Review on 🚗 USMEI Car Charger with Quick Charge 3.0, Dual USB Adapter, Voltmeter Display - 36W Fast Metal Charger for iPhone Galaxy S10 S9 S8 S7 S6 Note LG Nexus Pixel and More by Matt Eason

Just enough to walk by when I'm in my car with the radio on, I can see with a quick glance if my battery is getting low and charge it up. If you need an ultra-accurate battery tester, however, this will suffice if you need to watch for significant voltage drops. It has been used on two different cars since 2019 without any problems, the screen is nice and clear, the finish is nice and solid. with some weight. Obviously a fast charger works well with a good charger, I've had issues with some cables but obviously with good quality cables you won't have a problem.
