Worry-free shopping
Great little USB car charger to have in the car for charging accessories, good price, easy to use, very durable and displays the car voltage output through the cigarette lighter. I'm very happy with my purchase and I would buy again maybe to give as a gift to some of my friends.
I bought this to monitor the voltage in my car. The best part about this unit is the leds are not super bright. The size is perfect and the color too. I’m in love with his item. 5 star seller too.
I'm very pleased with this meter. I've owned two of these,I like the color, the display, fast charging and that it has USB ports.
I bought two. The voltage readout is so nice! But it stopped charging fast. Strange.
I have a newer vehicle with plenty of charging ports, so I did not buy this for the charging ports. What I did not have was any easy way to monitor my car's voltage. That said, this is a nice dual charging unit. And I like the color.
