Review on 🔌 DROK Dual Power Adapter 3A/15W: 8-22V to 5V Double USB Cable Connector for iPhone, iPad, Nokia, HTC by Eric Jefferson

I bought them to install in my car to power the Bluetooth adapter to turn on with the car and turn off when the car stops. I installed one of these and sometimes it didn't work when turned on. I tried the second one and it was worse. I requested the return but I didn't receive it in time, my loss. I don't know what the problem is, but I've bought several different ones that worked as expected and hooked up exactly the same.
