DC 12V Car Digital Voltmeter LED Display DC 5-28V Voltage Volt Meter Waterproof Gauge for Car Motorcycle (White)

This works very well; I like the look, I can keep up the battery, and I have a lot of stereo with a lot of power, so this makes it easy to check.

Received In brand new perfect working condition. And very well packaged! I’m using these.on power supply’s. Yes they have analog amp and voltage meter on them. But I like these because of the voltage adjustments on them. If for some reason they get bumped it’s hard for these 71 year old eyes to see. Plus you get a second reference to what’s going on. I’m old school measure twice or three times then cut once. They work very well mine have the white display and they have other colors. These are a perfect size as well. They attach to the front of your power supply easily with the included two face tape. For me I used 3M locking Velcro. Works great! I might buy two more for my other supplies. You also get a nice length of wire so mounting them anywhere even on something other then your supply. Very nice product and highly recommend!!!! 73

EXCELLENT..VERY HAPPY 😊

I'm using the Green voltmeter panel with 2 series 12V AGM batteries. Accurate enough at 27.4V float voltage. Display is reasonably bright in low to moderate light but avoid direct sun which washes out. Display runs fairly warm at 27V. Using this indoors so not sure about water resistance.

Bought 2, neither worked even a flicker. Junk

Not accurate, but still usefull

Voltmeter as described-Installed in my car and truck to monitor the battery and alternator output-Works great-Numbers are easy to read-Easy installation-THANKS!!!

I bought two of these. The first lasted about a week before having issues and then just going dark. The second one has been running perfectly for quite a while now and seems rock-solid. For the price I'd buy it again even with the one failure.
