DROK Digital Voltage Temperature Monitor, Car Charger USB Charge for Car Battery Voltmeter Thermometer 12V 24V Temp Volt Tester Multimeter

I love both of these meters. I like the colors. They are easy to read at daytime.I like the additional temp gauge. It's nice to know the temp INSIDE the car as well. The voltage readout keeps you informed of battery health and if your alternator is charging, possibly alerting you to a future breakdown. I'm glad they come in pairs. One for each car.

It’s very easy to use just plug and play. If you’re a strange person like me that wants to know the inside temperature of your vehicle then this is perfect for you. My truck is older and doesn’t tell me the temperature of inside the cab or an actual number of how many volts my battery has. I’ve had it on my truck for about a week now and I like it. My AC is working good and I know the exact temperature of the inside of my cab. It has a very clear LED display and for the value it’s not a bad deal.

I bought this item twice for my 2 cars... I find it very useful in determining the car battery life whether time to replace or not & also in determining the temperature inside the car whether the aircon functions well & comfortable cold enough in hot weather especially during summer season.

The media could not be loaded. Easy to read, fits well, the temp and voltage is rounded down. Accurately measures voltage and temp...tested against a multimeter and thermosensor.A 3rd feature, is it let's you know if the car battery is on/off if you are using a kill switch.Will update if it fails.November 9th, 2024 still works perfectly even in cold weather.Still works, June 28 2025 !!

We panicked when we received it because the packaging said the temperature was in Centigrade and we had ordered Farenheit. Luckily, the item was in Farenheit. It works great. My husband thinks the LEDs are a bit bright, but they do the job.

Easy to read and accurate. I hate the blue digits but that’s a plague on many displays. Green is much easier to read.The temperature is displayed with a leading 0 digit which is unnecessary and annoying.The human eye is not designed to see blue and red at the same time, I wish someone would tell that to the designers of so many digital displays. It’s not DROK, it’s very hard to find displays with any other combination that blue/red.

Already bought 2 of these awesome gauges and they keep up with Arizona heat

My 2024 Honda goes bonkers if the battery voltage is below 10 at start, which it has done on more than one cold occasion. The Honda fails to provide any diagnostic information (such as "you battery voltage is too low". The Honda also fails to show cabin air temperature. This meter provides both pieces of missing information, with a nice bright readout.
