Review on 🔌 Black QC3.0 Car Charger Extension Cigarette Lighter Adapter and Socket Splitter with Voltage Meter, 3 USB Ports - Compatible with iPhone 8/7/X/6S/XR, iPad, Samsung Galaxy S9/S8, GPS, Android Phone by Alexander Scharon

This gives an accurate reading of my car battery. Now I don't have to worry about my car accidentally dying. The built in 12V plug seems *a bit* big, but even for this miniature car charger I have it. it still fits and works perfectly. UPDATE: 5-6 months later and it's still working. Some car chargers still fail from time to time. UPDATE: It's been 11-12 months and it's still working. This tells me that my car battery needs to be replaced before winter. I also decided to hook up various car voltage readers I have, 3 others I bought can't remember where. They all started around the same time. But all the non-revains were slower, couldn't show me the voltage change very quickly after starting the car or turning on the AC etc, or they show at a lower voltage than here, and then maybe catch up randomly in the same way as it falls again, mixed results. But I'm glad I have this one, no mixed results, all is well and I'm glad to know it's probably one of the best working ones you can get! It was very reliable. Over time I realized that a slightly larger plug is actually a lot more convenient for plugging and unplugging things without turning off the voltage reader. The thing never moved, didn't even turn a bit, it's stuck in the car. I checked Whether the inside of the carport is scratched or deformed by the voltage reader, it looks the same as before, it will not damage my car. I really love this shop. I would take a picture
