Review on 🚗 High-Speed 3-Port USB Car Charger, 12V/24V Input, QC3.0 Output 4.8V, Cigarette Lighter Voltage Meter, Compatible with iPhone, iPad, Samsung Galaxy, and USB Charging Devices - Silver by Eric Krull

I am very happy with it. I had it for several months and it was very accurate. I have two other digital readouts and a digital multimeter and they are all within a tenth of a point of each other. It also reads the correct voltage from your phone. The blue light isn't distracting at all, which is nice. The fit is almost perfect for me to close the cigarette lighter door while still plugged into my Lexus, but not quite. I like that it's fairly secure and takes a bit of effort to figure out. The USB ports are still tight even after three months of almost daily use. That is very gratifying.
