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 Hall

I used this on the cigarette lighter port on my 06 STI. I had to carve the port a bit as it's a bit larger than a regular cigarette lighter but I was able to make it fit just as well 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, typically around 12.5 when the car is in accessory mode, which drops off when I turn on the fan or other accessory, and typically stays around 14.4 when the engine is on is. I have a moto z and my wife has a samsung and they both see it as a turbo/fast charger.
