Questions & Answers

Would anyone be able to tell me the amount of current this meter draws?

The solar panel drains the battery more than the solar panel can charge it when I install it on my gate opener battery. Additionally, if the sun shines on it, it is impossible to read the voltage.

Does this install automatically or do you have to do it manually?

Alternatively, you can use a 12 volt supply like a cigaret lighter which serves as a power source when the key is turned. In the next step, you will attach the positive and negative from the voltmeter to the source you have selected. If you want to mount it in your dash, you'll need to find a spot

My head unit is already hooked up, can I connect this to it directly?

A voltage of 12 volts is indicated here. Are the jacks on the unit you are going to hook it up to car jacks? It will work if that is the case.

I love how it works! Using this thing is a breeze
5/5

With regards to the water-proof feature, I personally believe the front display section of the product is waterproof. Waterproofing isn't available in the rear portion of the battery case, which is where the cables are located. In looking at the gauges, it appears they were designed to be inserted through the dashboard front panel. I am positive the gauge would work fine if installed in this manner with some kind of RTV or gasket maker to seal off the back portion from moisture. Another solution would be to coat the entire back with hot glue to prevent it from rusting. Installing a gauge in my car's dash is on my to-do list. As such, I consider this a success. When I tested accuracy, I found it to be excellent. There is only a display of If, for example, the battery is at 12, then, for example, A gauge that displays 12V will be displayed at 18V. A two-volt battery. However, if the battery is at 12 volts, the phone will not work. If the gauge is at 11V, the reading will be The first ventilation. There is a lot to like about this gauge. The following picture shows the accuracy of the data. There's a lot of bad lighting in this photo,.

The installation was performed in my Jeep to monitor both batteries (isolated from the rest of the car). The green one monitors the output from the altinator, it consists of a halo ring that you put over a cable you want to monitor, it.

The meter is of high quality at an affordable price
5/5

Easy to use and compact, this little device is a nice addition to any home. Originally, it was installed in my 1980 Westfalia VW Camper Van to keep track of the auxiliary battery. As an OEM battery check switch, it is located on every VW camper and I wired it up to it. With the new digital readout, I now get a detailed readout of my battery status instead of an LED idiot light! It's a great price for this little LED Digital Voltmeter, and it's very well made too! With some careful measuring, I was able to use a Dremel tool to cut the metal in my VW Van, then pop the Voltmeter into place. Using a wired connection, I wired the power switch to the OEM switch and LED lights on the original battery tester. There are a lot of bright colors and it is As long as it is on the clock it seems to use very little power, so that is good. I can turn it off at any time or watch the battery drain over time when it is left on. Since it is bright, it may not be a good idea to have it on in compartments where you sleep without an on/off switch to go along As long as I needed a digital readout for voltage, I would absolutely pick this up again.

Volt meter of excellent quality at an affordable price
5/5

Currently, I own a 1994 Toyota truck that I use for gardening and hobby purposes. The thermostat and gas gauge are the only gauges on the car. This had to do with my desire to know how my battery was performing, so I purchased it. This product works great, has a simple installation process, and is easy to use. Despite its blue color, the digital display is simple to see and works well. This is a device I highly recommend if you need.

It's easy to see, but don't look at it directly in the sun
4/5

I love the size and clarity of the display, but the blue text is nearly impossible to read in direct sunlight. It's a bit hard to install since the hole needs to be drilled in a rectangular shape, but overall I really like it. I would also like the leads to be a bit longer, and the connections at the meter to have more protection, but 1/4" of electrical tape address those issues as well.

A simple, convenient way to make a donation
5/5

In the trunk of my motorcycle, I'm installing this to see how much juice my battery has left. As you can see, the leads were easy to attach (but it would have been nice if we could have had a couple more inches of wire), and it fits easily into the top of the trunk. I don't have any complaints in this regard.

I am pleased with the results thus far
5/5

In my RV, I am checking the battery using a Voltmeter. You did a good job. In order to protect it, I made a 3D enclosure. In addition, a switch has been added so it doesn't draw power when the RV is parked. In this case, the voltage is zero. When I use a multimeter, I find it to be 2 volts lower. I am not sure if this is due to calibration issue, but it is not an issue that will affect how I use This is a good deal with an attractive design, good functionality, and a decent price.
