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

This unit is small enough to conceal easily and the USB ports are sturdy and the cords are about 6 inches long to place where needed.

I bought this as part of my Acuras entertainment system upgrade to add a second USB port. The primary port is from the updated carplay stereo. I ended up mounting the USB in the dash panel under the stereo using two square USB connectors and attached this to one of them. NOTE: I am only using ONE of the USB ports from this device. For my use case, this unit works great.

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

No instructions shown which wire is Positive! Shorted out my IPOD.

I used these to install dash cameras and the last batch has had three fail out of four. It appears that they are overheating when installed between the headliner and roof of the car, causing the power to cycle on and off (or just stay off) going to the USB port. This might be good for a home project, but I strongly recommend going a different route if you are going to use these in a car.

Just what I needed

This gadget is a great way to hard-wire USB powered devices in your car. Whether thats a dash cam, Alexa, radio detector, or whatever. This makes it a snap. All you basically need to do is wire this to the hot side of your fuse block and forget it.

Easy to install a very nice product

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.

Works as advertised. Worth adding to our vanagon
