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

Works as intended no problems.

This is a great usb charger

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.

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

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 well. Should include t-tap for this price

No instructions but very easy to install with 2 wires, Red (+) and Black (-), decent quality product for the price. USB charges devises fast.

I wanted a switched 12 volt source for my wireless phone charger and my flashlight charger. This got the job done. Neatly tucked away out of sight.

Easy to install a very nice product

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