Review on 🔌 YONHAN Quick Charge 3.0 Dual USB Charger Socket with Waterproof Power Outlet, Fast Charge, LED Voltmeter, Wire Fuse DIY Kit for 12V/24V Car Boat Marine ATV Bus Truck and more - Red by John Langdon

I used this on the cigarette lighter port on my 06 STI. I had to chisel the port a bit as it's slightly larger than a regular lighter, but I was able to get it to fit in the same place and the door still closes over it. Installation was easy as I was able to take the pins out of the factory seat belt and slide them straight onto the pins on that belt (even as latches). I'm surprised at how accurate the voltmeter seems to be, it's usually around 12.5 when the car is in accessory mode, which drops when I turn on the fan or other accessory and usually stays at around 14.4, when the engine is on. I have a Moto Z and my wife has a Samsung and they both see it as a turbo/fast charger.
