I had a battery in my 2011 fiesta that was acting up. It was not really holding a charge anymore. I let my husband know that I thought my battery was having an issue. He bought me this wonderful car charger. I have a Samsung s25ultra. It shows me the voltage of the battery before I turn on my car. After starting my car it shows the voltage again. After using this tap for 3 days I came to the concussion that my battery needed to be replaced. I know i could have gone to oreily and it checked but I wanted a new tap to charge my phone. This served both perfectly.

My Ford F150 came from the factory without a volt gauge. My main concerns is it accurate, will last, numbers easy to read they are! This manufacture was one of the few that listed actual size of the read out, how it's made, etc.

I like it and will be getting another one soon to go into the other car in my stable that also doesn't have a voltmeter in the dash. It is important to me to know what the electrical system is doing on my automobiles, and if the dashboard doesn't indicate voltage, this is an ideal solution. That it is also two kinds of USB charger is icing on the cake.Good stuff.

Quality accessory which provides both charging ports and a volt meter. Only complaint is blue numbers on volt meter seems to be the standard and are unreadable in bright daylight sun they should be white.

works as it says....my display is accurate as measured w/ dvm...my truck has a smart alternator which probably why some people are saying their readings are off...mine does not get warm or hot to the touch...overall this is a quality unit with a clear display and easy to read

My Samsung phone shows superfast charging when into the 3.o USb C port ! AWESOME !!

Super low profile installation.The battery voltage feature is awesome, helpful especially in older cars.Works great if all you need is a USB and USB-C; but if you need more may want to opt for their other designs.

Display is sharp and legible. I use this in my airplane to convert to USB as well as keep an eye on the system voltage (identify an alternator failure).
