[Pure Copper] USB C Car Charger, SUPERONE 45W Dual USB Car Charger Adapter with 27W/20W PD Port, Fast QC3.0 LED Voltmeter for iPhone 15 14 13 Max/Pro/Plus/Mini, Pixel 7/6/5, Samsung S22/21 More

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.

Works great. Verified voltage with a voltmeter and it reads exactly the same. I use it to monitor my voltage for my loud stereo and it does a great job, while adding the benefit of charging your phone if needed. Digital screen is bright without being distracting.

I was having some issues with a bad alternator not keeping my battery charged up, and this little meter helped me see that it wasn't putting out enough amps and diagnose the issue. Bonus points for keeping my phone topped off too.

No bad for the price

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.

Better than expected. Fast Shipping. Will order again.

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.

Sturdy and bright display
