Screen/display is small but it actually does show the voltage that the car is at. The volt reader is great! The second picture is once the vehicle is started. Helps to keep track of my battery. As well as a volt meter.

Pd quick charging my pixel phone at the same speed as my home charger. Initially it starts off as a super fast charger but then shortly changes to fast charge.

Worst thing of this product is it’s very loose where it plugs into the car cigarette lighter socket. Two months in a small cloud of white smoke comes out from behind the charger in the socket and after that the product is completely dead.

It just keeps saying it's connected and super fast charging, but there is zero power gain on my phone, just power loss. The charging display (for android) is below the cord connection. The font display is to small for my vision strength.
