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 Deon Sweeney

I had to lift the hood and check the battery with a volt meter 2 or 3 times a day because the battery was dead. This gadget has made battery monitoring easy. I just look out the window and make sure my battery is at 12.0 or higher. If not, I crank it to avoid a low battery that won't start the car. It is so well made, easy to read, easy to use etc. I bought one for my wife and one for my daughter. So I've bought this item three times already. If you need to know how charged your battery is, this is the best device in town.
