DROK Digital DC Voltage 10-170 Degree Fahrenheit Temperature Monitor Car Motorcycle Battery Voltmeter Thermometer 12V 24V Temp Volt Tester Multimeter

Works Great.. very accurate with voltage and Temp.

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 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.

Inexpensive. First impression is good! As others have Mentioned, the brightness is very impressive, at night.. it’s even a bit much. Several people have mentioned the temp accuracy. The thin wire you see in the Photos is the temp sensor. I lightly bent the cable so the sensor peaks out the front of the unit near the display. This has resulted in accurate cabin temp. Overall, I’m very satisfied. Hopefully long term the unit continues to impress.

I really just needed a replacement USB plug, but got this one to try out. I really like having something in my quite old pickup truck to tell me the temp and voltage. Didn't really consider how convenient that was before I had this. Temperature and voltage readings are both accurate. Built much better than my old USB plug. Easy to read display. I do with it had 2 USB ports, but 1 is good enough over 90% of the time. The location being on the top is a little weird in my truck because it means the cord plugs in sticking straight up. I suppose if it was for a dash mount (GPS, camera, etc), this would be perfect. For my phone laying on the seat, the cable has to bend over. No big deal. If I did have a dash mount, I wouldn't be able to charge the phone though because of the single USB port. Works great though. No real complaints.

item worked right away upon connection. good product.

Perfect for my older truck, for battery level and inside air temp

This really works well with my car

This has proven to be an excellent way of tracking my battery in the truck I own. I will also use it in a teardrop to check battery level especially when I am 'off the grid'. The thermometer is a nice bonus.
