Mini LED Display Digital Car Voltmeter 12V/24V Vehicle Voltage Gauge

Given the low price this sells for, I wasn't expecting much, but then again, I didn't need much.

I have a second, dual battery on my pickup that is isolated when the ignition is off, and I run several things off of it, and just wanted a cheap and easy way to keep any eye on the voltage, and this gets that job done.

The construction feels cheap. In fact, the little screw part on the end you put in the socket, that you would normally unscrew to change the fuse, is made of plastic even (except for the electrically conducting tip). Don't recall ever seeing any type of thing you insert into this type of socket not being metal for that part. So with that in mind, I wouldn't expect it would stand up to a whole lot of taking it out and putting it back in repeatedly. If you're going to stick it in and leave it, it will probably be ok.

The LED display is red, and I was worried it might be too bright, given the socket I was putting it in is on top of the dash, I was concerned it might be distracting at night. I was pleased to find this was not the case. It's just bright enough, and not too bright.

As I said, it's cheap to purchase, it's cheaply built, but it gets the job done if you're just going to stick it in and leave it. With that in mind, I'm pretty happy with the purchase. I might even have went 5 stars instead of 4 if that aforementioned part had been metal instead of plastic, which is the weak point on this item, in my opinion. If you want a cheap gauge to keep an eye on the voltage, go for this, you likely won't find better at this price point.

Works great, however, digital display was red and not blue on the one I received unlike the one shown in the picture. Would have given 5 stars otherwise. I was looking for it to be blue as described so it would match my cars indicator and dash lights. Luckily there are some red lights in my car as well as such was still able to use it. If your lucky enough like me to have a car which has the cigaret lighter outlet in a convenient place for a digital gauge you can plug in and forget about it and will always know and monitor your voltage every time you in your car. Nice surprise as this device is intended to test as needed rather than staying in place as I have done. Saves from having to run a voltage meter with another kind of gauge if that's what your going for like me.

One of the best buys I have mad from Amazon, I have an older RV and have had some charging issues, this voltmeter is the answer to monitering the charging system, and it was much cheaper than buying an analog gauge, not to mention it plugs right into an outlet on the dash and gives you an instant reading. HIGHLY recomended

Cheap, dirty and effective. I needed to monitor my electrical system as my battery is getting old. Just plugs into the lighter socket and has a very nice readable display.
