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

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.

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.

Would barely run a USB LED light bar. They were significantly dimmer on this USB step down than on a 2.4A USB hub, so I assume its 1.5A per port, not 3A each.

Works as advertised

What is these to say? Does exactly what it says. Took one minute to hook up to my cars fuse panel and now I have two USB ports behind my dash for powering my Bluetooth receiver and GPS without cables running to my cigarette lighter.

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.

Works as expected!

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

Excelente producto, mejor funcionamiento de lo que esperaba, carga bastante rapida

Works well. Should include t-tap for this price
