Review on 🚗 High-Speed Car Charger with Volt Meter & LED Display for Phone X/Xs/XR/Xs Max and More by Terrance Fisher

This is MUCH better than I expected! It will show you the voltage of your vehicle as you can see in the picture, but when you connect it to the lower 3 amp circuit at the bottom of the plug it will show you the output current and voltage of the device you are charging. , which is great for charging drones and batteries that don't read. You know how far in charge you are by using this plug. Really sweet!
