strings to a 12V AGM battery for camping and this is an inexpensive and easy way to accomplish the task without having to build your own converter.

The usb output of this isnt 5V but 8.35 anything that is sensitive like an esp get fried by this, even a pi that has its own overvoltage protection wont stay on for more than a few seconds when being powered from this regulator.

Everything as advertised. I simply tapped the hot (and ground) on the map light in my car to add a USB for dash cam power in the headliner. Less than 15 minutes to get everything done. Very happy.

Performed various trouble shooting and confirmed the charger itself has failed.

Wired to automatic rear view mirror wiring. I have a GoPro mounted to the front side of the mirror and I use my iPhone in a RAM Mount on the front windshield while racing. Now I don’t have to change batteries during a race weekend. Works awesome.

Perfect for anyone who has a basic idea on how to hardwire. I wired mine to a fuse tap, both Usbs work as they should.
