DC Blue Car Voltmeter

Installed on our travel trailer, ran wires to the inverter to the cabinet by the door, ft right in looks like factory. Works great, you can check your batteries while coming in the door.

They are not dead accurate, but what do you expect from an inexpensive volt meter...One of them reads 0.1 volt low, good enough for reference to monitor voltage.The second one reads 0.2 volt high... again, good enough for reference...They are doing what I bought them for, monitoring the voltage output of a power supply.Would I buy them again? You bet! They fit just right in the case and are doing what I need.

Works well, easy to install, good looking quality.... Dim and outside in daylight it's hard to see. Wouldn't recommend for outside light.

I am using this product on my RV... 34ft Open Range travel trailer ... I have had converter issues lately and this meter lets me know the charge of my 12 battery... which is used for lights .... and other jobs in the RV.. at a glance I know that the converter is working properly ... Highly recommended ... Thanks ...

Unit works well, but the blue LEDs are harder to read in sunlight than my old red ones.Jeff

Easy to Install and bright

I bought 4 of these to make a gauge cluster to monitor voltages for my stereo system. After 2 days one of them just quit. Update, the other 2 meters are working good and this company is very good about taking care of any issues for this I do give credit.

Product worked really well, had no issues with it.
